Product Description

The Rancho RS720 is a front axle leaf spring U-bolt kit designed specifically for 1987-1995 Jeep Wrangler YJ models running Rancho suspension systems at 2.0 to 2.5 inches of front lift. The kit contains four high-strength zinc-plated steel round U-bolts in two application-specific sizes - two narrower units and two wider units - along with all required hardware. The precise sizing ensures correct clamping force and proper axle-to-spring alignment when paired with Rancho leaf spring packs in the specified lift range, and the zinc plating delivers corrosion resistance for long service life in demanding off-road conditions.

These U-bolts are engineered exclusively for use with Rancho suspension systems and should not be substituted into other brands' suspension setups. After the initial 100 miles of driving and following every off-road use, all U-bolts should be inspected and retorqued to the manufacturer's specified values to maintain proper clamping force. For 1972-1986 Jeep CJ5, CJ6, CJ7, and CJ8 front axle applications, refer to Rancho RS712.
