Yukon Gear & Axle YAW38840 Chromoly Front Inner Axle Left 32 Spline Dana 44

The Yukon Gear & Axle YAW38840 is a high-performance left-hand inner front axle shaft engineered specifically for Jeep JL Rubicon models equipped with the Dana 44 front differential. Built from premium 4340 chromoly steel, this axle delivers exceptional strength and durability for demanding off-road applications where stock axles may fail under extreme loads and articulation.

Key Features:

• Heavy-duty 4340 chromoly construction for superior strength and reliability
• Cold roll formed 32-spline design for maximum torque transfer
• Induction coil heat treating process ensures optimal hardness and wear resistance
• Wide Track design for proper JL Rubicon fitment
• Measures 21.3 inches in length
• Compatible with 7166 Series u-joints
• Direct replacement for left-hand side front inner axle shaft

Yukon's advanced manufacturing process combines precision engineering with premium materials to create an axle shaft that can withstand the rigors of rock crawling, mud bogging, and aggressive trail riding. The cold-rolled splines provide a tighter tolerance and stronger connection than cut splines, while the heat treating process creates a hard outer surface with a tough, ductile core that resists both wear and breakage.
