Ford Racing Bronco M210 FDU 5.38 Ratio Upgrade Kit

Ford Racing, known for its performance parts and racing heritage, offers this M210 FDU 5.38 Ratio Upgrade Kit specifically for the 2021-2024 Ford Bronco. If you're looking to enhance your Bronco's off-road capability, especially when running larger tires, changing the differential gear ratio is a key modification. This kit allows you to re-gear your front differential to a 5.38 ratio, which helps bring your engine's RPM back into its optimal power band after a tire size increase.

This kit includes the necessary ring and pinion gears to change the final drive ratio in your Bronco's M210 front differential. A lower numerical ratio, like 5.38, means the engine will turn more times for each rotation of the wheels. This is crucial for maintaining acceleration and drivability when you've upgraded to larger, heavier off-road tires that would otherwise bog down the vehicle. Proper gearing ensures your engine isn't constantly struggling, improving performance and reducing strain on the drivetrain.

Installing a gear set like this is a significant drivetrain modification that requires specialized tools and knowledge for proper setup. It's recommended to have this kit installed by a professional mechanic experienced with differential gear installation. This upgrade is particularly popular for Broncos used in serious off-roading, rock crawling, or any application where maximum traction and control are needed at lower speeds. Ensure you also consider re-gearing the rear differential to match for optimal performance and to avoid damaging your 4WD system.
