Description
Freight item: this oversize part ships by special arrangement. Freight method and cost must be confirmed before shipping.
Fits: 2024 Chevrolet Silverado/GMC Sierra 2500/3500, including AT4X/ZR2 where noted. Diesel catalog applications use 6.6L Duramax generations in these years.
The 2500HD AT4X/ZR2 model was first introduced in 2024. GM advertises that it includes a 1.5" suspension lift. Our comparison to the standard models disagrees with the front lift claim which indicates an actual 2.5"-3" of front lift compared to the standard models and agrees with the 1.5" for the rear. Rather than calling the front end a lift, we feel it is more appropriate to call it a leveling kit in the front plus an added 1.5" lift block in the rear.
Required supporting parts / notes: not included in this standard package but highly recommended to add-on.
Supplied as the Cognito kit configured on this page. Confirm 2WD/4WD, cab, bed, axle, and any required shock, UCA, or driveline options against the manufacturer application before ordering.
