Manufactured from high-tensile 4340 chromoly steel, this axle shaft delivers substantially greater strength and fatigue resistance compared to factory replacement shafts. Whether your JK is a daily-driven trail rig, overland build, or dedicated crawler, this kit is designed to improve durability and confidence on demanding terrain.\u003c\/p\u003e\n\u003cp data-end=\"1102\" data-start=\"646\"\u003eYukon uses advanced manufacturing processes including cold roll formed splines and induction heat treating to maximize spline strength and long-term reliability. This complete kit includes the axle shaft along with the bearing, seal, ABS ring, retainer, and wheel studs for a more complete installation package. Designed for either left or right side use, this shaft maintains proper factory-style fitment while significantly increasing rear axle strength.\u003c\/p\u003e\n\u003cp data-end=\"1115\"
