Built for classic Chevy and GMC truck owners who want a more aggressive stance with genuine off-road capability, this 4-inch lift kit raises your front and rear suspension while correcting steering geometry and making room for 35-inch tires. Rough Country pairs application-specific leaf springs with N3 series shocks to deliver a balanced ride that works both on pavement and in the dirt.

What's included

• N3 Kit Box — Rough Country's complete front and rear suspension hardware package engineered for your exact truck model.
• 4-inch Front Lifted Leaf Springs (qty 2) — Application-specific springs that increase ground clearance while preserving ride quality and maintaining proper caster angles.
• 4-inch Rear Lifted Leaf Springs (qty 2) — Optional replacement springs for a complete rear lift without relying on blocks, delivering consistent geometry and a factory-like feel.
• N3 Series Shock Absorbers — Premium, application-valved shocks with 10-stage variable valving, high-pressure nitrogen charge, and 54mm bodies designed for balanced comfort on-road and control off-road.
• Raised Steering Arm — Corrects steering geometry after the lift to restore tight, responsive handling and proper alignment.

Important notes

• Kit fits only vehicles equipped with 52-inch rear leaf springs — confirm your truck's spec before ordering.
• If your truck has a factory front sway bar, drop brackets (SKU 1019) are recommended to maintain proper geometry.
• Vehicles with factory dual front shocks (quad shocks, two per side) will use a single aftermarket shock per side — the kit accounts for this.
• Rear spring size varies by model year and wheelbase — Road Runner will confirm fitment during consultation.
• Proper wheel backspacing is required to safely run 35-inch tires; discuss offset and backspacing when you call to order.
