What is a differential dropout assembly?

A differential dropout assembly, also known as a third member, is a pre-assembled unit containing the ring gear, pinion gear, differential case, and all internal components. It replaces the entire center section of your vehicle's differential housing, simplifying installation compared to rebuilding the original unit.

What is the benefit of the Yukon Dura Grip limited slip differential?

The Dura Grip limited slip differential uses clutches to bias torque to the wheel with more traction. This helps improve your vehicle's ability to move forward in slippery conditions or when one wheel loses grip, enhancing overall traction and performance.

Does this assembly come with everything needed for installation?

This is a complete dropout assembly that includes the differential, gears, yoke, and is pre-shimmed and set to the correct backlash. You will need to add differential fluid and a new differential cover gasket for installation. Always refer to the manufacturer's instructions for specific fluid type and capacity.

Product Details

If you're working on the rear differential for your 1985-2009 Toyota 4Runner, Lexus GX470, FJ Cruiser, or Pickup, this Yukon Gear dropout assembly is a complete, ready-to-install solution. This unit replaces your entire third member, simplifying the installation process significantly. It comes fully assembled, shimmed, and set to the correct backlash by expert Yukon technicians, meaning you can bolt it in, add fluid, and get back on the road with improved performance.

The heart of this assembly is the Yukon Dura Grip limited-slip differential. This clutch-type unit is designed to improve torque transfer and traction, especially when you encounter slippery conditions or uneven terrain. It works by biasing torque to the wheel with more grip, helping you maintain forward momentum. The case itself is made from nodular iron, a well-built material that offers increased rigidity and better power handling compared to standard cast iron. This rigidity helps maintain consistent gear contact under load, which is crucial for longevity and reliable performance.

This assembly includes a 3.73 gear ratio, which is a popular choice for balancing on-road drivability with off-road capability for many Toyota applications. It also comes with a 30-spline yoke, ready to connect to your driveshaft. Because this is a complete dropout assembly, it significantly cuts down on the specialized labor and tools typically required for a differential rebuild, making it a solid option for those looking to upgrade their drivetrain with confidence.
