Bought these for my 2003 Chevy Trailblazer and removed the Bilstein shocks. We first used them in our Chrysler minivan, which has a fairly heavy load on the rear wheels, and they performed exceptionally well for vehicle weight control and general on-road handling. If you have a Trailblazer or a factory Bilstein GMC Envoy they are not the best as they are cheap. Bilstein have the best shock absorbers for these cars and the ones I currently rent have been replaced by me 3 years later. returnโฆ
