Product Details
Description
The Tuff Country 16731KN 6" Lift Kit delivers a true 6-inch rise for GM 4x4s with a focus on ride quality and reliability. Built for off-road enthusiasts who want a capable, hakey-free lift, it combines proven EZ-Ride springs with durable SX8000 shocks for a balanced, confident ride.
- Lift height: 6" suspension lift designed to accommodate larger tires while preserving steering geometry and overall stability.
- EZ-Ride front springs: advanced leaf-spring design to improve ride quality and handling over rough terrain.
- 52" rear springs: longer rear packs to enhance axle articulation and load support on trails and daily driving.
- Rear blocks: well-engineered blocks to maintain proper axle position after lifting and to support heavy loads.
- SX8000 shocks included: rugged dampers that deliver controlled damping and responsive handling on and off the pavement.
- Steering arm: factory-accurate steering linkage component to help preserve steering feel at height and during articulation.
- Complete hardware: includes all necessary mounting brackets, U-bolts, washers, and fittings for a straightforward installation.
- Warranty: backed by a limited lifetime warranty on leaf springs and the kit, reflecting Tuff Country’s commitment to long-term performance.
- Install time: average 5–7 hours to complete, depending on vehicle condition and tooling availability.
- Vehicle fitment notes: designed for 1988–1991 Chevrolet Blazer 4WD, 1988–1991 Chevrolet Suburban K1500 4WD, 1988–1991 GMC Jimmy 4WD, and 1988–1991 GMC Suburban K1500 4WD. Fits 1/2-ton models and will not fit diesel engine variants.
This lift kit is built to unlock serious off-road capability without sacrificing everyday usability. The EZ-Ride springs and teflon pads minimize road noise and squeaks, while the 35" tire compatibility (as recommended) gives you the aggressive stance and traction needed for rocky trails or mud runs. The included steering arm and proven rear suspension components maintain predictable handling, so you can push limits with confidence on your next adventure.
