My truck is lowered and as everyone knows the wheels sit far back in the wheelwell when lowered....My question is has anyone ever seen a control arm setup that moves the spindle and all forward enough to center the wheel in the wheelwell? I just want this thing to look right front to rear
-
The only way to move it is to relocate the crossmember permanently. Of course it moving back is a result of it being lower, so if you are on air or plan to lift it, you will have reverse of the same problem.
-
I am not trying to center the wheels side to side but front to back....I agree with relocating the crossmember, has anyone ever done it
-
There have been several people that have done it. Porterbuilts do it by design AFAIK.
-
I have DJM upper and lowers on mine, and honestly i cant tell the difference to where the wheel sits.
Before (not the same shot, but as close as I have)

I have lowering spindles and springs on my truck, as it is lowered, the wheels get further back in the well....I would love to go to tubular control arms someday, but just want to make sure that what I get is gonna be the right thing....You know crossing the T's and dotting the lower case J's
-
Ok, gotcha
-
No one makes arms to relocate the wheels. You can buy the Drop member for Porter Built, or the raised cross member from Suicide doors, or you can modify your stock set-up yourself.
-
The only time this is a real issue is when you are on bags and have an extreme drop or if you cut WAY to much out of a set of springs. If you are above 5" of drop and using spindles this is a non issue.
It only is an issue if the majority of your drop comes from the spring height as this severly changes your suspension geometry.
-
Are you getting alignments after lowering? you really need to to correct the geometry. that should put your wheels back in the right spot.
-
The problem referered to here relates to the wheel being centered front to back in the wheel well. An alignment will have no effect on the location of the weel as it relates to the issue at hand. You are; however, correct in that an alignment is needed after lowering.
-
Yea it will.. it you have too much positive caster, the upper control arm will want to tilt the spindle towards the rear of the fenderwell, making the tire look as if its close to the back of the wheel well.
-
Not true. Putting a huge drop spring will cycle the control arms up as if they were compressing and leave them there permanently. No alignment will ever fix this problem, all the UCA shims will do is fix the camber problem.
-
UCA shims affect camber AND caster , if you install more shims in the front it moves the top of the spindle back, I think after working on cars and trucks for almost 20 years, I know how a GM suspension works. unless you have a solid front axle, you can adjust caster.
-
There is NO way you can adjust 3" of setback on a dropped truck by adding shims to the FRONT.
After dropping trucks for 20 years I know how GM suspension works, you CANNOT adjust this out.

His wasn't that extreme.
