Just got the J springs, What should I use for caster correction? (1 Viewer)

[Jiggy]

Okay, newbie ignorance here. Tried the magic search button and found nada. MAF has the shackles and bushings, Slee has the bushings and ? What should I use? I'm kinda new to the suspension area.

Thanks for any help!

By your sig, it looks like you don't have anything heavy bolted on? No bumper, no winch, no dual batts... IMO the bushings would be a little less correction than what you need, Slee's castor plates maybe a touch too much, Slee's arms probably a bit more than too much. that's my hunch, I suggest you call Slee's, ask for tips, then buy whatever they recommend.

Also if you end up bolting on 200 pounds of accessories, that's going to bring your front end down about 1". Better to aim high for castor, unless it causes driveline vibration. Only one way to find out about that, though..

MAF drop brackets will correct your caster but may not be as good as stock behavior. With no weight and for normal road driving, that might be a viable option. But if you talk to Christo, he definitely will have a better idea. But first have a clear plan for your truck. For example, MAF drop brackets and Slee sliders are not compatible without some grinding and or drilling. My guess is any other bolt on sliders will have the same issue, I could be wrong. Anyway, that's a different topic but some thing to think about. Especially if you have moderate to big plans for you truck .

I put on the J's about a month or so ago on my stock weighted 80. I did the bushings from OME that came with the lift. It helped the caster but I don't think it was enough to get rid of that "dart" like feeling when starting into a turn at speed. I think for a stock truck with J's that Slee's castor correction plates would be perfect because I got about 4" of lift out of the J's. Stock bushings with Slee's plates would've been perfect.........I think.

I've got J's without any weight on the front. I put on Slee caster plates and it seems to be about perfect. I don't notice any ill manners at speeds and I've put at least 5,000 to 6,000 highway miles on them.

i second the c-plates. i would call slee and get his advice.

One thing you guys fail to realize is that is appears he is doing this to his 92. 91s and 92s behave much differently to the suspension than later models. I've had a 91 and 94 both with Js. Depending upon what your plans are for bumpers etc... would greatly affect the advice I would give. If you are going to stay really light with no winch or ARB in the front I'd probably go with the plates. My 91 was really light with Js and a 1" spacer up front and the bushings weren't enough. It still steered fairly quickly. My 94 with 1.25" spacer and Js and caster plates steers a little slow. But really this could just be these two vehicles. Every vehicle has different caster values. No two are the same. The only way to be perfect is go to alignment shop before and after and then compensate.

Personally, I don't have any weight on my rig except for a drawer system in the back. I do not run any castor correction. Honestly, I didn't feel the drivability was bad enough to worry about it, even though I'm 6* out.

That being said, I would check your alignment before you decide anything. If you are out as much as I am and planning on running a bull bar with a winch and sliders, etc. I would just put the OME bushings in and forget about it.

Personally, I think that people put too much into making there castor perfect, which causes more problems elsewhere. You are modifying the suspension to a point that you will not be able to get everything into perfect spec. (no disrespect, just my 2 cents)
