- Kit contents: Includes four U-bolts, plus nuts and washers for a complete installation.
- Diameter: 5/8" bolt diameter for robust, dependable clamping.
- Inside diameter: 2 3/4" to accommodate standard leaf-spring assemblies.
- Length: 14" overall, sized for lifted rear axles with blocks.
- Bend type: Square bend design for secure fit and easy seating around the leaf pack.
- Finish: Zinc-plated finish provides superior corrosion resistance in harsh road and weather conditions.
- Designed for lifted vehicles: Specifically engineered to work with lift blocks and higher axle positioning common on mid- and heavy-duty Chevy builds.
- Vehicle compatibility: Fits a broad range of Chevy 4WD applications from 1969–1998, including Blazer, Suburban (K1500/K2500), and 1/2–3/4 ton Chevy Trucks with rear leaf-spring suspensions.
This U-bolt kit delivers a durable, long-lasting solution to secure rear leaf springs after lifting. The zinc finish reduces corrosion from road salt and moisture, while the precise 14" length and 5/8" diameter ensure reliable clamp load across the entire spring pack. With nuts and washers included, installation is straightforward, helping you restore proper axle alignment, maintain ride height, and keep your truck’s rear suspension tight and trustworthy—whether you’re leveling a Blazer, Suburban, or Silverado/Sierra chassis equipped for a 3" lift.
