These CV Joint Retention Rings hold your Extreme Angle CV Joint in place without having to machine a circlip groove which leaves a STRESS raiser.
 
Circlip Grooves or Shoulders in the axle reduce the strength of the axle by 75% (See the Engineering Explanation in the images above)
 
Instead of a circlip groove or a shoulder or machining the spline to a stop point, we recommend a retention ring.
 
Available to suit both 28T and 30T splines
