The RCV Ultimate Dana 60 CV Axle Set transforms the front end of your 19781979 Ford F-250 or F-350 into a true heavy-duty performer. These high-strength constant velocity axles replace the factory U-joint shafts, delivering twice the strength of OEM while maintaining full torque transfer at any steering angle.

Unlike U-jointswhich weaken dramatically at full lockRCV CV joints stay just as strong at extreme angles as they are straight. This eliminates binding, improves steering feel, increases articulation, and drastically reduces axle shaft failures when running big horsepower, deep gearing, or oversized tires.

Whether youre restoring a classic, building a tow rig, or pushing a hardcore off-road truck, RCV Ultimate CV Axles provide unmatched durability with minimal maintenance.

Tech Insight

The 19781979 Ford Dana 60 is one of the most sought-after solid axles ever builtbut the original U-joint shafts are still a major limiting factor under modern power, tire size, and suspension capability.

RCV eliminates this bottleneck with: -A constant-velocity joint that maintains full strength at full lock -35 spline inner & outer construction for maximum torque load -Stronger steering performance and smoother articulation -Reduced breakage on heavy trucks, V8 swaps, and aggressive off-road setups

For big-tire classic Fords, this is the ultimate steering-side strength upgrade.
