Revolution Gear & Axle 86-89 Toyota V6 Gen4 Pickup/Gen1 4Runner 8in Koyo 4.88 Ratio Gear Package

If you're looking to fit larger tires on your 1986-1989 Toyota V6 Gen4 Pickup or Gen1 4Runner, changing your differential's gear ratio is a smart move. This complete gear package from Revolution Gear & Axle includes everything you need to install a 4.88 ratio into your 8-inch rear differential. A 4.88 ratio is ideal for vehicles running 33-inch to 35-inch tires, bringing your engine's RPMs back into a more efficient range and improving acceleration that can be lost with larger rubber.

This package features high-quality Koyo bearings, which are well-known for their durability and smooth operation. Revolution Gear & Axle has put together this kit to ensure you have all the necessary components for a successful differential rebuild. You'll find precision-cut ring and pinion gears designed for optimal meshing and quiet operation. This isn't just a set of gears; it's a comprehensive solution to properly re-gear your drivetrain for improved performance with larger tires.

When you're tackling a differential gear change, it's important to have all the right parts. This kit aims to provide that completeness, but remember that proper installation is key. You'll want to ensure you have the correct tools and a service manual for your specific Toyota model to set the backlash and pinion depth correctly. Taking the time to do this right will result in a quiet, reliable, and well-performing differential for years to come.
