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.

Lock-N-Load

"Typical" Radius Arm systems inherently bind causing premature bushing wear and excessive stress on bracketry. The Lock-N-Load solves that problem.

IT ALL STARTS WITH THE BUSHINGS

The Patented Duroflex™ Joint (metalcloakpatents.com) is the key to getting the greatest flex in a Ram bolt-on suspension kit. Period.

Duroflex Control Arm Joint Comparison

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.

The Duroflex Joint Provides The Best Ride. Period.

Duroflex Kevlar Bushing

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.

FULL SIZE Strength

3" Duroflex Joint for the RAM Truck; these joints are HUGE! Take all the benefits of maximum articulation, unlimited rotational range, the best NVH (noise/vibration/harshness) and combine that into a service free bushing infused with Kevlar. These joints are made specifically for FULL SIZE strength.

Lower Front Radius Long Arms

Engineered for ultimate clearance including both Up & Down travel under your Ram.

The beefy Long Arms also aid to the protect the vital components of the under carriage.

Allows maximum up and down wheel travel while keeping the pinion angle in check.

Has unparalleled on-road handling characteristics that some say are unprecedented in a suspension system.

Lower Front Radius Long Arms

Lock-N-Load

MetalCloak's Lock-N-Load Radius Arm system removes the most common problem that causes more long term damage to bushings and axles... BIND.

The Lock-N-Load extends at full droop, compressing one spring and extending the other.

At full stuff, the Lock-N-Load compresses. There is always compression and resistance.

Lock-N-Load Compression

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 eliminating stress on the bushings and brackets providing 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.

What are True Dual Rate Coils?

MetalCloak True Dual Rate™ Coils have one of the longest free length in the industry for greater articulation without sacrificing the OEM ride quality.


Without the advantage of the Dual Rate Design, the required Spring Rate would be too low and "squishy" -- just loading your Jeep up with supplies would affect ride height and quality. (Learn More About True Dual Rate Coils)

Understanding Dual Rate Coils


Front RAM True Dual-Rate anti-bow springs do not neck down like 'typical coils" and alleviates coil bow as the additional support from the larger diameter coil maintains structure and provides better performance.

SS-2038 SS-2039

Front Upper Spring Capture/Isolators

Polyurethane Front Upper Spring Capture/Isolators capture MetalCloak RAM True Dual Rate coils and isolate NVH (noise vibration and harshness) while keeping the coils centered.

Dodge Ram Front Upper Coil Pads

Front Lower Coil-Correct Captures

Front Coil Perch

Strong 3/16" .120 wall steel Front Lower Coil-Correct Captures work in conjunction with MetalCloak True Dual-Rate Ram Front coils to center, angle and capture the coil to eliminate coil bow.

Front Track Bar Bracket

Front Track bar bracket is made of thick 1/4" steel plate for a "no compromise" mount that also adds additional support mount at the cross member for increased strength and durability.

Front Track Bar Bracket

Rear Track Bar Bracket

Rear track bar drop bracket 1/4" THICK!!!! captures axle tub for extra strength with additional gussets for max strength: Rear Track bar brackets are made of thick 1/4" steel plate for a "no compromise" mount that also adds additional support mount at the axle tub for even more strength.

Rear Track Bar Bracket

Bump Stop Towers

3/16" hot rolled steel Plate spacer (3" x 3" .188 WALL Steel Tube) Front and Rear bump stops towers reposition the factory parts to function correctly for the added lift height.

Sway Bar Disconnects

When Lifting a Truck the sway bar links also need to increase in length to keep your sway bar adjusted properly. MetalCloak Extended Sway Bar Links bolt directly into the factory locations with no cutting or modification required.
