2.5-Inch Lift Kit with M1 Adjustable Struts for Silverado/Sierra

About this kit

2.5-Inch Lift Kit with M1 Adjustable Struts, fitment-checked

This 2.5-inch kit swaps in M1 adjustable monotube struts with a 0-2 inch range, so front height can be dialed in rather than fixed. It covers 2007-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 in 4WD, RWD, and AWD. Stamped steel lower control arms require strut disassembly for the pre-load spacer; cast aluminum and cast steel arms use the upper strut plates. Denali, Denali Ultimate, and eAssist trucks are not covered.

The adjustable M1 monotube struts are the reason to pick the 1340 over a fixed-height kit in this range: their 0-2 inch adjustment lets you set the front where you want it and change it later. Coverage runs 2007-2018 across Silverado 1500 and Sierra 1500, including 4WD, RWD, and AWD trims from WT through High Country. Before ordering, identify your lower control arms — cast aluminum and cast steel trucks use the supplied upper strut plates, while stamped steel trucks require strut disassembly instead. Denali, Denali Ultimate, and eAssist models fall outside the fitment.
