This Ford 9 Inch Ring and Pinion is a Revolution Gear replacement set for Ford 9″ differentials that use standard rotation gearing. Revolution Gear designs it to handle rugged off-road trails and highway cruising alike, so you get one gear set built for both without compromise.
This combination keeps noise and wear low over the life of the gear set, using the same material and heat-treating approach Revolution Gear uses across its wider Ford 9 Inch Ring and Pinion range.
This set suits Ford 9″ differentials running standard rotation gearing. The 3.89 ratio suits builds running larger tyres or carrying regular loads, recovering acceleration that a taller ratio would leave on the table. It sits just under the 4.10 option in aggressiveness. Ford 9″ housings are a popular swap for hot rods, muscle cars, and off-road trucks alike, check what your application needs before committing to this ratio.
Revolution Gear and Axle has built its reputation over more than a decade of street, off-road, and race use. Enthusiasts trust the brand for consistent quality across a wide range of applications, from classic hot rods to modern 4WD builds, a track record that gives you confidence this gear set will perform as well in your build as it has in thousands of others already on the road and trail.

Had the classic whine at 80. Diff turned up next morning, swapped it over myself with the fitting guide, return label was in the box. Three weeks on and dead quiet. Core charge came back inside a week.
Rural delivery so it was two days not one. The part itself is mint and the oil was in the box which I did not expect.
Price was the price, no surprises. Return pickup was already booked which made life easy.
