3.5-Inch M1 Lift Kit with Red Control Arms for Sierra 1500 4WD

About this kit

3.5-Inch M1 Lift Kit with Red Control Arms, fitment-checked

M1 monotube damping and red forged upper control arms in one 3.5-inch package for 2014–2016 Sierra 1500 and Silverado 1500 4WD trucks. The kit carries an M1 loaded strut pair, an M1 monotube shock pair, and arms rated across a 2.5 to 3.5 inch lift range with ball joints already pressed in.

Take the M1 strut-and-shock combination and add red forged upper control arms and you have 19440RED. Supported trucks are 2014–2016 Sierra 1500 and Silverado 1500 4WD, along with the 2015 Sierra SLT. Confirm the factory control arm material before ordering — cast steel and cast aluminum are covered, stamped steel is not. A fabricated block replaces the factory rear block, cutting and grinding are part of the install, and the front-differential mass damper must be removed where one is fitted. Denali models from 2014–2016 and eAssist trucks are excluded.
