Who Is MetalCloak?
MetalCloak creates Game-Changing Products for the Off Road Enthusiast.
"Typical" Radius Arm systems inherently bind causing premature bushing wear and excessive stress on bracketry. The Lock-N-Load solves that problem.
This short video covers what you need to know about the basics of the Duroflex Joint. How it should be used and what to expect when using it.

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.
What Are The Applications For The Lock-N-Load?
The Lock-N-Load is designed to ONLY work the front of a linked radius arm suspension.
The Lock-N-Load ONLY replaces the Passenger side upper control arm (your current driver side upper control arm remains in place).
The upper control arm must have a joint that connects at the lower control arm and a clevis that connects at the axle end.
The Lock-N-Load will currently work on most any radius arm suspension that the passenger side upper arm measures between 16" and 17" from eye to eye.
Note: If your radius arm set-up meets these parameters it will work whether you have a JK or a JK or some other custom build (though it has only been designed and tested with the JK in mind).
How Does The Lock-N-Load Work?
The Lock-N-Load performs as a standard "solid control arm" when locked; when unlocked "or loaded" it allows for the axle to roll forward or backward without reliving stress on the bushings and brackets that will provide a longer service life AND directly equate to better articulation that keeps tires on the ground.
The lock-n-load is designed to lock or unlock the spring without changing the length of the control arm; the unique and patented design provides stability on the road when locked out and increased suspension mobility when off road.
IT ALL STARTS WITH THE BUSHINGS
The Patented Duroflex™ Joint ( metalcloakpatents.com) is the key to getting the greatest flex in a JL 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...

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