Explore New Heights: GMC's fifth-generation Sierra 1500 features an impressive all-new design that's built from the ground up, with aggressive angles and head-turning stylings that fit in beautifully when transformed with Rough Country's 3.5-inch Suspension Lift. Innovative Design and Construction: When changing a vehicle's suspension, the key to preserving ride quality is keeping the geometry of all suspension components as close to their factory angles as possible. Rough Country's 3.5in lift features a set of forged aluminum upper control arms to provide the correct suspension geometry in our most durable control arm to date! This perfect-height lift is a great choice for anyone who wants more than a simple level but doesn't quite want the full height of a 6-inch option. This kit lifts and levels the front of the vehicle with the rear, offering enough increased ground clearance to run up to 295/55R20 tires with an improved, aggressive look. We didn't want to limit you to one standard kit. Rough Country's 3.5-inch kit is configurable with all the shock options that we offer. This allows you to choose which shock series you want! Ranging from our nitrogen-charged N3 shocks to our Vertex reservoir shocks the power to choose is in your hands. Installation: Requiring the use of a strut compressor to install, an estimated timeframe of 5-6 hours is recommended to complete this full installation. This full kit can be installed at home and can be completed efficiently and quickly! Limited Lifetime Replacement Warranty: Rough Country's 3.5" Suspension Lift Kit is backed with a limited lifetime replacement warranty towards manufacturer defects. As such, the product is protected from structural and workmanship damage after the date of purchase. With our industry-leading warranty give yourself peace of mind when using Rough Country's Suspension products!
