THE TECH
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 (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!
Threaded Forged Ends
Forged for Strength...
