      Description

      Improves Performance. Motive's Stock Performance 3.55 Ring and Pinion Gears are a great way to get your heavy weight F-150 up and moving faster. By upgrading to a steeper set of rear gears your F-150 will enter into its power band sooner for an increase in low end torque and quicker acceleration. A set of 3.55 Motive Gears are ideal for all drivers who are looking to improve the performance and towing capability of their Ford F-150.

      Superior Construction. Motive Ring and Pinion Gears are CNC machined from high grade 8620 gear steel and factory lapped for a precise fit. Each set of gears are hardness tested prior to leaving the factory to ensure the highest quality possible. Unlike other aftermarket brands, Motive Gears do not have a reputation for annoying gear whine. Motive is so confident in the quality of their gears that they are backed with a 12 month, 100,000 mile warranty against defects in materials and workmanship.

      Recommended Upgrade. Please note that when changing the gear ratio of your F-150's rear differential that the calibration of your speedometer will no longer be correct and will display the wrong speed. However, you can easily fix this annoying issue with a Handheld Tuner (sold separately).

      Application. This 3.55 ratio Motive Gear Stock Performance Ring and Pinion Gear set will fit all 1997 to 2020 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.

      Motive gear are right on

      Installed these in my 06 F150 with a 6" lifts and 37" tires. This truck is fun to drive and the power now is awesome. Have a ton of torque I have over 6k on these gears and inspected with oil change and they look like OEM quality and are braking in just fine. Motive is the way to go if they have the correct ratio you need.

      Feel the Powwwaaa!!

      These gears are amazing upgrade from factory 3.73 gears! Really gets up and goes now! with lots of low end torque, great for running bigger tires and great for towing! These gears are a great alternative to Yukon Gears not only being half the price, but it has the same effect on your truck! overall I would recommend these gears for anyone looking to put a get up and go back into your truck! Lots of people say it would greatly effect gas mileage with such a high gear ratios, however in the 2-3 weeks ive had these installed ive not noticed any great reduction in fuel economy. If there is a reduction it is very minor. ( 1 mpg or so). I hope this review saved you time and wondering if cheaper gears are worth it, and im gear to say that they are!

      Does not fit 2015 Ford F-150

      This item will not fit a 2015 Ford F-150 3.5 ecoboost. Second the packaging this item came in is horrible. It was a cardboard box with paper as stuffing leaving the items to roll around and hit each other.
