Revolution Gear & Axle 07-23 Toyota Tundra 5.7L 10.5in Rear Axle 4.88 Ratio Ring & Pinion Set

If you've modified your 2007-2023 Toyota Tundra with larger tires, you've probably noticed a drop in acceleration and an increase in engine RPMs at highway speeds. Swapping to a lower gear ratio, like this 4.88 set from Revolution Gear & Axle, can bring back that lost performance. This change helps your engine operate in its power band more effectively, improving acceleration and making towing feel stronger again.

This ring and pinion set is built for the 10.5-inch rear axle found in Tundras with the 5.7L engine. Revolution Gear & Axle uses solid steel for these gears, ensuring they can handle the increased stress from larger tires and heavier loads. The 4.88 ratio is a popular choice for trucks running 35-inch to 37-inch tires, as it strikes a good balance between on-road drivability and off-road capability. Proper installation is key for these components; it's recommended to have them set up by a professional who can ensure correct backlash and gear pattern for quiet operation and long life.

When installing a new ring and pinion, it's crucial to follow the manufacturer's break-in procedure. This typically involves a period of moderate driving without hard acceleration or heavy loads, followed by oil changes to remove any initial wear material. This process helps the new gear teeth mesh properly and extends the life of the set.
