Ford Racing 3.73 Gears (8.8in Rear)

Ideal 3.55 Upgrade. Whether your F150 came standard with 3.55 or 3.73 gears from the factory, Ford Racing's 3.73 gears are a great step up in performance and durability. If you're going from 3.55s, you'll enjoy more low-end torque - exactly the reason premium packages like the Harley Davidson and King Ranch had 3.73s from the factory.

Ideal Durability Upgrade. Upgrading existing 3.73 gears? Trust Ford Racing's legendary quality - these gars 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.

One Stop Shop. For your convenience and peace of mind, we offer either an installation kit or a master bearing installation kit that will help you get the most out of your gears (first drop down above). Master bearing kit recommended by most installers, especially those with higher mileage. Also, you can save some cash during installation and have your Trac-Lok rebuilt at the same time as your gears are installed (see second drop-down menu above).
