Genuine Metalastik heavy duty 'Rotoflex' rubber drive couplings, or 'donuts' as they are ofter known as. Used in older vehicles within the driveline, designed to cushion the driveline take up, reducing shock loadings on gearboxes, axles, universal joints and drive shafts.
Standard OEM replacement versions usually fail as soon as they are subjected to much higher than standard power outputs and the rigours of motorsport use. These genuine heavy duty replacements can cope with much higher torque loadings, ensuring a much longer, more reliable service life.
Metalastik donut couplings allow significant angular deflection (up to 5° constant or 10° momentary) without requiring any lubrication.
Please see the size chart for fitments. During fitting, ensure the steel retention band is not cut and removed until all bolts are fitted and torqued up. 3 sizes, listed via the Pitch Circle Diameter (PCD) of the three yoke mounting holes.
