Requires cutting and grinding. This kit fits models with both cast steel or aluminum factory control arms. Please use our 3.5" knuckle kit. To ensure proper fit please confirm if the stock control arms are cast aluminum cast steel or stamped steel. New lift block replaces the factory equipped block. To ensure adequate clearance when lowering the differential models equipped with a mass damper on the front differential must be removed. Models retaining factory wheels are advised to run no wider than a 11.5" wide tire. Fitment on this page is based on the manufacturer’s application data.
About this kit
3.5-Inch Vertex 2.5 Lift Kit, fitment-checked
Rough Country 19457 mixes damping levels: two adjustable Vertex 2.5 shocks handle the front of this 3.5-inch 4WD lift, and a V2 monotube pair covers the rear. Forged upper control arms rated for 2.5 to 3.5 inches complete it. Fits 2007–2016 Silverado 1500 and Sierra 1500 with cast steel or cast aluminum factory control arms.
The shock package is split on this kit — adjustable Vertex 2.5 units at the front, a V2 monotube pair at the rear — with forged upper control arms tying the 3.5-inch lift together. Fitment covers 2007–2016 Silverado 1500 4WD and Sierra 1500 in 4WD and AWD, plus 2010–2015 GMC Sierra. Confirm your factory control arm material first, because stamped steel arms are not supported. Cutting and grinding are required, a fabricated block takes over from the factory rear block, and 2014–2016 Denali and eAssist trucks are excluded.
