Description

The USA Standard Gear ZPKF9-A is a comprehensive pinion installation kit specifically engineered for the Ford 9-inch differential. Key features of this kit include the use of premium-quality Koyo bearings and races, renowned for their exceptional durability and smooth performance. The package contains all essential components for a successful installation: pinion bearings, races, a pinion seal, a pinion nut, a crush sleeve, along with marking compound and a brush for accurate application. The kit is backed by a 1-year warranty against manufacturer defects. This pinion installation kit is compatible with a wide range of Ford and Mercury vehicles equipped with the 9-inch differential. Specific fitments include the Ford Bronco (1966-1986), Ford F-100 (1957-1983), Ford F-150 (1975-1987), Ford Mustang (1965-1973), Mercury Cougar (1967-1979), and Lincoln Continental (1961-1979), among many others. Customers are advised to confirm fitment with their specific vehicle details before ordering. Fitment is confirmed for numerous Ford and Mercury models spanning from the 1950s to the late 1980s, including various E-Series vans, Fairlanes, Falcons, Galaxie, Mustangs, Rancheros, Thunderbirds, and more. If fitment issues arise, especially if recommended by the sales team, the seller will work with the customer to find a resolution, potentially waiving restocking or return shipping costs if the error was on their part and the item is in like-new condition.
