BR-47 Blue 47gram Bump Rubber

This is for the BR-47 Black 47gram Bump Rubber.

Penske Racing Shock UK offer a wide range of progressive bump rubber, aiding in the spring stiffness at the end of damper travel. The progressive bump rubber gets stiffer, as it's compressed due to the conical ring design. This will provide the driver with a predictable feel and confidence inspiring handling. This bumper is designed for a 5/8" (16mm) shaft.

The below graph shows the bump rubber progressive curve for each colour:

Pro-tip: Bump rubber rings can be cut off, then mixed and matched to give you your own unique progressive curve.
