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.

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
Duroflex Bushings
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, 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...
- The best ride quality
- No binding of your control arms.
- None of the micro-wear that DESTROYS Flex Joints
High Misalignment...
By adapting the High Transverse Flex characteristics of a typical Flex Joint, the Duroflex Joint gives you...
- Incredible Misalignment
- Self centering Control Arms
Absorbs Micro-Movements...
Because the Duroflex Bushing absorbs the millions of Rotational Micro-Movements found in your daily driving, you get...
- Improved Ride Quality
- None of the micro-wear that DESTROYS Flex Joints
True Bearing Surface...
The outer surface of the Duroflex Bushing acts as a bearing, breaking free when called for, giving you...
- Maximum Rotation & Articulation
- No "Binding Up" of the Control Arms
Low Maintenance & Rebuildable...
Unlike typical Flex Joints, the Duroflex does not require replacing key parts every year like others...
But, when you do need to rebuild it, it is MetalCloak Easy!
Just pull out the Duroflex Bushing, clean it up, add some new Teflon impregnated, synthetic silicone grease. Reassemble.
Done.
