Yukon Gear & Axle YDAT100-411YDG Dropout Assembly Toyota T100 8.4" Rear Diff w/ Dura Grip LSD 4.11 Ratio 30 Spline

The Yukon Gear & Axle YDAT100-411YDG is a complete, fully assembled dropout assembly built specifically for the Toyota T100 8.4" rear differential. Each unit is assembled by expert Yukon technicians, arriving fully shimmed and backlashed to factory specifications — ready for a straightforward drop-in installation with no additional setup required.

This dropout assembly is upgraded with a Yukon Dura Grip clutch-type limited slip differential (LSD), delivering improved traction and reliability over a standard open differential. The Dura Grip design uses a clutch-pack system to bias torque toward the wheel with the most grip, reducing wheel spin and improving performance in low-traction conditions.

Key Features:

• 4.11 gear ratio for optimized torque and power delivery
• 30-spline axle shaft engagement for robust strength and durability
• Upgraded with Yukon Dura Grip clutch-type limited slip differential
• Fits Toyota T100 8.4" rear differential
• Includes yoke — everything needed for installation
• Fully assembled, shimmed, and backlashed to spec from the factory
• Built by expert Yukon Gear & Axle technicians

Yukon dropout assemblies eliminate the guesswork and labor of individual component shimming and setup, making them an ideal solution for gear ratio changes, LSD upgrades, or differential rebuilds. The included Dura Grip limited slip unit is a direct upgrade over the stock open differential, providing the traction advantages of an LSD without the complexity of a full axle rebuild.
