RCV Ultimate IFS CV Axles for Independent Front Suspension are designed to overcome the limitations of your Ford F-150 or F-150 Raptor IFS axle shafts. Ultimate IFS CV Axles provide increased strength that original equipment axle shafts just can't match. Even if you have big tires and big power there are no worries. While our patented Spherical Sealing Technology provides much greater resistance to punctures and tears than rubber CV boots. Ultimate IFS CV Axles are low maintenance, and are backed with a "No Questions Asked" limited lifetime warranty. Our IFS CV axles meet and exceed the strength of a straight axle swap, while allowing you to maintain the traction, smoothness and control of your IFS. Ultimate IFS CV Axles are race proven, and used by racers in XRRA, Off Road Racing, and the TORC series. Put the power down with confidence!Axle set includes driver and passenger side axles, each fitted with a Super Duty Chromoly Dome-Mass Cage and Race with SST, and a Pro4 Super Inboard CV Joint. Axle set comes prelubed, and includes a tube of RCV synthetic moly grease for future lubrication needs. Black oxide coating is standard. Optional nickel plating is available for extra corrosion resistance in salty environments.
