Revolution Gear & Axle Pre-89 1-Ton Swap GM 14-Bolt Dana 60 Reverse Thick 4.88 Ratio Gear Package

If you're building a heavy-duty truck for serious off-road use or towing, you're likely looking at a 1-ton axle swap. This Revolution Gear & Axle gear package is designed to help you set up a GM 14-bolt differential with a Dana 60 reverse rotation third member, giving you a robust drivetrain capable of handling larger tires and increased loads. The 4.88 ratio is a popular choice for trucks running 37-inch to 40-inch tires, providing a good balance between on-road drivability and off-road crawling power.

This kit includes all the necessary components for a professional differential rebuild, ensuring your gears mesh correctly and your differential operates smoothly. Revolution Gear & Axle is known for well-built components, and this package is no exception. You'll find precision-machined gears that are heat-treated for strength and durability, along with all the bearings, seals, and installation hardware you need to get the job done right. Setting up gears correctly is critical for longevity and performance, and using a complete, matched kit like this one takes much of the guesswork out of the process.

When undertaking a 1-ton axle swap and differential rebuild, it's important to have all your parts ready. This package aims to provide that, but always double-check your specific axle configuration to ensure compatibility with the Dana 60 reverse rotation third member. Proper installation, including careful pattern checking and backlash adjustment, is key to achieving the full benefit of these gears and ensuring they last for many miles to come.
