Height Difference
So I lowered my truck years ago and never took any measurements before or after lowering it. I decided to swap some suspension components and lower it about an inch more. I took some measurements and saw that the passenger side sits about an inch higher in the front and the rear. I swapped the suspension components and it still sits an inch higher. Anyone else run into this problem? What might be causing it?
I also searched the forums and didn't see anything on this. If there are any old threads out there please point me to them. Thanks I have replaced all of the bushings (body and suspension) and I have DJM tubular control arms, chopped springs, rear flipped with new welded perches with 1 inch lowering shackles, cal trac bars and I removed the helper spring.

Re: Height Difference
I do know that stock trucks aren't perfectly level, have you had your suspension aligned by a pro alignment shop?? I had this problem years ago when I put a 4/6" drop on my truck and it was unlevel a little bit, then I had it aligned to almost factory and it sat level. So this may or may not help.

Re: Height Difference
I had the front end aligned last time I lowered it. I guess I don't understand why an alignment would change the suspension height. How would you align the rear?

Re: Height Difference
You don't align the rear, but you can set your pinion angle correctly with shims.

Re: Height Difference
Yeah I have checked my pinion angle and shimed it already.

Re: Height Difference
What suspension components did you swap?
Why were your perches re-welded? "chopped springs"...did you cut your coils by hand? Are they stock cut coils?

Re: Height Difference
I had western chassis lowering spindles and original springs that I cut. I now have DJM tubular control arms (3" lower arms) with the same original springs that I cut.
I had the rear flip kit but one night at the track I hooked up good and my rear twisted and ripped the original perches off. So I bought new perches and welded them to the underside of the rear axle tubes. I still have the original rear leaf springs without the helper leaf (now 4 leaves) and 1" lower shackles.
