Parts & Accessories Spare parts For sale: 6-stud rear differential. The differential is distinguished by its large size, 9.5 inches, similar to the size of 8-stud differentials. It fits Tahoe, Yukon, Silverado, and Sierra models from the 90s. Ring gear size 12/41 (3.42), very very clean. It only needs a front seal and parking brake cables, and your motor will be on it. Price: 1200. My location is Riyadh, Diriyah, and installation is available if you want, God willing.
