Metalastik Rotoflex Rubber Drive Donuts
Genuine Metalastik Rotoflex rubber drive donuts or couplings, used in driveline applications of some early vehicles, typically to take the whip out of driveshaft or halfshaft assembilies and cushion the drive take up, reducing shock loadings on gearboxes, axles, universal joints and shafts.
The standard OEM replacement versions usually failed prematurely when subjected to the abuse received during motorsport use, in highly modified cars with much higher than standard power outputs. These genuine heavy duty replacement versions will ensure a much longer service life and have been used in motorsport for decades, offering the best solution without resorting to re-engineering or replacing the original driveline system.
Please see the chart for fitments, when fitting, do not remove the steel band until fully installed. 3 sizes, listed via the Pitch Circle Diameter (PCD) of the three mounting holes of their yokes.
