Product Details
Description
The Tuff Country 97007 Block & U-bolt Kit is a bolt‑on rear lift solution designed for classic 4x4s like the Chevy Blazer and GMC trucks. It delivers a 5.5-inch rear lift using tapered cast lift blocks and zinc‑plated U‑bolts, engineered to fit 1973–1991 4WD Chevy/GMC models with precision and durability.
- Lift height: Approximately 5.5 inches of rear lift from the factory position for a more commanding stance and improved clearance.
- Block construction: Heavy‑duty cast iron lift blocks (tapered design) to help minimize driveline vibration; some kits may include aluminum blocks depending on variation.
- U‑bolt hardware: Extended zinc‑plated rear U‑bolts with accompanying washers and nuts, designed specifically for Chevy Blazer and related models.
- Vehicle fitment: Rear‑only lift kit for 1973–1991 Chevy Blazer 4WD, 1973–1991 GMC Blazer/Suburban K1500 4WD, and 1973–1987/1991 Chevy/GMC 1/2‑ton trucks.
- Installation notes: Bolt‑on installation; blocks are placed between the factory leaf springs and axle, with hardware to complete the mount; not intended for front axle use.
- Shocks compatibility: For rear lifts around 5 inches, longer/shock absorbers are typically required to maintain ride quality—please consult the Shock Absorbers guidance for your application.
- Block material options: Kits may include either cast blocks or aluminum blocks, depending on the specific batch.
Designed for durability and straightforward installation, the Tuff Country 97007 kit helps you achieve a raised rear stance to accommodate larger tires and a more balanced look when the vehicle is loaded. The tapered blocks reduce driveline vibration for a smoother feel, while the zinc‑plated U‑bolts and included hardware deliver corrosion resistance and long‑lasting performance. This kit is ideal for enthusiasts restoring or upgrading 1973–1991 era Chevy Blazer and GMC 4WD pickups who want a reliable, bolt‑in solution with a clear set of components and clear usage notes. If you’re planning a taller setup (about 5 inches or more), plan to pair the kit with extended shocks to maintain proper ride and axle alignment.
