Description
Added Height and Off-Road Performance on Your Truck. The elevation that the Rough Country 3.50-Inch Suspension Knuckle Lift Kit gives your truck will make off-road driving a comfortable and exciting experience. This kit is made to accommodate 33 x 11-inch tires, and both stock and aftermarket wheels measuring from 17 inches to 20 inches in diameter. The kit also comes with lifted knuckles, lift blocks that perform better than stock cast blocks, and Rough Country’s own N3 rear shocks. There’s no better formula for fun driving on rocky, bumpy trails.
Includes Rough Country’s Premium N3 Shock Absorbers. One key addition to this suspension kit is Rough Country’s popular N3 shock absorbers. The company employs 10-stage variable valve, high-pressure, and nitrogen-charged shock absorbing technology. The top-quality shocks protect your truck from strong vibrations, ensuring a smooth and safe ride all throughout.
Lifted Knuckle Design for Easy Clearance. The suspension kit’s two knuckles help make the best of your truck’s lift, and optimize their connections to the two upper arms’ ball joint angles. This grants your vehicle maximum clearance over any surface obstacles on the road, and puts an end to rough and dizzying rides.
Superior Lift Block and Strut Spacer Components. Rough Country’s suspension knuckle lift kit includes fabricated lift blocks and strut spacers. These quality components are made to even out your truck’s suspension, resist wear and tear, and keep the whole setup from coming apart.
Some Cutting and Grinding Needed for Proper Installation. Ask for some professional help before you go about installing the Rough Country 3.50-Inch Suspension Knuckle Lift Kit onto your Sierra 1500. A degree of cutting and grinding is needed to ensure proper fitment onto your vehicle. Rough Country also encourages customers to get an alignment as soon as possible after lifting the truck, to prevent unnecessary burden to the truck’s tires.
Comes With a Lifetime Replacement Warranty. Rough Country Suspension Systems offers a lifetime replacement warranty on most suspension products. All products are warranted to be free from defects in material and craftsmanship for the life of the vehicle if utilized in accordance with the manufacturer’s instructions for installation and operation of said products.
Application. This Rough Country 3.50-Inch Suspension Knuckle Lift Kit fits all 4WD 2014-2018 GMC Sierra 1500 models. The kit is compatible with the vehicle’s factory cast steel control arms, and will not work with aftermarket control arms.
