Jeep JK Drivetrain Axle - Front Right Inner - Yukon Gear & Axle - 4340 Chromoly - `07-`12

Jeep JK Drivetrain Axle - Front Right Inner - Yukon Gear & Axle - 4340 Chromoly - `07-`12 is a direct-fit replacement inner axle for Dana 30 fronts on 2007–2012 Jeep JKs. This right-hand inner shaft is built to handle larger tires and increased driveline loads with upgraded materials and processes.

Measured at 34.5" and featuring 27 splines, this Yukon 4340 chromoly inner axle uses 760X series U-joints and is intended as a heavy-duty replacement for the Dana 30 front axle. Yukon manufactures these shafts using cold roll formed splines and advanced heat treating to improve tensile strength and wear resistance. Compared to many OE shafts, Yukon states up to 50% increased strength for extreme performance applications. The axle includes Yukon’s limited lifetime warranty for manufacturing defects and breakage, with a first "No Questions Asked" replacement option; Yukon (through Randy's Ring & Pinion) makes the final warranty determination.
