Yukon Gear & Axle YA Chromoly Inner Dana Spline Axle Shaft

Yukon Gear & Axle YA Chromoly inner axle shafts are heavy-duty replacement and upgrade axle shafts for Dana differentials. They suit off-road, trail and high-torque use where factory shafts can twist or fail. Each shaft is built around a Dana-style spline count to match the differential it replaces. Use it as an inner axle, also called an inner axle shaft, as a direct replacement for a worn or broken stock shaft, or as a stronger upgrade.

Key Features:

• 4340 chromoly construction: High-tensile strength steel gives much more strength than many factory shafts.
• Cold roll formed splines: This production method helps the splines stay strong and engage accurately.
• Advanced induction coil heat treating: The heat treatment adds durability and fatigue resistance under load.
• Precision machining: Machined for correct spline engagement and fit in the matching Dana differential.
• Application-specific designs: The line includes inner shafts for different Dana differentials, spline counts and axle sides. Choose the version that matches your differential and axle.

Yukon Gear & Axle is a well-known name in drivetrain and differential components. The YA Chromoly line is designed for owners who want better reliability from the axle without giving up a factory-style fit. It suits rebuilds, tire upgrades and trail builds.
