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
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

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.
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.
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.
Made of a Proprietary Elastomer Compound, the High Vibration Dampening and Self-Centering characteristics of the Duroflex Joint means you will always get...

High Misalignment...
By adapting the High Transverse Flex characteristics of a typical Flex Joint, the Duroflex Joint gives you...
