Review: Easy install - Works as described Review: Good but slight mod needed - Worked well repositioned the shocks as needed, I put them on my 5/7 dropped crew cab.. only issue is they mounted to the stock location perfectly but the part that goes to the shock end was too narrow I had to grind it down to get the shock to fit in there. 5 extra mins of modification, but something to note. You could probably bend them to fit if you didn’t have a grinder. ## Features - Universal Fitment: 1999-2006 Chevy Silverado 1500 all cabs RWD/2WD, 1999-2006 GMC Sierra 1500 all cabs RWD/2WD. - Material: These shock extensions are constructed of heavy duty stamped steel, strong and stable, will not easy to crack or break.
