Product Details

This Dorman leaf spring axle U-bolt kit is built for leaf spring-to-axle attachment where the axle must be clamped securely to the spring pack. The 9/16 in. fine-thread design, 3.5 in. thread length, and standard replacement grade make it a practical choice for suspension work on older Ford trucks and SUVs, including Ford F-250, Ford F-350, and Ford Excursion applications listed in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part number 929-749 is also referenced as a direct replacement option for related suspension service needs.

Common Repair Uses

• Loose or worn leaf spring axle clamping hardware
• Suspension noise from degraded U-bolt retention

Installation Notes

Verify leaf spring dimensions, inside width, inside length, thread diameter, and thread type before ordering. Confirm the axle and spring pack configuration against the vehicle listing, including front or rear position and any square-bend notes. For best results, replace suspension hardware in matched sets when the application calls for it and torque fasteners to the vehicle manufacturer’s specification.
