Revolution Gear & Axle 79-85 Toyota 4Cyl Gen3 Pickup 8in Koyo Bearing 4.88 Ratio Gear Package

If you're looking to change the gear ratio in your 1979-1985 Toyota 4-cylinder pickup, this 4.88 ratio ring and pinion gear package from Revolution Gear & Axle is a solid option. This package is specifically designed for the 8-inch rear differential found in those trucks and includes high-quality Koyo bearings, which are well-known for their durability and smooth operation. Changing your gear ratio can make a big difference, especially if you've added larger tires or plan to tow. A lower ratio like 4.88 helps bring your engine's RPMs back into an optimal range for better acceleration and fuel efficiency at cruising speeds.

Revolution Gear & Axle puts together these kits with precision in mind. The ring and pinion gears themselves are manufactured to meet strict tolerances, ensuring a proper mesh with your differential. The inclusion of Koyo bearings means you're getting a well-built set of bearings that can handle the increased load and heat generated by a differential. This package is designed to be a complete solution for re-gearing your rear differential, making the job more straightforward. You'll want to ensure you have the proper setup tools and a service manual for your specific truck to get the backlash and pattern set correctly during installation.

When you're diving into a differential rebuild or re-gear, having all the necessary components in one package simplifies the process. This kit focuses on the core components needed for the gear change, including the ring and pinion gears and the essential Koyo bearings. Remember that a differential gear change often requires specialized tools for setting gear mesh and backlash, so be sure you're prepared or plan to have a professional mechanic handle the installation to ensure it's done right.
