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.
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.
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.
THE TECH
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.
Control Arm Duroflex Joint Alignment...
At MetalCloak we take the care to build every product right.
Most manufacturers build their control arms misaligned from center. Why? It simply costs less to do so.
By not cutting any corners, our joints are Centered and Aligned reducing wear and improving performance.
It makes them easier to install, too!
Lower Front 4-Link Long Arms
The Lower Front Control Arms are precision engineered for our 4-link front suspension. Mounted using a bolt-on bracket, the control arms are designed for lift heights of 4.5 and up, provide amazing flex, the best pinion angle control for taller lifts, and still give incredible handling and the smoothest ride on or off road.
Upper Front 4-Link Long Arms
The Upper Front Control Arms are installed using a welded-on bracket for precise geometry.
Equipped with the Duroflex™ joints at the frame-end, the arms use the stock bushings or the MetaCloak Bushing Upgrade kit (not included) at the axle end.
Threaded Forged Ends
Forged for Strength...
The adjustable threaded ends are Forged providing a 37% higher fatigue strength over inferior cast parts, this EXTRA rock bashing strength will hold up to whatever you throw at em.
