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.
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.
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.
IT ALL STARTS WITH THE BUSHINGS
The Patented Duroflex™ Joint (metalcloakpatents.com) is the key to getting the greatest flex in a JK Wrangler 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...
- The best ride quality
- No binding of your control arms.
- None of the micro-wear that DESTROYS Flex Joints
By adapting the High Transverse Flex characteristics of a typical Flex Joint, the Duroflex Joint gives you...
- Over 34° of Misalignment
- Over 68° per Control Arm
Because the Duroflex Bushing absorbs the millions of Rotational Micro-Movements found in your daily driving, you get...

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.
Forged for Strength...
The adjustable threaded sides are Forged that give a 37% higher fatigue strength over inferior cast parts, this EXTRA rock bashing strength will hold up to whatever you throw at em.
At MetalCloak We Take The Care To Build It Right...
Control Arm Duroflex Joint Alignment...
At MetalCloak we take the care to build every product right.
