Revolution Gear & Axle 89-98 1-Ton Swap GM 14-Bolt Dana 60 Koyo Bearing 4.88 Ratio Gear Package

This Revolution Gear & Axle gear package starts with a 4.88 gear ratio, designed for 1-ton truck swaps using the GM 14-bolt and Dana 60 differentials. The 4.88 ratio is a popular choice for trucks that have been modified with larger tires, helping to bring the engine's RPM back into its optimal power band for better acceleration and drivability. This kit is specifically for 1989-1998 GM 1-ton applications, ensuring a direct fit for those specific axle configurations.

Inside this comprehensive package, you'll find genuine Koyo bearings, known for their smooth operation and long service life. Koyo is a well-respected name in bearing manufacturing, and their inclusion means you're getting a solid foundation for your differential rebuild. The gears themselves are precision-cut to ensure proper meshing and minimal noise, which is crucial for a quiet and efficient drivetrain. This kit is intended for a complete differential overhaul, providing the essential components needed to replace worn or damaged gears and bearings, or to re-gear for a different tire size.

When undertaking a differential gear swap, it's important to have all the necessary installation components. This package includes the critical gears and bearings, but you'll also want to ensure you have fresh gear oil, RTV sealant for the differential cover, and potentially a new gasket if your cover doesn't reuse the old one. Proper setup and backlash adjustment are key to a successful gear installation, so having a service manual for your specific axle is highly recommended. This Revolution Gear & Axle package is a well-built solution for those looking to upgrade or rebuild their 1-ton truck's differential with quality components.
