The strongest front axle upgrade available for a GM Dana 60. The RCV Ultimate 300M CV Axle Set was engineered at the request of professional off-road racers who needed the smooth articulation of RCVs Ultimate CV designcombined with even more strength for extreme racing environments.

These axles are manufactured from 300M alloy steel, one of the highest strength aerospace grade materials used in off-road drivetrain components. The result is a CV axle set capable of surviving high horsepower, massive tires, aggressive steering angles, and brutal terrain without the binding, chatter, or breakage common with U-joints.

At any steering angle, from straight or full lock, 300M CV axles maintain consistent strength and deliver smooth, positive power transfer to the ground. Perfect for rock bouncers, Ultra4 racers, mud trucks, heavy trail rigs, or any GM 1-ton drivetrain pushed beyond factory limits.

• Left & right 300M CV axle shafts
• 300M outer stub shafts
• SST seals & installation tool
• Installation hardware
• Synthetic moly grease
• Installation instructions
