About this kit
3.5-Inch Vertex 2.5 Lift Kit, fitment-checked
Four Vertex 2.5 shocks ride under this 3.5-inch lift for 2014–2019 Chevy Silverado 1500 and GMC Sierra 1500 4WD trucks — adjustable units at the front, matched rears behind them. The knuckles are machined for stamped steel and aluminum lower control arms. Denali, Denali Ultimate, and eAssist models are excluded, and cutting and grinding are part of the job.
Rough Country's 3.5-inch lift for 2014–2019 Chevy Silverado 1500 and GMC Sierra 1500 4WD, built out with Vertex 2.5 damping: two adjustable front shocks and two rear units valved for the 2 to 3.5 inch range. Knuckles machined for stamped steel and aluminum lower control arms create the front height, so factory geometry changes little. Verify what your lower control arms are made of before ordering, and rule out Denali, Denali Ultimate, and eAssist trucks. Cutting and grinding are required, and a downloadable installation guide is available.
