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.

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.

THE TECH

Forged Threaded Housing

The forged steel housing eliminates internal voids while ensuring uniform grain flow/structure for maximum strength; threads allow for adjustment when lengthen/shortening of the control arm.

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.

A graphical comparison of an OEM Clevite plus a typical Flex Joint equaling a MetalCloak Duroflex Joint.

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, 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.

High Vibration Dampening & Self Centering...

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

High Misalignment...

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

  • Incredible Misalignment
  • Self centering Control Arms

Absorbs Micro-Movements...

Because the Duroflex Bushing absorbs the millions of Rotational Micro-Movements found in your daily driving, you get...

  • Improved Ride Quality
  • None of the micro-wear that DESTROYS Flex Joints

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.

Done.
