Product Details
Description
Tuff Country 27853 Rear U‑Bolt Kit provides a robust, corrosion‑resistant solution for securing rear blocks on 2"–4" lift setups. Designed for stock height or lifted suspensions, it’s ideal for tough, daily-driven 4WD GMC trucks and heavy‑duty applications.
- Kit contents: Includes four U‑bolts with nuts and washers for a complete installation
- Material & finish: Zinc‑plated steel to resist corrosion in wet, salty, and off‑road conditions
- Dimensions: 1/2" bolt diameter; inside diameter 2 3/4"; length 9 7/8"; round bend
- Installation compatibility: Fit stock‑height vehicles or those using rear blocks/add‑a‑leafs for 2"–4" lifts
- Application: Specifically designed for lifted 4WD GMC models, including classic GMC Suburban/K2500 and GMC Truck platforms
Replacing worn or damaged U‑bolts with this kit helps restore secure rear axle mounting, maintains proper axle position under load, and supports reliable ride quality after lifting or block installations. The included hardware simplifies the process, and the durable zinc finish extends service life in challenging driving conditions.
