JK Wrangler 4.5"/5.5" 4-Link Long Arm Compound Suspension

Product ID: *A1455
The Jeep JK Wrangler 4-Link Long Arm Compound Suspension Systemis the only 4-Link Long Arm system that combines technology with the Patent Pending DB3 Rear Geometry correction brackets that give the best control arm angle available at this lift height. (metalcloakpatents.com)

Highlighted system features are:
  • Front Weld on Upper control arm brackets
  • DB3 Rear Geometry Correction Brackets
  • High-Misalignment Vibration Dampening Duroflex™ Control Arms

The weld on front 4-Link Long Arm system provides exacting [click for more...] control over pinion angles at extremes and compliments the Rear DB3 drop brackets that are exclusive only to MetalCloak. The combined technologies of the True Dual Rate™ Coils, revolutionary DuPont™ Kevlar® fiber enhanced Duroflex™ Joints, and the 2 piece Durotrak™ bushing equipped Track Bars gives you a system that is unmatched in the off-road industry.

Every aspect of clearance has been taken into account with easy to install, bolt on correction brackets for rear control arms, shocks, track bars, and steering stabilizer. 4 Link front requires cutting factory brackets and welding upper front replacements.

This system also out performs most long-arm kits in travel, articulation, clearance and flex with the smoothest and most predictable ride on or off-road at a fraction of the overall modification at a great value.

Note: Front and Rear driveshafts required.

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

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

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 4-Link Long Arms

Duroflex Kevlar Bushing

The Lower Front Control Arms are precision engineered for our 4-link front suspension. Mounted using a bolt-on bracket, the control arms are designed for lift heights of 4.5 and up, provide amazing flex, the best pinion angle control for taller lifts, and still give incredible handling and the smoothest ride on or off road.

Upper Front 4-Link Long Arms

The Upper Front Control Arms are installed using a welded-on bracket for precise geometry.

Equipped with the Duroflex™ joints at the frame-end, the arms use the stock bushings or the MetaCloak Bushing Upgrade kit (not included) at the axle end.

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.

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!

The 6Pak™ Shock

The design of the 6Pak didn't just revolutionize shocks, it changed the suspension game forever.

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.
