Ideal Upgrade. If your F-150 came standard with 3.55 gears from the factory, these Ford Racing's 3.73 gears are a great step up in performance and durability. You will be able to enjoy more low-end torque - the exact reason premium packages like the Harley Davidson and King Ranch came with 3.73s straight from the factory.

Superior Quality. Whether you are upgrading from a lower gear ratio or replacing your existing 3.73 gears you can trust Ford Racing's legendary quality - these gears feature forged construction, CNC cut & lapped gear teeth, and a rust-resistant black oxide finish. These make the perfect addition to your truck's driveline.

Application. This 3.73 Ford Racing Ring and Pinion Gear set will fit all 1997 to 2014 Ford F-150's equipped with  8.8" rear differential. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see add on option above.

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. 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. You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.
