Yukon Gear & Axle YA GM11.5-30-40.25 Rear Axle Shaft 40.25in 30-Spline 1541H Alloy

The Yukon Gear & Axle YA GM11.5-30-40.25 is a high-strength rear axle shaft engineered specifically for 2011 and newer GM trucks equipped with the 11.5-inch rear differential. This axle delivers enhanced durability over factory components while maintaining an affordable price point, making it an ideal upgrade for trucks that see heavy hauling, towing, or off-road use.

Key Features:

• Constructed from 1541H alloy steel for superior strength compared to stock axles
• 30-spline configuration ensures proper engagement with differential side gears
• 40.25-inch length designed for precise fitment in GM 11.5-inch rear ends
• Cut-to-length design accommodates axle lengths from 35 inches to 40.25 inches
• Direct replacement for worn or damaged factory axle shafts

Yukon's 1541H alloy axle shafts provide the strength increase needed for modified trucks running larger tires, aftermarket differentials, or increased power output. The chromoly construction resists twisting and breaking under high-torque conditions, giving you confidence whether you're towing a heavy trailer or tackling challenging terrain. Compatible with GM 2500HD and 3500HD trucks from 2011 forward equipped with the AAM 11.5-inch (11.5" / 11.50") rear axle assembly.
