This 3.55 ratio Motive Gear Stock Performance Ring and Pinion Gear set will fit all 1997 to 2017 F-150's equipped with a 9.75" (12 bolt) rear differential. A master bearing kit is recommended by most installers, especially on high mileage vehicles.Technical Note.
2011 and newer F-150s will require different Pinion Bearings and Crush Sleeves.Please Note.
If you are unsure if your F-150 has an 8.8 in. (10 Bolt) or a 9.75 in. (12 Bolt) rear, please check with your local Ford dealer to determine what rear is in your truck.
Technical Note. If your F-150 is two wheel drive, you can change your rear gears without any driveline issues. However, if your F-150 is a four wheel drive model, you will need to change both the front and rear gear ratios to match. Failure to do so will cause severe damage to both the transfer case and transmission. Installation costs will vary, but a good rule of thumb is between $250 and $300. Be sure to work with a reliable shop that you trust for installations.
