Fits 2001-2010 Silverado and Sierra 2500HD 2wd and 4x4 trucks at std ride height OR with increased ride height from torsion bar adjustment or torsion bar key replacement.
My personal preference for smoother ride is the std yellow shocks. The 5100's are valved a bit more firmly to help with off road, large tires etc. -JK

Note: Some vendors sell Ford and Dodge application shocks for these vehicles which I do not recommend. These are the D146/D147 units which are purpose built for the application. Thanks- JK
