Installation Notes

Measure the leaf spring dimensions and confirm axle tube size before installation. Match the inside width, inside length, thread diameter, and thread length to the original hardware specification.

Because this is a specific-fit part, application verification is important before installation on Chevrolet Silverado, GMC Sierra, or other leaf spring axle setups.
