Built for racers, engineered for extreme durability. The RCV Ultimate 300M Dana 60 CV Axle Set for the 9499 Dodge Super Duty Dana 60 Disconnect system is the highest strength CV axle upgrade available today. Designed at the request of professional off-road racers, these axles combine the unmatched smoothness of RCVs CV technology with the brutal strength of 300M alloy steel, delivering performance far beyond what any U-jointed shaft can offer.

300M CV axles maintain full strength at any steering angle, whether straight or full lock, by eliminating the binding, vibration, and steering shimmy that plague U-joints. RCVs patented Spherical Sealing Technology provides superior puncture and tear resistance compared to rubber CV boots, ensuring long lasting protection in the harshest terrain.

These axles also convert the factory three piece disconnect system into a stronger, more reliable two piece design. The OEM disconnect assembly becomes obsolete, greatly increasing durability while simplifying the front axle system.

Whether you're running high horsepower, launching off jumps, or crawling with massive tires, these 300M CV axles deliver maximum strength, smooth articulation, and race proven reliability.

• Left & right 300M CV axle shafts

Tech Insight

The OEM disconnect style Dana 60 front axle used in 9499 Dodge trucks is highly prone to failures due to its multi piece design and U-joint limitations.

Why 300M?

• 300M alloy steel is stronger and more fatigue resistant than chromoly
• Built for high horsepower and high impact race environments

Why CV instead of U-joints?

• CV joints have full torque strength at all angles
• No U-joint bind, no shutter, no steering wheel shimmy
• Far soother power delivery under load

Why Spherical Sealing Technology?

• More durable than rubber CV boots
• Better protection from rocks, debris, and heat
• Reduced maintenance in off-road environments

If you're pushing a D60 disconnect axle further than OEM ever intended, this is the upgrade that turns it into a race capable system.
