Duroflex 101
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.
Lock-N-Load For Long Arm Suspension
Designed to remove any stresses from bushings and welded brackets, the Lock-n-load lets your suspension move freely without bind when articulation is need.
Lock-N-Load
"Typical" Radius Arm systems inherently bind causing premature bushing wear and excessive stress on the brackets. The Lock-N-Load solves that problem.
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
Lock-N-Load
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...
- The best ride quality

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