Product Details
Description
The Tuff Country 97002 Rear Block & U-Bolt Kit provides a robust, bolt-on solution to lift the rear of select Chevy/GMC trucks by 5.5 inches, delivering added clearance with a factory-like ride. Built for rear-axle applications, it’s designed for easy installation and lasting performance from a trusted suspension specialist.
- Lift Height: 5.5 inches rear lift with a tapered block design to minimize driveline vibration
- Block Material: Heavy-duty blocks crafted from cast iron (some kits may use aluminum blocks) for durability and precise fitment
- Block Dimensions: 5.5" (H) x 2.5" (W) x 5.25" (L) lift blocks tailored to the Chevy/GMC rear suspension
- U-Bolts: Extended zinc-plated U-bolts sized 5/8" x 2-3/4" x 14" for secure, corrosion-resistant mounting
- Hardware Included: Complete kit with nuts, washers, and all necessary mounting hardware for a straightforward bolt-on installation
- Fitment: Designed for rear axles on 1969–1972 Chevy/GMC 1/2- to 3/4-ton 4WD models (Blazer, Suburban, and Truck/Jimmy lines)
- Shocks Note: In most applications, extended-length shocks are required when installing blocks 2" tall or taller
- Installation Type: Simple bolt-on installation suitable for DIY enthusiasts and professional shops alike
The kit includes tapered lift blocks and zinc-coated U-bolts that work together to maintain stability and reduce vibrations, even under load. By raising the rear, you gain additional ground clearance for off-road adventures or larger tires, while preserving a comfortable ride thanks to the precision-tuned block geometry. The zinc-plated hardware resists corrosion, helping your suspension stay reliable in challenging conditions. Remember this kit is intended for rear-axle applications only and should be paired with appropriately rated shocks to maintain optimal suspension travel and control.
