Our top of the line Four Link Game Changing Suspension System is a bolt on system that requires ZERO welding and [click for more...] features patented technology available nowhere else.

The MetalCloak Game Changing Duroflex™ Joints are the only vulcanized elastomer, self-centering joint enhanced with DuPont™ Kevlar® fiber – providing incredible durability with more misalignment in the control arms and better vibration dampening than anything else available. Exclusive to MetalCloak (see detailed info in the main body).

The Front Four Link Game Changer is comprised of thick 2.0 DOM .25 (1/4) wall steel front lower control arms with strength that can take abuse with forged threaded ends for the ultimate in durability. The upper front control arms are 1.25 DOM .1875 (3/16) wall steel and formed to provide clearance for up and down travel. Upper and Lower Control arms utilize our patented Duroflex bushings for bind free, service free articulation.

The Front Long Arm Frame Mounts are used in replacement of the factory mounts to install the front control arms for the long arm suspension. Mounts are fully welded and boxed for maximum strength; the 1/4" steel brackets are low profile for clearance and are finished in gold zinc for a long lasting finish and feature a bolt-on installation without any welding. *Front factory brackets must be removed for install.

The Rear Long Arm does require cutting off the rear factory control arm brackets but provides the most consistent wheelbase over the full range of travel for optimal performance. Lower Control arms are made of strong 2.0 DOM .25 (1/4) wall steel with strength that can take abuse and are enhanced even further with forged threaded ends for the ultimate in durability. The upper rear control arms are 1.5 DOM .1875 (3/16) wall steel and formed to provide clearance for both up and down travel. The Rear "BOLT-ON" Control arm brackets are formed of 1/4 Steel Plate and angled to slide over obstacles with out catching. This system does require cutting off the rear factory control arm brackets and is for the off-roader that demands precision when it comes to wheelbase and pinon angles.

This system comes with a complete 3/16" steel replacement crossmember! The Crossmember is CAD designed, made of thicker steel over factory and provides additional attachment points that adds structure/strength to your Jeep.

MetalCloak True Dual Rate™ Coils provides the most comfortable and stable ride over traditional single rate lift springs, and provide better load handling than the typical "progressive/multi-rate" coils. Our True Dual Rate coils are extra long in free-length to maintain contact for extreme articulation. MetalCloak has over a decade of proven dual-rate coil performance.

The front true dual rate coils come with MetalCloak's Front Lower Coil Correction Pads. This polymer isolator replaces the OEM plastic part and corrects the coil bow that may be caused when using the worn parts. Fits in factory location and is a quick upgrade to fine tune your Jeep.

MetalCloak Thermoset Elastomer Upper Front Coil Isolator upgrade pads are designed to last and outperform factory parts. The pads are made specifically for MetalCloak True Dual Rate Coils and are model specific.

The Durotrak bushings reduce NVH (noise, vibration and harshness) that can be transferred to the driver and provides a smoother ride while also improving the vehicles steering input. The patented bushing is a 2-part design that can rotate 360 degrees in a vertical plane unhindered while minimizing horizontal forces to keep the Jeeps axle centered and you going in the right direction.

We offer a choice in shocks; run the shock set-up you choose to fit your build needs. If you have a different idea of what shocks will work best for you- go for it. The choice is yours to buy the suspension best for your build, the choice up to you.

Adjustable height front and rear bump stops are a MetalCloak first and allow you to adjust the travel to be tailored to the size of tire you have optioned for. Add more bump stop or remove to adjust to the clearance you need without having to remove the coils.

All MetalCloak suspension components, are designed for maximum up AND down travel while providing the best suspension geometry available to deliver the performance you demand.

MetalCloak “components” have been proven safe with the FMVSS certificate of safety configured with 37inch tires, full body armor and suspension lift.

Note: Due to the long-travel MetalCloak suspensions provide, factory drive shafts will contact OEM components and wear quickly when at the extremes of articulation. An aftermarket driveshaft will be needed.

Note: 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 they complement our Game-Changer system or suppress its performance.

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

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

Note: 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.

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

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 (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!

What are True Dual Rate Coils?

MetalCloak JT Gladiator 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 Front / Rear)
