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

If you're looking to improve your Toyota's off-road capability or tow heavier loads, changing your differential gear ratio is a smart move. This Revolution Gear & Axle package is specifically for 1986-1989 Toyota 4-cylinder Pickup trucks and the first-generation 4Runner, giving you a 4.56 gear ratio for the 8-inch rear differential. A higher ratio like 4.56 means your engine will turn more times for every rotation of your wheels, which is great for getting larger tires moving or for keeping your engine in its power band at lower speeds.

This kit uses Koyo bearings, a well-known name for their durable and precise bearing manufacturing. Koyo bearings are a solid choice for this rebuild, ensuring smooth operation and long life for your differential. The package includes all the necessary components for a complete gear installation, so you can be confident you have what you need to get the job done right. Proper installation is key for this type of upgrade, and using quality parts like these from Revolution Gear & Axle will make a noticeable difference in your vehicle's performance, especially when you're tackling tough terrain or hauling significant weight.

When undertaking a gear change like this, it's important to have the right tools and follow the manufacturer's installation instructions carefully. This includes proper setup of the ring and pinion gears to ensure they mesh correctly and are broken in according to the recommended procedure. This package is designed to give your Toyota a significant boost in low-end torque, making it a popular choice for off-roaders and those who frequently tow.
