The patent system « R-CVD balls joint» warranties the perfect stability of the velocity, independently of the angle between input and output driveshaft. « R-CVD » is a true CV driveshaft (see note Constant_velocityV2.pdf).

Patent n° FR 12 59048

With a similar size to your current driveshafts, the « R-CVD » deletes inconvenient vibrations of the wheel, increases stability, traction and behaviour in cornering.

The « R-CVD » are developed in different types to give you an optimal answer in function of your using requirement.

The « R-CVD » are made with high accuracy from special steel hardened. Combined with high quality ceramic balls (Si3N4 - grade 5 - hardness > 1400 HV) you obtain the perfect CV driveshaft performance.

If you are not satisfied by performance of your product, you have 14 days to send back us with complete refund (in accordance with Terms and conditions)

A sercice of maintenance (remplacement of defective components) is offered free of charge (except shipping costs) during 2 years after the date of purchase.


To get a perfect wheel rotation we introduce an innovative wheel hex system without pin and screw.


R-CVD vs Double Joint & CVD ?

Balls driveshaft R-CVD suppresses the disadvantages of double joint :


Inner plays


Narrow ball bearing


Balls driveshaft R-CVD it’s :

No vibration wheels

More lateral grip

More traction

Steering radius shorter

Balls driveshaft R-CVD is the perfect association with active rear system (ARS) :

Less toe in = More speed limit (with “stock” motor)

Less toe out in compression = More corner speed
