Detailed Product Description

This Dorman OE FIX wheel lug nut is engineered for vehicles that originally used a failure-prone two-piece lug nut design.

It is a practical replacement for owners searching for a wheel lug nut for 2006-2012 Chevrolet Colorado, 2006-2012 GMC Canyon, and other listed GM models that require an M12-1.50 conical-seat lug nut. This part cross-references GM OE 9596069 for the same application.
