Built with 300M inner axle shafts and RCV’s oversized Dana 60–architecture CV joints, this 1-piece FAD-eliminator design delivers unmatched strength, steering smoothness, and durability under extreme load.\u003c\/p\u003e\n\u003cp\u003eThese axles eliminate U-joint binding and the oscillation\/crow-hop common with OEM shafts. With six fully engaged contact points at every steering angle up to 45°, you get 100% power transfer even at full lock.\u003c\/p\u003e\n\u003cp\u003eThe 1-piece design eliminates the Jeep’s factory Front Axle Disconnect coupler, but retains full electronic module functionality—meaning no warning lights and no tuning or modification required.\u003c\/p\u003e\n\u003cp\u003eBuilt to withstand serious abuse and backed by RCV’s Lifetime No Questions Asked Warranty up to a 43
