Built for classic Chevy and GMC truck owners who want to reclaim their truck's stance and off-road capability, this 4" Rough Country lift kit transforms your '69–'72 C10, K10, C15, or K15 with increased ground clearance and aggressive presence. The kit pairs application-specific front leaf springs with rear lift blocks and premium N3 shocks, clearing up to 35" tires while preserving proper driveline geometry for a smooth, balanced ride.

What's included

  • 4" Front Lifted Leaf Springs (pair) — Application-engineered for your truck's model and year, delivering increased ground clearance without sacrificing ride quality or control.
  • N3 Shock Pair (front and rear) — Premium shocks valved for your exact application, featuring 10-stage variable valving, high-pressure nitrogen charge, and durable 54mm body with 18mm piston rod for on-road smoothness and off-road capability.
  • 4" Rear Lift Blocks — Maintain proper geometry and ensure a smooth, factory-like ride after installation.
  • Brake Line Relocation Brackets — Preserve proper clearance and brake-line routing under the new suspension geometry.
  • U-Bolts and Hardware — All fasteners and clamps needed for a complete installation.
  • Installation Kit — Application-specific brackets and hardware for secure, correct fitment to your Chevy or GMC frame.

Important notes

  • If your vehicle is equipped with a front sway-bar, drop brackets are recommended (Rough Country SKU 1019) to maintain proper suspension geometry and handling.
  • Verify backspacing on 35" tires to avoid rubbing; larger tires may require wheel-offset adjustments.
