I just purchased a complete set of Bilsteins for my 01 Expy. I am familiar with shocks and chassis stuff, but i only have one question. Can I run the rear shocks shaft down on this application, or do I need to go with the shafts up???That is the question I did forget to ask my dealer! I know on some applications you have to run them a certain way. I like to run with the shafts down when I can to help prevent body damage on the rear shocks from all the rocks and such out here. Any thoughts?
I'm new to this forum but I am an avid Jeep guy. I have 15 plus years experience with building offroad vehicles. You have chosen what I believe and my experience has proven to be the best shock available without a remote resevoir. I have seen people run these shocks inverted on many rigs. however, for this application, I would contact Bilstein directly. Don't take the word of a counter parts guy. Some of these shocks are built with different rebound and compression characteristics that could be obviously out of balance by running inverted. Call or email Bilstein for a definite answer.
Jounce is jounce and rebound is rebound no matter how they are installed. The inverted is the best system but only if the shock body does not come into contact with the truck body at any position of wheel travel.
I disagree, Compression and rebound are not the same. Some shock manufacturers tailor these parameters for individual applications to control ride quality. However, some shocks are 50/50(rebound/compression) For example drag racing shocks are biased for loading the rear end during launch(soft compression) but will have a stiff rebound to hold the weight of the vehicle over the rear axle as long as possible. I know that wasn't a good example but it was all I could think of, it's late.
Yes rebound and Jounce should have different levels of dampening. But rebound travel and jounce travel are the same if the shock is set up inverted or right side up, Thats all I was saying since the question refered to installation set up.
