- Shocks included: SX8000 shocks are included to deliver reliable damping and ride quality across varied terrains.
- Steering arm: Steering arm included to maintain proper geometry and steering response after the lift.
- Noise reduction: Teflon pads used to minimize squeaks and ensure quiet operation over time.
- Bushings: Polyurethane bushings included with springs for durable, responsive movement and longevity.
- Installation note: Factory shocks must be replaced with extended shocks to install properly; choose extended shocks and boots in the Options if you haven’t already.
- Warranty: Backed by a limited lifetime warranty on lift kits for ongoing peace of mind.
- Fitment scope: Designed for 1988–1991 4WD Chevys and GMCs (Blazer, Suburban K1500, Jimmy); diesel engine models are not supported, and it fits 1/2-ton models.
This kit enables a practical upgrade path: gain ground clearance for rough roads and light trails, accommodate up to 33" x 12.5" tires with the right backspacing, and preserve or improve load-carrying capabilities with heavy-duty springs and polyurethane bushings. The included SX8000 shocks, along with the front and rear springs and steering arm, deliver a balanced ride that’s better suited to real-world use—whether you’re tackling winter trails, hauling gear, or welcoming aftermarket bumpers. With Tuff Country’s 35+ years of suspension expertise and a lifetime warranty, you get a dependable, value-driven upgrade that stands up to daily driving and weekend adventures alike.
