Revolution Gear & Axle 93-10 Ford F-250 F10.25-D60RT 4.88 Ratio Gear Package

This Revolution Gear & Axle package gives you everything needed to install a new 4.88 ratio ring and pinion gear set into your 1993-2010 Ford F-250 with the Dana 10.25" (D60RT) rear differential. Changing your gear ratio is a common upgrade when you've modified your vehicle with larger tires, as it helps bring your engine's RPMs back into their optimal operating range at cruising speeds. This means better performance and improved fuel economy compared to running stock gears with oversized tires.

Inside this kit, you'll find a well-built ring and pinion gear set designed for durability. Revolution Gear & Axle also includes a complete installation kit. This means you get all the bearings, races, seals, shims, and hardware required to properly set up your new gears. Proper installation is critical for the longevity and performance of your differential, and having all the necessary components in one box simplifies the process. The 4.88 ratio is a popular choice for trucks running 37-inch or larger tires, offering a significant improvement in acceleration and towing power.

When installing new gears, it's important to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving without heavy loads or high speeds, followed by an oil change. This allows the new gear teeth to properly mate and wear in, ensuring a long service life for your new differential setup. This package is designed for the Ford F-250's robust Dana 10.25" rear axle, ensuring a direct fit for the components.
