Product Details
Description
Lift the rear of your Chevy Silverado 1500 or GMC Sierra 1500 4WD with confidence using the Tuff Country 97030 Block & U-Bolt Kit. Designed for bolt-on installation, this kit delivers a precise 2.5" rear lift by swapping in tapered blocks and using zinc-plated extended u-bolts, engineered to maintain a near-stock ride while giving your truck a balanced stance.
- Lift Height: 2.5" rear lift (replaces factory blocks) for a balanced, level look when loaded or towing.
- Block Material & Design: Heavy-duty cast iron blocks, tapered to minimize driveline vibration and improve driveline alignment.
- Block Dimensions: 4" (H) x 2 1/2" (W) x 4 3/4" (L) blocks designed to fit the factory geometry.
- U-Bolt Kit: Extended zinc-plated rear u-bolts specifically sized for the Chevy Silverado 1500, with nuts and washers included for a secure install.
- Hardware & Fit: Complete bolt-on hardware to mount between the factory rear leaf springs and axle; designed for rear axles only.
- Compatibility: Replaces factory blocks on 1999–2025 Chevy Silverado 1500 4WD and 1999–2025 GMC Sierra 1500 4WD.
- Block Options: Kits may include CAST BLOCKS or ALUMINUM BLOCKS, with this kit featuring tapered blocks for vibration reduction.
- Installation Note: Front axles should never use lift blocks; consult the shock requirements when installing rear blocks 2" or taller.
This Tuff Country lift solution is built to deliver a solid, reliable upgrade for a wide range of model years, enhancing stance and gear-ready capability without compromising ride quality. The tapered block design and corrosion-resistant hardware help ensure long-term performance, while the bolt-on installation makes it a practical upgrade for DIY enthusiasts and professional installers alike.
