Yukon Gear & Axle YDAF9-411YGL-35 Dropout Assembly for Ford 9in Differential with Grizzly Locker 4.11 Ratio 35 Spline

The Yukon Gear & Axle YDAF9-411YGL-35 is a complete, fully assembled dropout assembly designed for the iconic Ford 9-inch differential. Built by Yukon's expert technicians, this unit arrives fully shimmed and backlashed to factory specifications, making installation straightforward and eliminating the guesswork of a custom build.

This dropout assembly is upgraded with a Yukon Grizzly Locker, a full-spool-style locking differential designed to deliver maximum traction and reliability under demanding conditions. The Grizzly Locker engages both axle shafts simultaneously for consistent, locked differential performance — making it an ideal choice for off-road, rock crawling, and high-stress applications.

Key Features:

• 35-spline axle shaft compatibility for high-torque applications
• 4.11 gear ratio for improved torque multiplication and off-road performance
• Fits Ford 9-inch differential housings
• Comes fully assembled, shimmed, and backlashed to spec — ready to drop in
• Upgraded with the Yukon Grizzly Locker for maximum traction and locking reliability
• Built by Yukon factory technicians for consistent quality and precision
• Yoke not included — order separately as needed

The Ford 9-inch differential is one of the most popular and versatile axle platforms in performance and off-road builds. Yukon's pre-assembled dropout saves significant labor time compared to sourcing and setting up individual components, while ensuring ring-and-pinion mesh and bearing preload are correctly set from the start.
