Huge difference!

I put a leveling kit and off road tires on my Sierra and it drove horrible. Every little bump was jarring. So I decided I needed some new shocks, researched a bit and asked my local off road shop what to do and they recommended these. Best thing I've ever put on my truck. It drives super smooth even with the torsion bars cranked. I've taken it off small jumps and it lands like a baja truck. Couldn't be happier with my purchase. Planning on buying them again once I get my real lift installed

Installed on a 2010 2500HD with 60k. I didn't realize how bad the truck drove until switching to these. It is like night and day difference!

Asked by darksied from PA on

Hello darksied, This shock will not fit your vehicle application. Id suggest the front Pro Comp Suspension Pro Runner Series Shock Absorber Part Number: EXPZX2015 and rear Pro Comp Suspension Pro Runner Series Shock Absorber Part Number: EXPZX2001 for your vehicle configuration. Thank you for the question.

I have an 04 GMC Sierra 2500HD 4x4 and I need to know if these fit on the front and rear or is there seperate part #s for the front and rear. I read someone elses Q&A and the part numbers given for the rear were compatible but when I punched in the 24-186643 it said it wouldnt work on my truck. Thanks

Asked by SGHoug from Belle Plain KS on

Hello Spencer For your 2004 GMC 2500 4X4 you will need 2 each of BIL24-186735. These front 5100 Series Bilsteins will work for 0-2.5 inches of lift, The BIL24-186742 will fit the rear of your vehicle and you will need 2 each of those. These rear shocks fit 0-1 inch of lift. The 5100 Series Bilsteins will be an excellent choice for your Big GMC. If you have a larger lift than what I mentioned here then you will need different part numbers. If you have any more questions please contact me at 877-757-8444 ext 1844 Thank You Jon Snyder 4wheelparts

I have a 2007 GMC Sierra 1500 Classic SLE 4x4, and the front shocks need to be replaced. I have not yet decided whether or not I would want to level the truck, but I was just wondering what type of shocks I should get? Thanks!
