Yukon Jeep JK Non-Rubicon Dana 44 Rear Axle Shaft Kit - 1541H, 30-Spline
YA D44JKNON
The Yukon Jeep JK Non-Rubicon Dana 44 Rear Axle Shaft Kit is a heavy-duty replacement for Jeep Wrangler JK models equipped with the factory 30-spline Dana 44 rear axle. Built from heat-treated 1541H alloy steel, this 32" axle shaft is designed to handle the added loads created by larger tires, locking differentials, towing, and regular off-road use. It's a practical upgrade for daily-driven Jeeps, weekend trail rigs, and rock crawlers that need a stronger rear axle shaft without stepping up to a premium 4340 chromoly option.
This Yukon kit includes the rear axle shaft along with a new wheel bearing, axle seal, retainer, and ABS tone ring, giving you the major components needed for a proper axle shaft replacement. The 30-spline configuration is designed for compatible JK Non-Rubicon Dana 44 rear differentials, while the dual 5x5" and 5x5.5" wheel bolt patterns provide flexibility for factory and compatible custom wheel setups. Whether you're replacing a damaged shaft or upgrading before larger tires and harder trails, matching the spline count, shaft length, and wheel-end configuration is what matters most.
Includes:
- (1) Yukon 1541H Alloy Rear Axle Shaft - 30-Spline
- (1) Rear Axle Bearing
- (1) Rear Axle Seal
- (1) Axle Retainer
- (1) ABS Tone Ring
Important: Sold as one rear axle shaft kit, not a pair. Designed for compatible Jeep JK Non-Rubicon Dana 44 rear axles with 30-spline shafts. This is not the correct shaft for factory JK Rubicon 32-spline rear axle configurations. Verify the installed axle and wheel-end components before ordering.

FAQ
What is the advantage of a 1541H alloy rear axle shaft?
1541H alloy steel provides a good balance of strength, toughness, and value for heavy-duty axle applications. It's a practical upgrade for trail Jeeps running larger tires or seeing more off-road use without stepping up to a premium 4340 chromoly shaft.
Will this axle shaft fit my Jeep JK Non-Rubicon?
This kit is designed for compatible 2007–2017 Jeep Wrangler JK Non-Rubicon models equipped with a Dana 44 rear axle and 30-spline shafts. Verify the axle configuration before ordering, especially if your Jeep has been modified or fitted with an aftermarket axle.
Will this fit a Jeep JK Rubicon Dana 44 rear axle?
No. Factory JK Rubicon Dana 44 rear axles use 32-spline shafts, while this kit is designed for the 30-spline Non-Rubicon configuration. The axle shaft must match the installed differential and wheel-end assembly.
Does this kit include both rear axle shafts?
No. This listing includes one 1541H alloy rear axle shaft along with the bearing, seal, retainer, and ABS tone ring for one side. Two kits are required to replace both rear axle shafts.
Does the kit include the axle bearing and ABS tone ring?
Yes. The kit includes the axle bearing, seal, retainer, and ABS tone ring along with the 1541H alloy axle shaft. These components help simplify the replacement process by providing the major service parts together.
Can I use this axle shaft with an aftermarket locker?
Yes, provided the locker is designed for compatible 30-spline Jeep JK Dana 44 rear axle shafts. Verify the differential spline count and wheel-end configuration before installation.
Is this axle shaft suitable for larger tires and off-road use?
Yes. The 1541H alloy shaft is designed to provide increased strength and durability for trail riding, larger tire applications, and moderate off-road builds. For high-horsepower competition vehicles or extreme rock crawling, a 4340 chromoly shaft may be worth considering.
What should I inspect when replacing a rear axle shaft?
Inspect the axle bearing, seal surface, retainer, ABS tone ring, axle housing, and differential side gear splines. Proper installation of the bearing and retainer is important for axle retention and long-term reliability.
