Detailed Description

Rancho RS721 is a rear leaf spring axle U-bolt kit made for Jeep Wrangler models from 1987 through 1995 with rear raised height between 2.0 in. and 2.5 in. It is used to replace damaged or fatigued U-bolts that secure the axle to the leaf spring pack, helping maintain proper clamping force in the rear suspension. This Rancho RS721 application is relevant for Jeep Wrangler owners servicing lifted rear suspension setups or replacing hardware during spring work.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues It Can Address

  • Broken or corroded rear leaf spring U-bolts
  • Loose axle-to-spring clamping at the rear suspension
  • Hardware replacement during leaf spring pack service
  • Rear suspension service on lifted Jeep Wrangler setups
  • Fitment needs for stock or aftermarket leaf spring packs

Installation Notes and Tips

Verify rear ride height and suspension configuration before ordering. This Rancho RS721 kit is listed for rear use on 1987-1995 Jeep Wrangler models with 2.0 in. to 2.5 in. rear raised height. Inspect the leaf spring pack, axle seat, and mounting surfaces for wear or damage before installation, and confirm all fasteners are torqued to the vehicle manufacturer’s specifications.

Quality Assurance

Rancho identifies RS721 as a performance-grade replacement part for suspension service. It is intended for direct replacement use in the specified Jeep Wrangler rear application and for use with stock or aftermarket leaf spring packs.
