The balls driveshaft «RCV» keep velocities in each angular position of driveshaft.

It's an advantageous alternative to "double joint". The very high level of accuracy and durability offers no play and no wear run after run.

The « RCV » balls driveshaft are made with high accuracy from special steel hardened. Combined with high quality ceramic balls (Si3N4 - grade 5 - hardness > 1400 HV) you can keep them for a long time car after car, costly parts stay like new for several years if you respect the preconisation of use (see user's manual). Occasionally you need to change the inner "POM" cage a cheap operation.

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

RCV balls driveshaft suppresses the disadvantages of double joint :

Constant velocity

Sizes

Inner plays

Inertia

Narrow ball bearing

Servicing

 

With RCV balls driveshaft :

Tire works better

Improve lateral grip

Improve traction

Steering radius shorter & more constant

Increase front reactivity

Increase rear stability

The stability gain of the rear is very appreciable with the new Mid motor chassis

 

RCV balls driveshaft is the perfect association with active rear system (ARS) :

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

Less toe-in in compression = Less braking in curve

Get a car easier to drive !!
