Yukon Gear Dropout Assembly for Toyota 8in Rear Differential 30 Spline 4.88 Ratio

Yukon Gear & Axle is known for building solid drivetrain components, and this dropout assembly is a prime example for your 1979-1995 Toyota Pickup or 1984-1995 4Runner. If you're looking to change your differential gearing, perhaps for larger tires or more demanding off-road use, this unit is designed to make that swap straightforward. It comes as a complete, pre-assembled third member, meaning the critical setup of shims and backlash is already handled by expert Yukon technicians.

The case is made from nodular iron, which is stronger than standard cast iron. This improved rigidity helps keep the gears properly aligned under load, reducing deflection. Consistent gear contact is key for smooth operation and a long service life, especially when you're putting your drivetrain to the test. This assembly includes the yoke and is ready to be installed into your differential housing, then just bolt on the cover, add fluid, and you're set to go.

This dropout assembly features a 4.88 gear ratio, which is a popular choice for those running larger tires off-road, as it helps bring your engine RPMs back into an efficient range. It's also built with 30 splines for the differential side, matching the specifications for many Toyota 8-inch rear differentials from these years.
