    Performance Set-Up. The ring and pinion gear set ratio in your GMC Sierra 1500 dictates the number of times the drive shaft will rotate in relation to your wheels. In the case of the Motive Performance 8.5 in. & 8.625 in. Rear Ring Gear and Pinion Kit - 2.73 Gears the 2.73 number means that your driveshaft will rotate 2.73 times to get your wheel to rotate once. This ratio is will result in lower RPMs and thus it is excellent for gas mileage, so if you are using your GMC Sierra 1500 for commuting, you will achieve higher miles per gallon than with a higher number gear set.

    Finest Quality. Constantly striving and testing for better quality and processes to manufacture their drivetrain components, Motive Gear Performance uses 8620 first run steel so that it can greatly reduce the amount of imperfections in the casting material. Once cast, these gears are precision machined and then lapped for smooth performance and quiet operation. The heat tempering, to make these gears even harder, is computer controlled to get the optimum hardness every time.

    Installation Notes. Working on your drivetrain is an involved job that requires familiarity with the system, the proper tools and equipment. If you do not have these things then it is recommended that you take this part to a certified mechanic and have them do the work.

    2 Year or 100,000 Mile Warranty.
