Revolution Gear & Axle 00-10 Ford F-150 F9.75L-F8.8R Timken 4.56 Ratio Gear Package

If you're looking to change your Ford F-150's differential gear ratio, this package from Revolution Gear & Axle is a solid choice. This kit is designed to swap your F-150's rear differential to a 4.56 ratio, which is a popular choice for owners who have added larger tires or plan to tow frequently. A lower gear ratio like 4.56 helps bring your engine RPMs back into a more efficient range at cruising speeds, improving acceleration and reducing strain on the drivetrain when carrying heavy loads.

This package includes everything you need for a complete differential gear installation. You'll get a set of 4.56 ratio ring and pinion gears, along with a full installation kit featuring high-quality Timken bearings and races. Timken is well-known for making durable drivetrain components, so you can trust these bearings to handle the demands of your F-150. The kit also contains all the necessary seals, gaskets, shims, and hardware to ensure a proper and leak-free installation. Revolution Gear & Axle sources quality components to create a comprehensive package that saves you time and hassle compared to buying each piece separately.

Proper installation of a gear set requires precision and specific tools, including a dial indicator and gear marking compound to set backlash and pattern. If you're not experienced with differential work, it's highly recommended to have a professional mechanic perform the installation to ensure the gears are set up correctly. Incorrect installation can lead to premature gear wear or failure. This package is designed for the Ford 9.75 inch Sterling rear axle and the 8.8 inch front axle found in F-150 models from 2000 to 2010.
