Product Details
Description
The Tuff Country 97021 Block & U-Bolt Kit is a bolt-on rear lift solution designed for Chevy Silverado 2500HD and GMC Sierra 2500HD 4WD pickups. It raises the rear by 1 inch while preserving a factory-like ride, making it ideal for towing, hauling, or achieving a balanced stance.
- Lift Height: 1" rear lift to level or subtly enhance the rear against the factory ride
- Block Material: Heavy‑duty cast iron lift blocks with precise, non‑tapered geometry
- Block Dimensions: 1" (H) x 2 1/4" (W) x 6 1/2" (L)
- U-Bolts: Zinc‑plated extended rear u-bolts designed specifically for the Chevy Silverado 2500HD 4WD
- Hardware Included: Necessary mounting nuts and washers for a complete bolt-on install
- Vehicle Fitment: 2001–2010 Chevy Silverado 2500HD 4WD and 2001–2010 GMC Sierra 2500HD 4WD
- Installation: Simple bolt‑on installation; lift blocks insert between the factory rear leaf springs and axle
- Shocks Compatibility: Note: On most applications, factory length shocks must be replaced with extended length shocks when installing rear blocks 2" in height or taller
- Corrosion Resistance: Zinc plating provides durability and corrosion resistance for long‑lasting performance
- Rear‑Only Design: Designed for rear axles only; not intended for front axles
This kit is built to maintain a smooth, factory-like ride while giving you a reliable 1" rear lift. Cast lift blocks paired with hardened, zinc‑plated u‑bolts deliver dependable support for daily driving and heavier loads. If you’re upgrading for towing or payload management, this kit helps reduce rear sag and enhances overall stance without drastic changes to handling.
