Revolution Gear & Axle 79-85 Toyota 4Cyl Gen3 Pickup 8in Koyo Bearing 4.56 Ratio Gear Package

When you open this box, you're getting a complete gear package from Revolution Gear & Axle designed to change the final drive ratio on your 1979-1985 Toyota 4-cylinder Gen3 Pickup. This specific kit comes with a 4.56 ratio, which is a common upgrade for trucks that see a lot of off-road use or are running larger tires. The package also includes a full set of Koyo bearings, which are well-known for their durability and smooth operation. Changing your gear ratio like this can make a big difference in how your truck performs, especially if you've added larger tires or are towing.

A 4.56 ratio means that for every 4.56 rotations of your driveshaft, your differential will turn 1 time. This is a lower (numerically higher) ratio than stock, which means your engine will turn more RPMs at cruising speed. For a 4-cylinder engine, this often translates to better acceleration and more responsive power delivery, especially off the line or when climbing hills. It can also help compensate for the added rotational mass and diameter of larger tires, bringing your speedometer closer to accurate and improving overall drivability. The Koyo bearings included are a solid choice, offering reliable performance and longevity.

This gear package is a significant upgrade for your drivetrain. It's important to have these installed by a professional or someone very experienced with differential setup, as proper gear mesh and bearing pre-load are critical for performance and to avoid premature wear. If you're looking to get more out of your Gen3 Toyota Pickup's engine, especially with modifications like larger tires, this 4.56 ratio gear set with Koyo bearings is a popular way to achieve it.
