Description
Fits: 2024-25 Chevrolet Silverado/GMC Sierra 2500/3500, including AT4X/ZR2 where noted. Diesel catalog applications use 6.6L Duramax generations in these years.
Cognito has coined this package as the 'Super Stock Kit'. Since you can not add a leveling kit to this model truck, this package will improve the stock truck via better ride and improved longevity. Read on to hear why and how. The 2500HD AT4X and ZR2 already comes 'leveled' from the factory via torsion bar and torsion key clocking.
