- Tire Compatibility: Ready to run up to 33" x 12.5" tires for enhanced traction and a roomier wheel‑well look.
- Installation Notes: Requires replacement of factory shocks with extended shocks for proper installation; shocks and boots can be added in the Options field if needed.
- Warranty: Backed by Tuff Country’s limited lifetime warranty, reflecting the brand’s commitment to long‑term reliability.
- Fitment & Range: Specifically designed for 1988–1991 Chevy Blazer 4WD, Suburban K1500 4WD (gas engines, 1/2 ton), and 1988–1991 GMC Jimmy 4WD / Suburban K1500 4WD (gas engines, 1/2 ton); diesel models are not supported.
This lift kit transforms daily driving and weekend adventures by delivering a balanced, capable 3" lift, solid front/rear springs, and proven SX8000 shocks that work together to improve ground clearance, tire compatibility, and overall ride quality.
