      Description

      Incredible Power and Performance. Expand your Ford F-150’s capability with this 5.13 ratio Nitro Gear & Axle 8.8 in. Rear Ring Gear and Pinion Kit. It’s the perfect kit to use for those power hogging driving conditions or towing operations. That’s because it has been designed to more efficiently transform power from the truck’s engines to the wheels. Indeed, this ring gear and pinion kit increases torque and speeds up acceleration like no other.

      High-Quality Steel Construction. These Ring and Pinion gears are made from premium-quality 8620 steel which has been CNC-cut using a computer controlled technique. Additionally, to ensure reliable and smooth operation, these gears have been heat treated, CNC triple lapped, and Rockwell tested.

      Recommended Upgrade. Changes to the gear ratio of your Ford F-150’s differential may cause the speedometer to display inaccurate speed. However, this can be easily fixed with a handheld tuner (not included).

      Note on Installation. Installing these Ring and Pinion gears involves an intricate process. We recommend the help of a highly qualified professional to ensure proper installation.

      2-Year Warranty Coverage. This Ring and Pinion gear kit is backed by Nitro Gear & Axle’s two-year warranty which covers defects in structural workmanship. Some limitations may apply.

      Application. This 5.13 ratio Nitro Gear & Axle 8.8 in. Rear Ring Gear and Pinion Kit fits all 1997-2009 Ford F-150s with an 8.8" (10 bolt) rear suspension differential. We recommend the use of a master bearing kit, especially on high mileage trucks.

      Please Note. Get in touch with your local Ford dealer to find out if your F-150 has an 8.8 in. (10 bolt) or a 9.75 in. (12 bolt) differential.

      Technical Note. Matching both the front and rear gear ratios on Ford F-150 four-wheel-drive models is required to prevent damage to both the transfer case and transmission. We recommend working with a qualified shop that you trust to ensure proper installation.
