Duroflex Joint Revealed

The MetalCloak Duroflex Joint gives better dampening properties over OEM style rubber Clevite Joints and provides more misalignment than “other” inferior Flex Joints.

Vibration Dampening

We tested our Duroflex Joint using a "Shaker Table" and seismometer app to show how much Vibration Dampening the Duroflex Joint gives you compared to other industry leading joints.

A Comparison of Flex

Kevlar® is a synthetic fiber with extremely high tensile strength to weight ratio…five times stronger than steel and commonly used in bullet proof armor applications.

Duroflex Bushings w/Kevlar® can be identified by the MetalCloak “M” located on the outer surface.
