Product Details
Yukon Gear & Axle is well-known for making solid drivetrain components, and their ring and pinion sets are a popular choice for anyone looking to change their vehicle's gearing. This set is designed for Ford 8.8-inch differentials and features a 3.90 ratio. Changing your gear ratio can make a big difference, especially if you've upgraded to larger tires or added more power to your engine. A 3.90 ratio is often a good balance, helping to bring your engine RPMs back into a more efficient range on the highway while still providing good acceleration.
These gears are made from high-grade steel and are designed to run cooler and quieter than many other aftermarket options. Yukon engineers focus on the gear tooth surface finish to reduce friction and heat, and they ensure the structure and surface finish meet exacting specifications. This attention to detail means you're getting a well-built set that's made for reliability. This specific gear set fits a wide range of Ford vehicles, including popular models like the Ford F-150, Ford Explorer, and Ford Mustang from various years.
When installing a new ring and pinion set, it's important to follow the manufacturer's break-in procedure to ensure the gears mesh properly and last a long time. This set is designed to fit OEM specifications, making installation more straightforward.
