Yukon Ring & Pinion Gear Set For Dana M300 For Ford F350 DRW & F450 4.88 Ratio 37-Spl Standard Open

The 37-spline count on this Yukon ring and pinion gear set is specifically chosen for the Dana M300 differential found in 2017 and newer Ford F-350 DRW trucks. This 4.88 ratio is a popular choice when upgrading to larger tires or adding significant horsepower, as it helps bring your engine's RPMs back into an optimal range for towing and general driving. Yukon uses advanced heat-treating techniques to ensure the structure and surface finish meet exacting standards, making these gears a solid option for heavy-duty applications.

When you're rebuilding your differential or re-gearing for larger tires, a well-made ring and pinion set is crucial. Yukon's engineers focus on precise design and rigorous quality testing to create gears that perform reliably. This set is designed for the Dana M300 axle, and it's important to note that while it fits the F-350 DRW, the F-450 and F-550 models use a different spline count (41-spline) and may require a different differential case. This particular set is for standard open differentials.

Yukon Gear & Axle backs these ring and pinion sets with their Y.E.S. Plan, a lifetime protection plan that covers your gear set for as long as you own your vehicle. This offers peace of mind, especially when you've invested in significant drivetrain upgrades. Installation of a ring and pinion set is a complex job that requires specialized tools and knowledge; it's highly recommended to have this done by a professional mechanic to ensure proper backlash and gear pattern for longevity.
