Review: Great quality - Super impressed with this gear set. I usually only use AAM gears for rebuilds but they don't offer a 4.56 that I needed for my personal truck. I gave this inexpensive set a shot expecting it to give me trouble setting it up and or noisy. Much to my surprise, it setup perfect first try with the original .037" pinion shim. With the backlash at .007" the pattern looked good and it's as quiet as can be. Review: Sent USED GEARs - I got used gears that were installed and showed signs of wear. Prepared a whole weekend to do the task and it got ruined ## Features - ✅ Motive Gear 4.56 Ring & Pinion – Precision-engineered for GM 8.5"/8.625" 10-bolt differentials, delivering increased torque, strength & smooth performance for daily & high-performance vehicles. - ✅ Premium 8620 Steel Construction – Heat-treated for exceptional durability, wear resistance & longevity, ensuring reliability under heavy loads & extreme conditions. - ✅ OE Direct Fit & Simple Installation – Designed for a seamless fit, works with 2.73+ carrier ratios, replaces OE components with precision machining for factory-like performance & easy installation. - ✅ Compatible with GM Vehicles (1970-2020) – Fits Chevrolet, GMC, Cadillac, Buick, Pontiac & Oldsmobile models, including Silverado, Tahoe, Yukon, Escalade, Camaro, Impala & more—verify fitment details. - ✅ Replaces American Axle 40028640, Richmond Gear 69-0167-1, Motive Gear GM10-456, EXCEL from Richmond GM85456. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001P2CI66 | | Best Sellers Rank | #136,551 in Automotive ( See Top 100 in Automotive ) #12 in Automotive Replacement Differential Rings & Pinions | | Brand | Motive Gear | | Customer Reviews | 3.7 3.7 out of 5 stars (31) | | Date First Available | January 5, 2009 | | Exterior | Machined | | Item Weight | 18.26 pounds | | Item model number | GM10-456A | | Manufacturer | Motive Gear | | Manufacturer Part Number | GM10-456A | | Model | Motive Gear GM10-456A Differential Ring and Pinion | | OEM Part Number | GM10-456A | | Product Dimensions | 15.5 x 11 x 5.25 inches | ## Images ![Motive Gear GM10-456A Diff.
