Revolution Gear & Axle 86-89 Toyota V6 Gen4 Pickup/Gen1 4Runner 8in Koyo 4.56 Ratio Gear Package

Revolution Gear & Axle is known for providing well-built drivetrain components, and this 4.56 ratio gear package for your 1986-1989 Toyota V6 Gen4 Pickup or Gen1 4Runner is a prime example. If you're looking to change your differential gearing, perhaps to better suit larger tires or to bring your RPMs back into a more comfortable range on the highway, this package is designed to get the job done right. The 4.56 ratio is a popular choice for vehicles running 33-inch to 35-inch tires, offering a good balance between off-road performance and on-road drivability.

This package centers around a 4.56 gear ratio, which means the ring gear will turn 4.56 times for every one turn of the pinion gear. This effectively multiplies your engine's torque to the wheels, which is crucial for getting heavier vehicles moving or for maintaining speed on inclines. Inside this kit, you'll find a full set of Koyo bearings. Koyo is a well-regarded manufacturer of bearings, known for their durability and smooth operation, which are essential for the longevity and performance of your differential. A complete gear installation package like this typically includes all the necessary bearings, races, seals, and shims needed for a proper differential rebuild, ensuring that all components work together seamlessly.

When undertaking a gear change, it's important to have all the correct parts on hand. This kit aims to provide that, but always refer to the manufacturer's installation instructions for specific details regarding setup, backlash adjustment, and break-in procedures. Proper installation and break-in are critical for ensuring the new gears mesh correctly and last for many miles to come.
