Revolution Gear & Axle 07-21 Toyota Tundra 4.6L/4.7L 4.88 Ratio Gear Package

If you've lifted your 2007-2021 Toyota Tundra with the 4.6L or 4.7L engine and are running larger tires, you've probably noticed a big drop in acceleration and highway cruising ability. That's because the larger tires effectively make your engine's gears taller, forcing it to work harder to get you moving. This Revolution Gear & Axle 4.88 ratio gear package is designed to bring back that lost performance by changing the final drive ratio in your differentials.

This package includes all the necessary components to re-gear both the front and rear differentials on your Tundra. You'll get new ring and pinion gears, along with a complete master installation kit. This kit contains all the bearings, seals, gaskets, and hardware you'll need for a proper installation. The 4.88 ratio is a popular choice for Tundras running 35-inch to 37-inch tires, as it helps bring your engine's RPMs back into a more efficient and powerful range at cruising speeds. This means improved acceleration, better towing performance, and a more responsive feel from your truck.

Re-gearing your differentials is a significant job, and it's crucial to use high-quality parts and follow the manufacturer's installation procedures carefully, including the break-in period. This package from Revolution Gear & Axle uses well-built components designed to handle the demands of a lifted truck with larger tires. Ensure you have the proper tools and knowledge for differential work, or consult a professional mechanic to get this installed correctly. Proper installation and break-in are key to ensuring the longevity and performance of your new gears.
