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.

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.

A Comparison of Flex

Comparing the Flex of the Duroflex Joint with that of the Johnny Joint, the Teraflex Monster and the typical Clevite.

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 bracketry. The Lock-N-Load solves that problem.

Coil Springs 101

This short video covers all you need to know about the basics of how typical Coil Springs work compared to MetalCloak's True Dual Rate Coils.

Durotrak™ Bushing

Eliminate squeaks and clunks in your steering with the technology of MetalCloak’s Durotrak™ bushings; exclusively found in MetalCloak track bars.

"DB3" Rear Drop Bracket

Enjoy the confident handling and the smooth, comfortable ride you demand from your JK Wrangler with the DB3.

Outboard Shock Mount

Move the front lower shock mounts away from the Jeep frame rails and rotate the shock eyelet from factory position by 90 degrees allowing it to swing with the axle vs bind on the bushing.

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.

IT ALL STARTS WITH THE BUSHINGS

The Patented Duroflex™ Joint (metalcloakpatents.com) is the key to getting the greatest flex in a JK Wrangler 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 (34˚), Self-Centering, Rebuildable Joint with an OEM quality ride.

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.

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!

Duroflex Misaligned

Lower Front Radius Long Arms

Lower Front Radius Long Arms

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

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.

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 resistence.

Lock-N-Load Compression

What About Daily Driving?

Once "Locked" the Lock-N-Load coils are fully compressed creating a rigid arm for increased stability in daily driving.
Lock-N-Load Locked Position
Lock-N-Load Loaded Position
In the "Loaded" position, the Lock-N-Load is ready to provide up to 1.5" of compression or extension for additional off-road articulation and to relieve stresses from bushings and brackets.

What are True Dual Rate Coils?

MetalCloak JK Wrangler 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)

Not just any track bar bushing...meet the Patented Durotrak

Durotrak Bushing

The Patented Durotrak Bushing (metalcloakpatents.com) is a NVH (noise, vibration, harshness) bushing made with a proprietary elastomer compound unique to MetalCloak. The Durotrak two part bushing is comprised of two pieces that thread together making this bushing simple to install without a press, reduces vibration and harshness transferred to the driver, and improves vehicle steering input.

Rear Control Arm Correction Bracket "DB3"

DB3

MetalCloak's Patent Pending "DB3" Rear Control Arm Correction Kit is the only solution to lift a Jeep JK Wrangler over 3.5 inches without cutting off the factory brackets and other costly modifications. This product corrects the geometry of the control arms to enable the full use of up and down travel.

The entire bracket assembly is welded together for incredible strength, has built in approach skids, and all surfaces are angled to keep from catching on obsticles. Installs into factory locations that bolt it securely in place.

What Does It Do?

Adding this system improves rear control arm geometry and adjusts rear axle caster for lifted JK Wranglers. The flatter the control arms are the better; the benefits are immediately felt with a smoother ride and stable handling as the roll center has been adjusted. Braking performance also improves maximizing safety along with the comfort and performance of your Jeep JK Wrangler.


DB3 Correction Bracket

Typical Long Arm Vs DB3 Drop Bracket At Ride Height

The DB3 provides better control arm geometry than a any rear long arm available and is tucked close to the rear tire to give you an advantage in approach angle over rear long arm set ups.


Typical Long Arms at Ride Height

Typical Long Arm Vs DB3 Drop Bracket At Full Droop

When articulated, rear long arms can drag and catch on obstacles that can get you stuck; eliminate this problem with the DB3 and get even better control arm geometry.

Anti Flop Feature

Anti Flop Feature
This specially designed rod end has been engineered just for the JK Wrangler steering.

Full side to side range of motion ensures bind free steering when pushing the extremes of your Jeeps travel and articulation, while a limited "front to back" range of movement is built into the rod-end and eliminates the possibility of the offset to allow the rod end to "flop".

Track Bar and Stabilizer Relocation Bracket

Bracket raises the track bar to re-correct steering geometry when lifting over 3.5 inches; this is to be used in conjunction with the flipped Drag-link hi-steer set up ONLY when lifting a Jeep JK over 3.5 inches. The bracket also incorporates a raised mount for the steering stabilizer providing additional clearance!

IMPORTANT NOTES



Exhaust Loop: This suspension requires an Exhaust Loop Bypass Pipe on 2012+ JK Wranglers.

Shock Options: MetalCloak engineers have chosen shocks that have been proven to have the ideal synergy with our systems. We have not tested other shocks on the market as to whether or not they compliment our Game-Changer system or suppress its performance.

Driveshafts: Due to the long-travel MetalCloak suspensions provide, factory drive shafts will contact OEM components and wear quickly when at the extremes of articulation. Aftermarket front and rear driveshafts will be needed.

True Dual Rate Coils: MetalCloak does not recommend powder coating your True Dual Rate Coils. See instructions for additional details.

Suspension Alignment: We Recommend You Have a Suspension Specialist Align Your Jeep Once a MetalCloak Suspension is Installed.

System Customization: This item is being offered as a complete system that contains all the components shown. We cannot customize, replace or remove a component from the kit. If you need a custom order, all components are available individually and our sales team is happy to help you place your order.

System Components: If you purchase this system, and decide you do not need a component or part of the system, we cannot accept returns.
