Show original supplier description
The Yukon Gear & Axle YGGM8.5-308-YG is a high-performance ring and pinion gear set engineered for GM 8.5" and 8.6" differentials, offering a 3.08 gear ratio. With an 8.50" ring gear diameter, 30-spline pinion, and 10 ring gear bolts, this gear set is built to withstand demanding conditions on the street, off-road, or at the track. Yukon designs these gears to OEM specifications, aiming for easy setup and reliable performance. The product comes with a one-year warranty. It is important to note that this specific gear set, YGGM8.5-308-YG, does not include an ABS provision on the pinion and does not have an ABS ring. It is compatible with OEM differentials that have ABS provisions, specifically mentioning use with 4-piston Impla and Caprice models, but without an ABS ring. Yukon offers a wide selection of gear ratios to optimize traction performance, whether you have added significant horsepower, upgraded to larger tires, or simply want to enhance your vehicle's performance. Their commitment to quality is further backed by the Y.E.S. Plan, a lifetime protection plan for your gear set.
