Description
Best of Both Worlds. With a 3.55 gear ratio and 30-spline pinion, this Motive 8.8" Rear Ring Gear and Pinion Kit takes the middle ground between a great racer and a standard vehicle. This ring and pinion set is perfect for the rig you want to soup up, but not totally gut as an off-road race vehicle.
Perfect Fit. It's a good idea to switch out your ring gear and pinion set if you're going to modify your vehicle. If your set doesn't match your tire size or intended vehicle purpose, then some of your engine torque and response will be lost in the mismatched mechanism. If you're upping your Ford F-150's performance, consider switching to a Motive 8.8" Rear Ring Gear and Pinion Kit.
Tough and Durable. You want your ring gear and pinion set to stand the test of wear and tear as well as the test of the off-road vehicle. Fortunately, the Motive 8.8" Rear Ring Gear and Pinion Kit is made strong and hardy from thick, 8620 steel.
Installation Note. Installing ring gear and pinion sets can be advanced work. It's highly recommended that you leave this installation to the professionals.
Warranty. Motive honors a one-year or 50,000-mile warranty on their 8.8" Rear Ring Gear and Pinion Kits with 3.55 Gear Ratio.
Application. The Motive 8.8" Rear Ring Gear and Pinion Kit with 3.55 Gear Ratio was designed to fit 1997-2014 Ford F-150 models.

Great gears for running 37s
These gears are a true 4.555 with 9 pinion splines and 41 ring splines. They provide much better acceleration during my tire swap from 33s with 3.73 gears to 37s with these 4.56 gears. One thing worth mentioning is that not included in this set is a trimmed carrier pin for your differential which means the stock carrier pin will not slide in as the ring gear obstructs it. You will either need to but a trimmed pin or do what I did and grind down one side of your pin, which will ultimately allow it to fit and not change your diffs dynamics as the surface ground down is not actually contacting the ends of your axles if setup properly.
