Yukon Chrysler 8.75in Diff 489 Case Dropout Assembly - 3.55 Ratio 30spl w/ Sure-Grip (w/o Yoke)

Starting with a nodular iron case, this Yukon dropout assembly is built for improved rigidity and power handling. This means consistent gear contact and a longer service life for your differential. It’s designed for the Chrysler 8.75-inch, 489 case rear end, a popular choice for many classic Mopar vehicles.

This isn't just a standard differential; it comes upgraded with a Sure-Grip/Powr-Lok clutch-type limited-slip differential. This four-spider-gear design helps distribute torque more evenly between the wheels, giving you better traction when you need it most, whether you're accelerating hard or navigating less-than-ideal road conditions. The assembly is fully shimmed and backlashed to factory specifications by expert Yukon technicians, so it’s ready to be installed right into your housing. Just bolt on the cover, add fluid, and you're good to go.

This dropout assembly features a 3.55 gear ratio, which offers a good balance between off-the-line acceleration and highway cruising. It's built with 30 splines for the axle shafts. Keep in mind that this unit does not include the driveshaft yoke, so you'll need to reuse your existing one or source a compatible replacement. It fits a wide range of classic Chrysler, Dodge, and Plymouth vehicles from the 1960s and early 1970s, including models like the Dodge Charger, Plymouth Barracuda, and Chrysler New Yorker.
