Inner CV Adaptor Flange

The Inner CV Adaptor Flange is a hardened steel component that connects the differential output shaft to the inner CV joint. This flange bolts to the inner CV joint and splines onto the differential output shaft, transmitting engine torque from the differential to the half shaft.

The flange must handle full engine torque while rotating at wheel speed. It provides the critical connection between the differential and the CV axle, allowing the suspension to articulate while continuously transferring power. The splined connection to the output shaft allows for slight axial movement as the suspension compresses and extends.

This is an OEM replacement part that comes standard with the Rush SR. Sold individually (one per half shaft).
