: Rebuilding for 36's, or more...
okcrawler 02-26-2002, 06:12 AM I took a run by Jayson's shop last night and check out where he is with his rebuild. He's got the front axle mounted and now has an idea on how big this thing is going to be :). Total height will be about 7' tall, without the spare!
He'll have about 26"of belly clearance...

He is just about to start the rear, he's shooting for 95" WB.

Here's a shot of his front coils setup...

When I get a chance (soon) I'll put together a page on extreme4wheelin tech section with more images (and larger)... :rasta:
0ILBURNER 02-26-2002, 06:22 AM Lookin' good - do you know what coils he went with? Did he fab all his mounts?

He did 5"x16" stock car springs, I believe they are 225 lb rate. Yes, he fabed all his mounts, and the top coil mount is adjustable. The rate is kinda a guess at the moment, but since he's got a 425 lb motor and is adding a 203 dual case, we expect his rig will exceed 4,000 lbs this time!
I've got more and bigger pictures posted on the web page now.
Ok I maybe dumb but I ain't stupid.
Is that a Turbo 350? The motor is a 4.3L? How long is the whole powertrain? Sorry for all the q's, I'd like to run a crawler box but I can't figure on how to make it fit (I don't want a 95" wheelbase). I also have the burden of O/D (length) to worry about.
I'm not an engineer but... :flipoff2:
Ok I won't do it. It is still sweet work though!

Yes he's got a T350 trans, with a D300 T-case in it now and his rear drive shaft is longer than a stock Sami! However, the 203 and adapter, I beleive he said, will add 7" length. He made his own 203-D300 adapter and it is physicaly as short as can be made! He just barely had room to spline the shaft. The biggest issue is with the height of the 203. It will be mounted upside down, and he his planning on cutting out most all of his floor pan. It'll be a sweet setup, but very HEAVY!
That's what I figured. I was going to make a "KloneV" to use as my adapter from a 700r to the dana 300. I didn't think I had the WB to do it but now (looking at it again) I know I will have a longer than stock drive line so I might be able to do it. hmmmm...
2.62*2.72= 7.12 for the t'case
3.0 first gear * 3 (for the torque converter)= 9.0
4.88 axle gears
===============
313:1!!!! :eek: :flipoff2: :D
Then we add a 4:1 kit to the t'case! :flipoff2:
477.8:1!!!!!!!!!!:eek::eek::eek::eek:
Now I'm excited.

High5 02-26-2002, 06:02 PM tell him to shoot for a 100" wb .....he won't regret it.

No way. I already believe it will be too long. I think he should only go to 90", but he is spooked about rolling over forwards. 95" is going to be to long for 36's, and when he goes to 38's his D44 outers will not hold up! Then he'll be back to where he was with the Toy birfields and 33's, breaking an axle every other time we went out!
But, he knows my oppionion, now I just keep my mouth shut and help him get it done in time for Moab in May... :rasta:

95" too long?!?!?! heck no. i have two buddys with zuks on 36 sx's and both have a 97" wheelbase. i don't think they are a bit too long. i definatly don't think they should be any shorter than they are. i have seen them work and if you talk to them they will tell you that they love the longer wheelbase. oh well he'll find out one way or another.:D
nuttzack 02-28-2002, 01:33 AM Stock 79" is way too short in my opinion. 100" is pushing it, and 95-97" is perfect. I am currently at 97" and I think it will be perfect for 37" tires. I would think that 95" for his setup would be awesome. Why do you think this would be too long? It would be crazy not to lengthen the wheelbase if you were gonna do what he is doing. I mean its not like he wont be high enough for a decent amount of clearance anyways so high centering shouldn't be much of an issue, even if he did go 100". I realize you can have your own opinion, but why wouldn't you wan't him to lengthen it?

Personal opinion. I want a vehicle which is highly versatile; a Samurai is light, agile, and very maneuverable. I've worked to keep it that way. At 83" on 33's I have been very happy with how mine works, and I can literally drive circles around anyone in the group I wheel with. I can drive in and out of places no one else can, with the price that on a few obstacles I need a little tug to get over (literally a couple guys tugging on a strap!). I have never rolled my vehicle over backwards or forwards (yet :) ) and I run stuff that many CJ7's won't try. So, wheelbase, is it worth the sacrifice for a little bit more climbing?
I just have to remember to slow down when I'm leading,,, it takes the other guys a while to get thru the turns. :D :D
Wilson 02-28-2002, 09:20 AM The D44 outers can hold up to 38's. If you're really worried about it, run ctm's and alloy shafts and he should pretty much never have a problem. I'm going to be putting alloys and spicer x joints when I move up from my 37's this summer. Having an ARB helps a little bit, since it's only locked when I absolutely need it.

Dude, you've never wheeled at Disney :p....
I've heard how Toy Berfs will hold up to 36's, but Jayson destroyed a Birf every other outing with his 33's. Hell, I've already killed a 297 with my 3,000lb sami and a 4 banger! I'll take bets he can't make it 3 months on his 36's without blowing up a D44 axle/joint/stub... :D
It's not that he drives that hard, it's because we have this ongoing game of, 'If you do it, I can do it' :D :D :D
Wilson 02-28-2002, 09:52 AM I've seen them hold up. Sillyneck is running a 44 front in his YJ with a 5.0 HO motor, 4spd and tera low D300. He has yet to break a stock ujoint and doesn't baby it. He ran the sluice box 8 times last year with 40's during carnage on the con, no problems. I'm going to be stepping up to prety much the same drivetrain and try to keep the D44. D60's weigh too much for my tastes. I know all about those if you can do it, I can do it games. We all find ourselves in trouble with those. I went straight to the D44 becasue I didn't want to have to mess with birfileds.
95 " should be a nice wheelbase. I've set mine to end up at around 98". One question though why build it so tall?I'd lower it a bit and hack the fenders, it'll wheel way better.
I've set my frame height to sit at around 22"-23" on 36" sx's which is plenty of height if you skid plate the bottom (I'm going for a totally flat belly pan).
I don't know though just looks a little top heavy with the exo and stuff.
Another thing is the lower links look to be at a pretty steep angle. whats he running a custom radius style arm on the one side and just a single link on the other?I'd consider making the lowers a little longer and possibly the same as the rear in length.
not knocking it just a few thoughts and concerns I see in his truck and thought about when I was planning my build up also.
Nice truck.:D

Just a question cause i dont no but is that a normally way of mounting a heim joint I thought the bolt should be between
2 pc. of steel and the heim in the center, isn't that alot of stress
being put onto the end of a bolt:confused:

Yes, he his doing a 'wristed' or Y-link setup. I'll probably do something similar on mine this summer, depending on what we learn from his :). On the angle issue, yes we are both concerned with the angle. However we studied the placement for quite a while and what we decided was that the attachment point to the frame should not behind the CG of the vehicle. Imagine if the front arms were back 12". Now the attachment point would be behind the CG of the vehicle. Now picture you're descending a steep hill, and the front tire(s) is pressed into a ledge. If the control arm is angled down at 15deg, and there is, say 800lbf pushing against the ledge with the front tires, then there will be 200lbf pushing UP on the frame at the attachment point! If that point was behind the CG then the 200lbf is now LIFTING THE REAR. A similar effect would occur under braking, either way that's a very bad place to be mounting a lifting component. So, he decided on a compromise. There is a good chance he'll have to lower the truck, he knows that and has a backup plan. :D
Rockrat - As for the drag link, well that's not the best way to mount a hiem joint, especially when you consider his steering box is a 1 ton GM unit :p. Right now we need to get his truck moving again. Then I'll bug him to fix some of the 'little stuff'. I've build several x-over arms for D44's, and the one case I had like that I welded a 3/4" stud turned from 1-1/4 stock to the arm at the corrected angle to take the load off the heim and correct misalignment. That made for a very clean and STRONG setup, and I'll recommend it to him after he get the thing rolling and we know how much flex it's gonna have and the final ride height… :rasta:
