RCV Ultimate Carbon Fiber CV Prop Shaft for Polaris RS1The carbon fiber design with hard coated 7075 aluminum end yokes is nearly less weight than OEM, reducing rotational mass, increases acceleration, and reduces any possibility of vibration. Additionally, the dampening effect of carbon fiber will reduce shock load and stress on other components such as transmission and front differential. The heavier steel tube will see deflection at high RPM critical speed, the low mass and high rigidity of carbon
