About this kit

Rough Country 29840 is a 7-inch lift kit for 2014-2016 Chevrolet Silverado 1500 and GMC Sierra 1500 4WD trucks, built around an M1 loaded strut pair and an M1 monotube shock pair. Cutting and drilling are part of the job. It will not work on trucks with stamped steel control arms, Denali models with Magnetic Ride Control, or eAssist hybrid-package trucks.
This 7-inch lift kit for the 2014-2016 Silverado 1500 and Sierra 1500 4WD ships as a full boxed package: crossmembers, front and lower skid plates, a control arm drop kit, fabricated rear blocks, the M1 loaded strut pair, and an M1 monotube shock pair. The 2015 Sierra SLT is also covered in the fitment table. Confirm your stock control arm material first, and plan on removing the front differential mass damper where one is fitted. Larger tires call for the Rough Country speedometer calibrator, part 90009.
