RCV Ultimate Dana 44 300M Axle Shaft Kit for Jeep Wrangler JL & JT Rubicon

RCV Performance Ultimate 300M CV Axles for Jeep JL Wrangler & JT Gladiator Rubicon with Dana 44

RCV Performance Ultimate 300M CV axles for the Jeep JL Wrangler and JT Gladiator Rubicon with Dana 44 axles deliver exceptional strength and ultra-smooth operation you can feel on and off the road. These axles replace the factory JL shafts with high-durability constant velocity (CV) joints, eliminating the vibrations and wheel “chatter” typically caused by uneven power transfer from U-joints.

RCV CV joints feature six points of engagement throughout the full range of motion—up to 45 degrees of articulation—providing maximum strength even at full steering lock.

The latest CV design for the JL Dana 44 is 18% larger than the previous-generation Dana 44 model and is built using architecture derived from the Dana 60. Testing confirms that these axles are over twice as strong as OEM shafts, offering unmatched reliability even with oversized tires and high-output powertrains. RCV axles are low-maintenance and ensure smooth, quiet operation on the trail and on the road. Covered by a lifetime warranty for tires up to 43 inches.
