Is anyone here using 63" Chevy springs on the rear of an SII? Did you leave the overload leaf in the pack or did you take it out? Any idea how the spring rate compares to 44044's? I'm trying to decide if I want to inboard the rear springs under the frame rails or leave them outboarded like the stock SII rear springs are mounted. I just don't know how much lift to expect out of the 63" springs.... if I inboard them, I may end up way too tall in the rear compared to the front.

http://www.pirate4x4.com/forum/showthread.php?s=&threadid=20665 (Toy FAQ 63" Swap) I assume you already found some info on this but here is what the Toy guy's are doing. Sounds like they use the 3 leaf with overloads. So for your heavy pig prolly the 4 leaf with overloads. Especially if you inboard.

As far as inboarding the 63" Chevy springs. They are 2 1/2" wide with probably a 3" wide bushing. Since I cannot seem to find the width of the SII frame could you actually inset the front spring eye into the frame. I think that I have seen it on here before. That way you do not end up with anything protruding from the bottom of the frame. Might need to plate the sides of the frame and relieve the bottom opening. Then you could mount your rear shackle through the frame.

Better yet. Quit web building and bring that bitch over and I will setup a cot for you in the barn. :D

P.S. I am trying to bolster my post count so that it actually exceeds the number of years that I have been a non paying member.

I'm running 56's under the frame and I only have 3 leafs left in the pack. I did it that way so the springs would be flat. The only down side is the fixed end is half way down the arch in the frame. So, to make the spring sit level, I had to use a 10" shackle. I ended up with about 5" of lift PLUS the lift of going SOA. I only *had* to trim a little to clear the 37's. I trimmed a lot more just to be cool though:D

It was on a scout 80 but they are kinda close to a scout II.

I used 56 vs 63, chop the overloads ends off leaving about 14" or so. As for spring rate here is a calculator (http://www.therangerstation.com/tech_library/leafspringrate.htm), with 63 I would leave them outside the frame since you will have a ton of flex. I put my 56" rear springs under the frame and they work great, but had to pull the shackle bolts out when I dropped the gas tank.
Not a big deal, but something to consider. As for the mount on the frame ( if under) I made a pie shaped holder that will slid over anything.

I have 4 leafs and will most likely add a 5th as I'm getting tied of the rear end bottoming out. Of course these are used springs from the JY. I bought some of those nice bump stops from Jeff and that might do the trick vs the extra spring. All the other Scouts that have 63's have been scout 80's that I have read about.

I was going to talk with you more about that later. :bounce: :bounce2: :bounce:

I'm just trying to minimize my imposition on your space. I want to have both axles built and the doubler/trans assembled and ready to go in. That way it can get in and out of your shop a lot faster. Besides, I'm giving you time to get full amperage run to your barn. :flipoff2: :laughing:

there are a couple threads in the FAQ that mention these springs, but they are under a 80/800. I don't know if they are similar weight-wise, but uh, whatever.

There are two different 63's that I know of. I use the 3 leaf pack (1/2 ton) w/o the overload. The guys I run with that have 4runners (heavy rigs) run the 4 leaf packs (3/4 ton). Most all of them cut the overload down to about 9'' long. BTW I'm not counting the overload as part of the pack if you know what I mean. I don't know anybody that is runnung ''lifted'' version of the 63's however I will say that they seem soft and will give you axlewrap issues on the trail. If I were you I would snag some 4 leaf pack 63's from a 3/4 ton.

i thought the 3 leaf is in the 2x4 and the 4 leaf is in the 4x4.

Well, I looked at the 63's I picked up a couple of months ago and they are the 3 leaf with overload variety. From what I'm seeing here, I either need to find an acceptable donor and add another leaf to the pack, or go back to the JY and look for a couple of 4 leaf packs.:rolleyes:

Besides, I'm giving you time to get full amperage run to your barn. :flipoff2: :laughing:

That would probably be a good idea.

Not a Scout but I am running them on my 1 ton Commando. The springs I used were from a 05 2wd crew cab chevy. They are 2 leaf with an overload.
When I put them on the rig the two leafs sat right down on the overload. So I picked up another set and cut them up and made one 4 leaf pack with no over load. So far this set up has worked killer and I have pretty much no axle wrap.

Iv got 63"s in the back of my Scout II there under the frame, Mine are the 4 leaf including the overload,i believe there off a 1/2ton 4x4. They seem to be set up pretty well for a full bodied rig. they flex insane and ride really nice. They even hold the truck up on sidehill stuff, they work great for my rig :smokin:

Rogue camera man:D

Looks pretty damn flat and already on the overloads at ride height. I'm thinking I need to look for some 4 leaf w/ overloads.

I guess it also depends on the extra stuff you carry, as that photo of Kevin's was taken on the CON, I'm sure he had a few spare parts back there :) Kevin also cut into his bed to mount the top of the shock higher for more up travel / longer shock . I left my bed uncut and mounted them as high as I could but only have like a few inches of up travel, mine is all drop. Here you can see what it looks like empty, once loaded with spares and camping gear it goes down about 2" That why I will add one more leaf and see how it rides, and/or actual install the nice bump stops I got a while back.

i have 63s under my scout. I used the 1 ton spring pack and took the big over load spring off competly. its awsome.

How much longer are the 63's compared to the stock springs (I don't have access to my Scout right now)? Is the locating bolt centered?

the bolt is centered and stock springs are around 53 i think.

How's the ride compared to stock?

nice and smooth.. the way i had my set up it rode way better then stock.

I used the Chevy truck rears which are 56" same length as stock, but with a 4" offset. This allowed me to mount the front eye in the stock location, but move the axle to the rear. Like that really matters were the eye location is.:shaking: The following week at the JY I found some really nice 63", but at that point I just needed to not get side tracked. My 56" flex nice, I'm sure the 63" would flex even more:grinpimp: I drive mine to trail so a anti sway bar would help on the high speed corners. If it says 45 MPH, don't try 60, as it does not handle like a race car. I also did not want to cut a hole in the bed for a taller shock. I have 13" shocks on there now, so the axle is never hanging from the shock mounts

nice and smooth.. the way i had my set up it rode way better then stock.

X2 mine seem to be just right. and ive loaded it down pretty heavy on some longer trips

Linking it was the original plan.... even have it drawn up in CAD. Cost is the prohibitting factor at this time. The rig would be down for a LOT longer period of time in order for me to save up all the additional $$$ for rod ends, link material and coil overs. Maybe in the future, but it's leaf springs for now.

63" is only 6" longer than a stock SII rear spring. So, to move my rear axle back 6", I only need to move the spring hanger back about 3" on the frame. The shackle hanger will have to be moved back about 9" though.

i've got 4leaf on my scout, not including the overload. it flexes like crazy with the double shackle I've got.

BUMP BUMP.

Im in the process of putting 63" rear springs from a 05 cheby in the rear of my scout. also putting them under the frame. the spring bushing is 3" and the frame is 3". since mines bobbed in the rear Im hoping i wont sag real bad and ride will be good since theyre the 2leaf and overload oh ya soa 60/14 too. he he he :smokin:
Anyone else had any experience doing all this.

I agree.

Like the sig sirmonte "you drive a what?"
found a girl one time that came up to me and said nice scout :eek: shoulda kept her around....
back to topic. I flattened out the cheby springs with my handy dandy custom truck on top o spring tool, found they'r 64" flat, at that length the rear shackle is at 35* from horizontal by my measurements. my question is what is the max angle befor the shackle flips over? I watn to stretch teh wheel base a lil bit while I got the rear all torn down, so if I can get away with a lil more angel from the shackle I'll move the front spring mount back some.

Coverted the 3 leaf w/ OL spring packs to 4 leaf w/OL... still undecided if I will/should mount the springs under the frame or outboard them.

Converted the 3 leaf w/ OL spring packs to 4 leaf w/OL... still undecided if I will/should mount the springs under the frame or outboard them.

Did you get the front done? Out-boarding them would help lower the rear if needed. Otherwise in-board has more flex. Your rear is going to have way more flex then the front either way.

Edit: You could "french in" the spring hanger into the frame to lower the profile too.

What your going to hack up your DD truck for an axle?:confused:
As for under the frame or outside the frame either way with 63" springs your going to have a ton of flex. Your going to have to post a few pic's so we " Mechanos: Tech hungry bitches" can look at your junk.:flipoff2::D

Good eye. :homer: I been F_in around on my Scout the last few months and will need to look hard for all those types of things.

You just reminded me I need fix my front shackle as I forgot about that:eek: The sleeve is too narrow and if I tighten it to spec it won't move. Need to pull the sleeve and weld a small bead around the edge to make a few thousands longer.

Who else has the 63" springs now? :smokin:

I inboarded some 63's in the back of my FSB. I went to the junkyard and spliced a 56 pack and 63 together. Im running 4 leaf with overload. My rig weighs in around 7K (front bias) and tey ride and flex very well. A little soft for my weight, whcih is offset with higher nitrogen in the rear reservoir shocks.

(I know its not a scout, but Im shopping for one)

So, are you running the 63's yet?

Linking with coils and not coil-overs isn't that bad for $$$. Fab is not much more than what the leaf mods would be. With all the brackets available, getting the parts together is the big part, the install is 6-8 hours.

I have a parts list...

:laughing::laughing::laughing:

How much lift can I expect with 63's installed under the frame?

Maybe measure from the top of the spring pack to the bottom of the frame and also the pack thickness. Photo's with the Scout level would be a big help too (need to know the tire size of course).

I'm debating that myself. Do you think it was worth it? I'm guessing it would cost about 6-7 bills for the 4-link w/ coils depending on the joints. $100 or less for the 63's. Only real advantage I see with the links is that axle hop is a non-issue. How 'bout a build thread? :)

Nice write-up. Enjoyed the video. http://vids.myspace.com/index.cfm?fuseaction=vids.individual&videoID=1210448696&n=2

I felt the 53's worked best in the space but mine is an 800 and the springs are under the frame. My shackles are all the way at the back because i stretched it to 106(+3.5 rear and 2.5 front) I took out the overload just because of the way it sticks out. so much flex the rear panels are cut up to the inner fenders.

heres mine with 63" rears stock fronts soa d60 14 bolt. h1s and 36's. nothing really to compare hight too but it should give you an idea.

Thanks for those pics Stomp. Can you measure from the top of the spring pac to the bottom of the frame? How many leafs? do you know how much the rear weighs? Im trying to get an idea of how much the rears are compressed

Thanks for those pics Stomp. Can you measure from the top of the spring pac to the bottom of the frame? How many leafs? do you know how much the rear weighs? Im trying to get an idea of how much the rears are compressed

Hard to tell in the pics, but it looks to me like 2 leaves + the overload. If that's the case, then the packs have had 1 or 2 leaves removed depending on which pack he started with.

my rears are from an 05 cheby 1500 2 leaf and overload stock. Im a front end tech at a cheby dealer so I got a hold of these fo free. plans are to remove the overload. and install another leaf in its place. right now its way soft in the rear and Ive got no idea how heavy the rear is, its missing 18" of rear fender about a foot of frame and the tailgate. with just the 2 leafs it flexes like a slinky but I got crazy axle wrap.

the ass end of mine is a little higher right now both because the overlad is about 3/4 thick and there isnt anything back there. fully loaded with beer, tools, supplys, extra parts, and beer it should be even.

looked at a stock cheby just now which the springs are off of and they have almost the exact arc as my scout they may be a little flatter on the chevy.

when I get home today Ill measure the hight between the frame and spring

they are 2.5" wide and each leaf is .425" thick. completely flat the measure just over 64"

I scored a set of the 3 leaf w/ overload spring packs (which got stolen from driveway by a scrap metal scavenger) but after doing some reading on here I go the impression that they were going to be way too soft. So, I found a set of 4 leaf w/ overload packs and grabbed the 4th leaf out of them. When the spring packs got stolen, they didn't take the extra leaves so I picked up another set of 3 leaf w/ overload packs at the JY on 1/2 off day.

I'll probably try them with 3 leaves and if they are too soft, I'll toss the 4th leaf in.

mo betta pics.
rear spring to frame on mine is 13"

I picked up some 63" springs last week & I'm planning on swapping them in the rear soon.

Most of the write ups I've seen are for the 3 leaf or 4 leaf plus an overload.

My springs are 5 leaf plus an overload.

I'm quessing 5+overload will be too stiff.

What all is everyone else running on their 80?

Here is a cool link/specs (http://littlekeylime.com/MrN/mrnimages/leaf_springs.png) I found...

http://littlekeylime.com/MrN/mrnimages/leaf_springs.png

My old springs are BDS 2.5" lift YJ Springs, which keep sagging/bending.. Looking at the above chart, the old leafs are most likely somewhere between 840-1080.

So if I run 3 Chevy's it should be: 1425, 4 leaves 2025 & 5 leaves would be 2235.

I used 63" on the rear of my Scout II. They were 3 leaf plus overload which I left in. In my opinion the springs were perfect. They rode great, flexed great, and had good on road manners.

Mike The 63's are longer so they will bend easier than a shorter spring of the same thickness and width. Thickness affects it a lot more than width.
so 2" or 2.5" not much difference. But the leaf thickness does make a big change. I'm sure those 63 are thicker, but since there longer it offsets.

The next big factor is where they are mounted on the axle. The closer to the wheels the less force the axle puts on them. Think of it as a cheater bar, the longer the bar the more force. As the springs are moved in on an axle the more leverage the axle has on them.

So in the end, what do you need?

Do you have an anti wrap bar? If not, keep the overloads as it will act like one and has no real effect on droop. It will take some field testing to see what you like. I went with less leafs in the beginning, but found I would bottom out with all the tools I carry. So I added more leafs.
Your not as wide as me, so I would not run all 5 leafs. Try 2 or 3 plus the overload and see if you bottom out. If not ,your good. Just leave the u-bolt long enough to add a leaf or two. It really depends on the amount of spares and tools you carry. I have not weight them, but suspect about 400 pounds with the spare tire. Tire is 150 by itself:shaking:

I have 63's in all my lifted rigs they work great. flex great. i run the 3 pack and no overload. I had them on my toyota before my scout and they tend to work and not get all wavy like alot of springs i saw my friends run. I don't know if anyone has tried them yet but alot of guys i wheel with are running ranger rear springs and they work pretty well compared but smaller rigs. I have some 63's in my lady's 4runner and they work well accept when you run cheap shocks it gets a speed wobble but i put some bilstien 5125's on it and the shocks are stiff enough to make that disapear and it still works good

Mike I know you got the 63, but the 56" might be a ton easier to fit.
I'm running 56-57 in mine. Currently running Ford 150 springs.

But new spring will cost more than JY stuff.
http://www.summitracing.com/parts/SLF-01-336/

Edit. I would take the pack apart and hold the main leaf up there to see how it will fit.

I ran the stock 56" chevy ones and was VERY happy with them. So happy, the race truck is running 56's on both axles. I Did ruin a few packs because I ran 3 leafs and wrapped the shit out of them. 63's just seem like they are more trouble than they are worth really.

But, I'm curious to see how they work for you...

I am running the 3 leaf plus overload 63's in the rear and 57's up front. I ran them for a short time before I built and installed a traction bar. Prior to the traction bar they felt kinda soft but flexed great. After adding the traction bar it feels stiffer for some reason. I left the overloads in because I hook a 2500# tent trailer to it every now and then with great results going down the hiway.

I'm starting to think the 63s are a bit too long. :(

If I run them, the spring perch would sit /be welded to the section of frame that I notched for clearance of the 205.
I can help but fear that it would put too much weight on a weak link on the frame....

Here are the 63s:

The placement you have there looks a lot like where mine are. I have been thinking about stretching mine a bit more by frenching the springs into the frame and mounting the shackles on the face of the bumpers. This would also lower the scout from a 24" belly to around a 21" belly and allow longer shafts with better angles at the t-case.

Here is where I put the front spring mounts on mine.

This is the best picture I have for now of the rear mount location. It is 9 1/4" from the stock bolt hole to the new bolt hole. Those are 56" springs mounted long end to the front. When I put the 63's in the axle stayed in basically the same location but the shackle had to move another 7 1/4" back.

I'm starting to think the 63s are a bit too long. :(

Pretty sure I mentioned that on PBB about 10 years ago...:flipoff2:
