Use that to replace the shackle. Eliminates shackle interference when cresting if you have a shackle reversal, when approaching if you don't.

I have seen one on a rig, but the rig is not finished yet. Thus no performance update. You must make sure the slide area is enough to provide for the spring being completely flat. I like the idea, just not sure of the benefit.

*edit*
The rig I referenced uses them to replace the shackle, although they are of a different design using HDPE on the slider instead of bearings. I don't know if i would trust those small bearing to carry the load of a leaf spring in rock crawling. I also wouldn't want to see the ride for the bearng smashed so that it couldn't move.

Bigdude, that's what I am thinking, if it has enough throw, I could replace the shackle on my reversed shackle front end to gain a little clearance.

Seens them on more than a couple of rigs around here - IMHO - I have not been impressed.

They generally limit flex since you lose one bushing allowing the spring to twist - but I think Scott @ Rockstomper built one similar but had a pivot at the frame mount - taking care of that problem.

Be warned - they are MESSY since you need to keep them greased and dust/dirt will ear them up in short order...

The only thing I would worrk about was the toughness factor. Could the bearing stand it?? Would the structure bend easily on impact?? Only one way to find out :D How much is a set of those from said race shop?

It looks like a good idea, no more shackle inversion/bent springs for us non srs types. Only problem I see is that its meant for the go fast crowd which doesnt twist springs like we do, I'm not sure how those little ledges for the bearings will hold up. One way to beef this up would be to run a teflon slider inside the bracket so that the spring eye rests on it, but that would be tough to keep from binding as soon as some crap got in there. Maybe just beefing up the construction of those ledges would work.

I have seen that set up on a lot of the hybrid cab trucks running around Tellico. Never seen it actually work because i usually dont wheel with that crowd....but i have seen it.

Bigdude, that guy at tellico labor day weekend that had that red and blue cj w/ the 1/4 elliptical rear had it (if im not mistaken)...wasn't that shackle that connected the spring to the axle tube kinda like this?? Im not sure, it looked like it was kinda the same thing, anyway it just looks like a cheap way to get more drop...it got that guy a lot of drop and articulation, just way to much, and no limit straps. If done correctly it would have been pretty sweet, but it looked like he was just going for who can ramp the farthest.

The teflon one pictured here is $30.00 and the roller bearing one above is $40.00 each.

That's very similar to the one I have seen. I saw them used to eliminate the shackle in an SOA shackle reversed application. For $60 it might jus be worth it to try them. Probably have them on in a day and off in about 2 hrs if they suck :D I would consider using them because I do not have a reversal, and although 38s make it hard to hit shackles, I still have. Would be neat to sink them into the frame rail a couple inches. I believe the dude who invented revolvers is getting ready to market something similar. His is a type of shock body that eliminates the need for a shock on the spring pack and allows for pivot of the spring.

Snoop- That guy had them in a 1/4 elliptic where your right, they were useless.

I've seen those on a couple of rigs at Tellico. (One of which was a turbo-charged TJ 4-cylinder converted to leaves :confused: that broke a 14-bolt rear shaft with only 35" boggers.)

They didn't seem to make anything flex any better than normal. The teflon pads on the teflon version bend inwards and break easily though. The ones I saw were similar to the one with the bearing only, instead of a bearing, just used a rectangular piece of steel, similar to the teflon one. The small metal piece always was bending in toward the center where the bolt came through. IMO, it's just too small a piece of metal to put that much stress on.

I saw that guy break that axle down on Lower 2. I figured it was just a TJ body on some other frame.

A few of the guys in my 4x4 club have those instead of shackles. They made them themselves and are much beefier than those in the pics. I seems to me like a whole lot more work for no real benefit, other than to get the shackle out of the way.

It appears as tho the teflon one os the "light duty" & the roller bearing in the "heavy duty"

hey your buddy jeeper111 is talking about weight in another post, thought you might want to get over there and comment :D

Also what happened to the Vols, I heard the Gators put a whoopin' on them IN KNOXVILLE :eek:

The only benefit I could see is eliminating a protruding shackle which could cause some serious problems in a competition setting and having to realign the vehicle. For trail riding, I'll just take some backs and make the shackle miss the obstacle :D

Well our season opener was against Clemson and we play the Crummy Tide this weekend. What do you consider a real team? My brother goes to AU, so I will be there for that game. Maybe I'll even bring my Jeep and we can do some wheeling.

Congrats on barely squeeking by those yankees last weekend in double overtime. If it wasn't for Cadlilac, ya'll wouldn't have stood a chance in hell. I can't wait till the Dawgs come barking into the litter box ya'll call a stadium and bite the hell out of your screaming-eagle-kitty-plainsman-pussies. What the hell kind of school names their eagle "Tiger"? That's like me naming a pet bird "Cat," or something. You should get a tiger and name it "Golden Eagle." Oh, but if you got a cat he would eat your bird, so that doesn't work. It probably has something to do with HAVING A MILLION FRICKING MASCOTS THAT DON'T MAKE ANY SENSE. Or maybe you could spray-paint your eagle orange and black and pretend it's a tiger.

I seem to see a hint of mis-information floating around here...


You guys do realize that these kinds of shackles do NOT add more clearance that a standard shackle - right?


It may visually *look* like you have more clearance, but assuming no other changes in the suspension - the spring eye is in EXACTLY the same place it was, but now the frame of your Jeep is LOWER to to the ground.


So although these sliders may offer a better surface for clearing the rocks - they do not offer better "ground clearance"... and I would argue they are actually worse for ground clearance.

Damn, I believe he may be right, basically all it does is lower the height of the truck a little.

I contemplating using this type of thing in a SOA config. I think it could aleviate alot of the problems some people have with SOA. I would guess on average you would get about 2inches less lift also a SR would not necessarrily be required in the front and could increase castor angle improving handling in most cases.

They have been using those for a few years now on the rear of class 7s desert racing trucks. Like kwrangln said, more for the go fast people.

I could see the advantage to running them if their lack of lift was taken into account when builing/buying the spring... The disadvantage I see is relative to the fact that you lose the leveraging factor a shackle can provide on compression once it passes 45 degrees...

Flipper
09-30-2002, 03:57 PM
Another benifit is a more consistent spiring rate throughout the whole compression cycle. With a traditional shackle, spring rate goes up as the shackle is pushed back.

I am building sliders for my YJ SR conversion on the front of my Zuk. It is going to allow me to mount my springs flatter....less lift/more ground clearance since the rear eye of the spring won't be pointing down (lower than the axle tube)

Actually the TJ you saw on lower2 is one of my buddies here in Cookeville, we built the tj a little over a year ago, just to try something different. It has a stock 4cyl with 5.13 gears in it. We put the leafs on it because he did not have the money for a big coil spring lift. Alot of guys have been runnig sliders for a longtime. Tommy Roller in Mcminnivle Tn, has run them for 10 years or longer with bearings on them like in the first pic., we put teflon pads on the tj. Tommy told me circle track cars have runthis design for a very long time and seems to work good. They offer a little bit more compression and droop, but also allow for more axle wrap on the front end. We have not seen them out perform SOA with shackles. They are different but you do have to keep them lubed or they get a bit noisy. :jeep:

Did you ever determine HOW THE HELL he broke a 14-bolt with a 4-cylinder and 35" tires?

The best we could figure is when he tried to jump up the ledge, he was give'n her all she had, and when it came down that was it, the boggers hooked. When we got home and took it apart the shaft was broken about 6 inches from the carrier. We have never figured out why or exactly how a 4-banger broke a 14bolt with 35's.

I saw a rig at the Offroad Expo in Pomona CA last year. Can't remember the name on the rig though. It was used onn the forward mount on the rear spring if I remember correctly, but they also had two link design to keep the axle located in the right place. Looked like it would allow for more droop. I'll see if it is at the offroad expo this weekend.
