Product Details
Description
Upgrade your lifted truck’s rear axle with the Tuff Country 17757 Rear U-Bolt Kit. Designed for 4" lift setups and blocks, this zinc-plated kit provides a durable, corrosion-resistant solution to secure the axle and maintain confident handling.
- Includes four U-bolts with nuts and washers: Everything you need for a complete rear suspension reassembly—no extra parts required.
- U-bolt dimensions: 14" overall length with a 3" inside diameter and 5/8" bolt diameter to fit typical 4" rear axle tube applications.
- Finish and material: Zinc-plated steel for enhanced corrosion resistance and longer service life in harsh conditions.
- Design: Round-bend U-bolts crafted for even clamp load and secure seating around the axle tube.
- Lift-compatibility: Specifically suited for lifted vehicles using blocks, optimizing fit on 4" rear axle tube configurations.
- Brand credibility: Tuff Country’s engineering focuses on reliable, proven suspension components for a broad range of Dodge Ram and Ramcharger applications.
This U-bolt kit helps you maintain proper alignment and axle security after installation of a lift, reducing the risk of movement under load. The included hardware simplifies installation, while the zinc finish provides protection against rust and road salt, helping your suspension perform reliably over time. Ideal for replacing worn factory u-bolts or upgrading to a lift-friendly assembly.
