What It Helps Address

• Loose or damaged leaf spring-to-axle clamping hardware
• Corrosion or fatigue in existing U-bolts
• Suspension noise caused by worn fastening components
• Loss of clamping force at the spring pack and axle interface
• Replacement needs during leaf spring or axle service

Installation Notes and Tips

Verify leaf spring dimensions, inside length, inside width, thread diameter, and thread length before ordering. Confirm whether your application uses a front or rear position and a round-bend U-bolt layout. Match the vehicle year, make, model, and suspension configuration exactly, since this kit is specific fitment rather than universal. For best results, inspect the spring plates, axle seat, and related hardware during installation.

Quality Assurance

Dorman supplies standard replacement suspension hardware for specific vehicle applications, and this kit follows the listed dimensions and Grade 8 specification for the intended fitment. Use the confirmed vehicle and measurement data to select the correct part for your Ford Bronco, Chevrolet Blazer, Chevrolet K10, or GMC Jimmy application.
