I have Bilstein rear shocks and would like to upgrade them to the infinitely adjustable threaded body style. I understand a few members have done this and I'm just trying to get some idea of who sells the kit...or who has made their own...and what parts were used? Thanks for any help on this subject.

here you go...just make sure you get the right ID, they have 2 different sizes for the Koni's and other shocks...there are also different lengths of the threaded tube.

Coleman Racing coil-over kit..one of many (the one I am using on my boge shocks

I checked out Coleman Racing & Ground Control. Looks like the threaded body slips right over the original shock body...correct? I'm curious how it is adhered? Do you slip it over and pin it or set screw it or weld it on? How did you do it?

Your Bilstiens should have a circlip in one of the
4 or 5 notches in the shock body. The sleaves are
close enough tolerance fit that they simply rest on
that clip.

That makes perfect sense. What set up do you have and what diameter springs are typical....2" and/or 2.5"
