  • Lift Height: 6" front / 6" rear lift, designed to accommodate up to 35" tires (35x12.5" recommended).
  • Upper Control Arm Drop: Drops the upper control arms to improve steering geometry and suspension articulation at height.
  • One-Piece Sub-Frame: Increased strength with reduced squeaks and rattles for a quieter, more confidence-inspiring ride.
  • Rear Leaf Springs: Integrated rear springs provide reliable load support and ride consistency under lift conditions.
  • Shocks: Not included; factory length shocks must be replaced with extended shocks to install properly.
  • Wheel/Rim Compatibility: Factory rims will not fit; use rims with 4.5" backspacing or less for proper fitment.
  • Installation: Bolt-on design for a straightforward install with common hand tools and minimal downtime.
  • Warranty: Supported by a limited lifetime warranty for long-term peace of mind.
  • Brand Advantage: Crafted by Tuff Country, a trusted name with 25+ years of suspension expertise and dedicated customer support.

This kit is engineered to deliver both capability and value: it increases ground clearance and tire compatibility (up to 35" tires) while maintaining chassis integrity through a strengthened sub-frame and optimized front-end geometry. The result is a more capable truck for off-road adventures and a more commanding street presence, without sacrificing daily drivability. Plan for extended shocks and compatible rims to complete the build and enjoy a dependable, lifted 1988–1998 Chevy/GMC K1500 experience.
