Duroflex Joint Revealed

The MetalCloak Duroflex Joint takes the best qualities of OEM style Clevite Joint and the popular Johnny Joint style Flex Joint and combines them.

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

Comparing the Flex of the Duroflex Joint with that of the Johnny Joint, the Teraflex Monster and the typical Clevite.

What is Corner Travel Index?

Since 2014 MetalCloak has tested thousands and thousands of rigs at events all across the county collecting specs on the build and cataloging the results. The data collected allows us to make our own products better.

FMVSS 126 Compliant

MetalCloak not only has the best off road flex, but we are also Federal Motor Vehicle Safety Standard 126 certified and compliant. No other company can match our on- and off-road performance.

THE TECH

IT ALL STARTS WITH THE BUSHINGS

The Patented Duroflex™ Joint ( metalcloakpatents.com) is the key to getting the greatest flex in a bolt-on suspension kit. Period.

Duroflex Control Arm Joint Comparison

MetalCloak has taken the best features of the most widely used control arm joints and combined those features to create the Duroflex Joint, producing a Low-Maintenance, High-Misalignment (34˚), Self-Centering, Rebuildable Joint with an OEM quality ride.

Duroflex Kevlar Bushing

Now with Kevlar!

DuPont™ Kevlar® Fiber is now compounded in the proprietary elastomer of the Duroflex Bushing, bringing even more strength, durability and performance.

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.

The Duroflex Joint Provides The Best Ride. Period.
