Product Details
Description
The Tuff Country 97001 4" Rear Block & U-Bolt Kit is a purpose-built upgrade for Chevy/GMC 4WD trucks and SUVs, delivering a precise four-inch rear lift while preserving ride quality.
- Lift Height: Adds a full 4" rear lift to your vehicle for improved clearance and a bolder stance.
- Block Material: Heavy-duty cast blocks (kit may include cast or aluminum blocks) with a tapered design to minimize driveline vibration and maintain a smooth ride.
- U-Bolts: Extended zinc-plated rear u-bolts sized to fit Chevy/GMC rear suspensions for secure, corrosion-resistant mounting.
- Installation: Simple bolt-on installation by inserting the lift blocks between the factory rear leaf springs and axle; includes all necessary hardware.
- Shocks Compatibility: For rear blocks at 4" high, most applications require extended-length shocks to maintain proper handling and travel. See your shock options in the Shock Absorbers section.
- Vehicle Fitment: Designed for rear axles only; suitable for 1969–1972 Chevy and GMC 4WD models, including Blazer, Suburban, and Truck variants (K1500/K2500 families).
- Tapered Design: Tapered blocks help reduce driveline vibrations and contribute to a steadier, more predictable ride.
- Corrosion Resistance: Zinc-plated u-bolts provide improved durability in demanding conditions and exposure to road elements.
Designed specifically for rear-axle applications, this kit brings a practical 4" lift with a factory-like feel. It’s a smart choice for Chevy/GMC owners looking to gain ground clearance, accommodate larger tires, or level the stance while maintaining dependable performance and durability.
