RCV Performance Ultimate 300M CV Axles simply replace your Dodge Dana 60 U-joint axle shafts with a high-strength constant velocity design.. These CV axles were designed at the request of champion off road racers. They wanted the smoothness of RCV Ultimate CV axles with additional strength to handle major league abuse. We came to their rescue with Ultimate CV Axles made from 300M alloy steel. These axles are just as tough at a straight angle as they are at extreme angles - where U-joints are weakest. Ultimate 300M CV Axles also eliminate U-joint binding to allow smooth transfer power to the ground. Even if you have big tires and big power there are no worries. Ultimate CV Axles are low maintenance and operate with a smoothness you can feel - whether off road or on the street. And we back it all with a "No Questions Asked" limited lifetime warranty.Axle set includes right and left CV axle shafts, outer stubs, SST seals and installation tool, installation instructions, synthetic moly grease, and installation hardware. Black oxide coating is standard. Optional nickel plating is available for extra corrosion resistance in salty environments - contact us for details, or use our Custom Axle Configuration Form.Fitment Notes:'89-'93 W250: Only fits the models with Cummins Diesel Engines'75-'93 W350: Does not fit '75 W350 with Dana 70 closed knuckle applications or mid 80's W350 with Dana 44 axlesPart:Axle Model:Type:OEM Inner Spline:OEM Outer SplineRCV Inner Spline:RCV Outer Spline:OEM Left Inner Axle Length:OEM Right Inner Axle Length:OEM Outer Stub Length:Warranty Voided:Boot Technology:300M Dodge Ram W250 ('89-'93) Cummins -Ram W350 ('75-'93) Dana 60.
