Yukon Gear 1.250in Pinion Adaptor Sleeve (Stock Pinion into Large Support)

This 1.250-inch pinion adaptor sleeve is designed to fit a stock 28-spline pinion into a 35-spline pinion support, commonly found in Ford 9-inch rearends. It's a well-built piece from Yukon Gear & Axle, a name you can trust for drivetrain components. This sleeve is crucial when you're upgrading or rebuilding a Ford 9-inch differential and need to ensure proper fitment between your pinion and the larger support housing.

The sleeve's precise dimensions allow it to slide over the stock pinion, effectively changing its spline count to match the larger support. This avoids the need for more complex machining or finding a different pinion altogether. It's a straightforward solution for a common drivetrain modification, ensuring your gears mesh correctly and your differential operates smoothly. Yukon Gear & Axle is known for its comprehensive line of small parts that help complete any differential job, and this adaptor sleeve is no exception.

This adaptor sleeve fits a wide range of Ford vehicles, including classic Broncos, F-100s, and Mustangs, making it a versatile part for many Ford 9-inch rear axle applications. Make sure to confirm fitment for your specific vehicle and axle setup.
