hey i hate to do this but here goes. i got these bilstein coils when i traded my air suspension. installed properly and now i have a problem with the left rear sagging even tho the adjusment is set to the highest point please if anyone have any info on what i can do to get this fixed. let me know thanks

Maybe post some pictures? So you have the perches turned all of the way up as high as they will go and the rear drags on the ground or is it un even from side to side? Where the coild new or used? Where the rear springs the same length before they were compressed?

Here is how mine looks on the Bilstein coils set as low as they can go in the rear







That is the lowest it goes in the rear so all the way up would likely be 2" higher...not what most people would consider sagging but with out pictures of yours it is hard to say.

i got them used when i traded my air suspensions. when i installed them the right adjustment is set in the middle and i have enought room for one finger. now on the left side i have the adjustment set all the way up. but then i cant even get a finger in there.

this is the left side that i am having the problem with

is that how you have your rear springs installed please let me know if i am doing something wrong thanks

Those don't look like the originalnstop collars? But I would say one of springs might be worn out? They appear to be installed right. I would get some new springs for the rear, any aftermarket lowering spring will work, the rear bilstein ones are progressive rate springs but linear rate ones will work as well but the ride will be a little stiffer.

i just need something to hold up my 2 15subs

do i have the springs the right way. cause on the bilstein intallation manual says the skinner side goes to to the bottom is that how you did yours

No the larger side goes to the bottom, the spring perch on the bottom will only allow it one way it will be very obvious if it is wrong.
