Suspension Lift Kits

Description

Strike the Perfect Balance: Not too tall, not too small-Rough Country's 3.5" Lifted Knuckle Kit delivers the ideal blend of aggressive looks, enhanced ground clearance, and everyday drivability. Whether you're hitting the trails or cruising the highway, this all-inclusive lift kit gives your vehicle a bold stance and the performance to match. Advanced Suspension Engineering: This kit features precision-engineered lifted knuckles that retain your factory suspension components for dependable, hassle-free installation. Unlike standard kits that can expose your CV axle boots to stress and wear, Rough Country's knuckle design repositions the CV axle for improved clearance from the lower control arm-dramatically reducing boot fatigue and protecting your drivetrain. Factory Rake Eliminated: Achieve a commanding, level profile with a front-to-rear stance that eliminates the factory rake. This not only enhances aesthetics but also improves your vehicle's balance for confident handling on and off the road. Built to Go the Distance: Fabricated rear lift blocks outlast cast alternatives with superior strength and corrosion resistance. Whether you're tackling rocky trails or hauling gear, these rugged components are made to endure. Tailored Ride Performance: This kit includes Rough Country's premium N3 shocks-10-stage variable valving, nitrogen-charged for the perfect fusion of off-road performance and on-road comfort. Want more? It's fully configurable with Rough Country's full lineup of shocks and struts, including the high-performance Vertex reservoir upgrade. Peace of Mind Included: Rough Country backs this kit with a Limited Lifetime Replacement Guarantee, ensuring your suspension is ready for whatever comes next.
