Revolution Gear & Axle 11-16 Ford F-250 F10.5-D60RT Timken 4.88 Ratio Gear Package

Revolution Gear & Axle is well-known for providing solid drivetrain components, and this 4.88 ratio gear package for your 2011-2016 Ford F-250 is a prime example. If you've upgraded your tires to a larger size or are looking to improve your truck's towing performance, changing the ring and pinion gears is a common and effective way to bring your engine's RPMs back into an optimal range. This package is specifically designed for the Ford 10.5" (D60RT) rear differential, ensuring a proper fit for your heavy-duty truck.

This kit includes a full set of Timken bearings, which are a popular choice for their durability and smooth operation. Timken has a long-standing reputation in the industry for producing well-built bearings that can handle the stresses of daily driving and heavy loads. By using these quality bearings with the new 4.88 ratio gears, you're setting up your differential for reliable performance. The 4.88 ratio is a significant change from stock, meaning your engine will turn more revolutions for every rotation of your tires. This is ideal for larger tires, as it helps compensate for the increased rolling diameter and brings your cruising RPMs back down, improving fuel efficiency and reducing strain on the engine and transmission during towing or hauling.

When installing a new gear set, it's crucial to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving without heavy acceleration or towing, followed by an oil change. This process allows the new gear teeth to properly mate and wear in, ensuring long-term durability and quiet operation. This package contains the essential components for a ratio change, but always refer to the Revolution Gear & Axle installation instructions for specific details and recommended break-in procedures.
