Product Details

This leaf spring axle U-bolt kit is built to clamp the leaf spring assembly securely to the axle housing, helping maintain proper rear suspension location and clamping force. Dorman 929-763 is a direct-fit, standard replacement part for vehicles that require a round-bend rear U-bolt configuration.

Common Problems This Part Can Address

• Loose or weakened leaf spring-to-axle clamping
• Corrosion or damage on existing rear U-bolts
• Suspension noise from worn mounting hardware
• Rear axle movement caused by compromised fasteners
• Service replacement for round-bend leaf spring U-bolt applications

Installation Notes and Tips

Verify leaf spring dimensions, axle tube shape, and round-bend application details before installation. Confirm inside length, inside width, thread diameter, and thread length against the original hardware to ensure proper fit. Because this is a specific-fit rear suspension component, match the vehicle year, make, model, and suspension configuration before ordering. Part number 929-763 should be installed according to the vehicle service procedure and torqued to specification after the suspension is assembled.

Quality Assurance

Dorman manufactures this kit as a standard replacement suspension hardware solution for the listed applications. The steel construction, Grade 5 bolt rating, and fine-thread design support consistent fitment on the specified rear leaf spring axle mounting points.
