Application Details

This Dorman leaf spring axle U-bolt kit, part number 929-711, is built for rear suspension use where the leaf spring assembly must be clamped securely to the axle. It is listed for square-bend rear applications on classic GMC Jimmy and Chevrolet Blazer platforms, including 1970-1988 GMC Jimmy rear, 1969-1974 Chevrolet Blazer rear, 1987 Chevrolet Blazer rear, 1975-1986 Chevrolet K5 Blazer rear, 1969-1972 Chevrolet K10 Suburban rear, and 1969-1972 Chevrolet K20 Suburban rear. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Loose or worn leaf spring-to-axle clamping
• Corrosion-damaged U-bolts on rear suspension assemblies
• Incorrect U-bolt dimensions during leaf spring service
• Reduced clamping force at the axle mount
• Replacement needs for square-bend rear leaf spring setups

Installation Notes

Verify leaf spring dimensions, inside length, inside width, thread diameter, and thread length before installation. Confirm the rear axle and spring pack configuration matches the listed application, especially on GMC Jimmy and Chevrolet Blazer models. Replace hardware in matched suspension service when the existing U-bolts show stretching, rust, or thread damage.

Quality Assurance

Dorman standard replacement suspension hardware is built to match the listed application requirements and dimensional specifications for direct-fit service on confirmed vehicles.
