RCV Big Bell CV Axle Set for 40-Spline Dynatrac ProRock XD60, 72.5-Inch Width
The RCV Big Bell CV Axle Set is engineered for extreme-duty applications using the Dynatrac ProRock XD60 front axle with a 72.5-inch width and 40-spline configuration. Designed to handle massive torque loads, oversized tires, and the harshest off-road conditions, this axle set delivers smooth, reliable power through the full steering range without the bind or failure points of traditional U-joint axles.
Featuring RCV’s Big Bell constant velocity joints, this system provides increased articulation strength and durability for competition rigs, rock crawlers, and high-horsepower builds. Precision-machined and built from premium materials, the Big Bell CV design reduces stress on drivetrain components while improving steering control at full lock, making it the go-to solution for severe-duty ProRock XD60 setups.
