Revolution Gear & Axle 89-98 1-Ton Swap GM 14-Bolt Dana 60 Koyo Bearing 5.13 Ratio Gear Package

This Revolution Gear & Axle package is built for 1-ton truck owners performing a GM 14-bolt to Dana 60 axle swap on 1989-1998 GM trucks. It provides a 5.13 gear ratio, which is a common choice for significantly larger tires, helping to bring your engine's RPM back into a more efficient range. This kit includes everything you need to properly set up your new differential, ensuring smooth and reliable power delivery to the wheels.

At the heart of this package are the Koyo bearings, known for their well-built construction and consistent performance. Koyo is a respected name in drivetrain components, and their bearings are designed to handle the stresses of heavy-duty applications. The 5.13 ratio is a substantial change from stock, so it's ideal for vehicles running 37-inch tires or larger. This ratio helps compensate for the increased tire diameter, preventing the engine from lugging and improving drivability. The gears themselves are precision-cut to ensure proper meshing and quiet operation, which is crucial for a comfortable driving experience.

When undertaking an axle swap and differential rebuild, proper setup is critical. This kit includes the necessary installation hardware and bearings to get the job done right. While this package contains the core components for your gear change, remember that setting gear backlash and pattern correctly requires specialized tools and knowledge. If you're not experienced with differential setup, it's always best to consult a professional mechanic to ensure your new gears are installed to manufacturer specifications for optimal performance and longevity.
