    Precise Calibration. You can be sure of getting the right gears in line when using the Richmond 9.25 in. Rear Ring Gear and Pinion Kit - 3.91 Gears in your truck transmission system.

The kit is made using the latest engineering processes and has been heat-treated through a computer-controlled system. Its 8620 steel construction makes sure that it is tough and rigid enough to stay in form throughout its lifespan.

    Warranty. This Richmond 9.25 in. Rear Ring Gear and Pinion Kit - 3.91 has a warranty that is twice as long as other Richmond gear kits. This kit comes with a two-year or 100,000-mile warranty.
