Yukon Gear & Axle YP FSF10.25-35 Full Spool for Ford 10.25/10.5 Differential 35 Spline

The Yukon Gear & Axle YP FSF10.25-35 is a high-performance full spool designed specifically for Ford 10.25 and 10.5 rear differentials with 35-spline axles. A full spool replaces the spider gears in your differential, permanently locking both axles together to ensure 100% power transfer to both wheels at all times—making it ideal for drag racing, rock crawling, and extreme off-road applications where maximum traction is essential.

Key Features:

• Manufactured from high-strength forged steel for exceptional durability in demanding performance environments
• 35-spline design engineered to work with factory or aftermarket axle shafts
• Eliminates differential slippage by mechanically locking both axles together
• Provides consistent power delivery to both wheels, maximizing acceleration and traction
• Features aggressive 45-degree pressure angle for optimal strength and load distribution
• Precision-machined to OEM tolerances for proper fitment and reliable operation
• Direct replacement for factory carrier—no modifications required for installation
• Ideal for competition use, dedicated off-road vehicles, and high-horsepower applications

Yukon performance spools are engineered for racers and off-road enthusiasts who demand maximum traction and bulletproof reliability. By eliminating the complexity of limited-slip differentials, a full spool provides maintenance-free performance and ensures both tires receive equal power under all conditions. Note that spools are designed for racing and off-road use—they are not recommended for street-driven vehicles due to increased tire wear and handling characteristics during turns.
