The Four Link Long Arm Suspension System is a bolt-on system that requires ZERO welding and provides exacting control over pinion angles at extremes and is engineered to complement the geometry of our rear bolt-on long arms. The front of the Jeep is set up with Duroflex Front 4-Link Long Arms, and you get the choice in the rear of either the Patented DB3 Mid Arm or a full Rear Long Arm setup.

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 damping than anything else available. Exclusive to MetalCloak (see detailed info in the main body).

The Front 4-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" .1875" (3/16") wall 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, 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 installation.

Choose the rear system you desire. Select the patented bolt-on Rear DB3 Mid Control Arm system or a Rear Long Arm System.

The Rear DB3 control arm kit is a true bolt-on system with zero cutting required. Feel the improvement in acceleration, braking, climbing, and steering with the DB3. Our simple-to-install, bolt-on bracket repositions the rear control arms to operate within a corrected radius. This system drastically reduces the feel of bump steer/axle steer on lifted Jeeps and provides handling characteristics comparable to, if not better than, a stock-height Jeep. The DB3 control arm system provides rear upper and lower mid-arms made of thick 1.625" DOM .25" (1/4") wall steel and 1.5" DOM .1875" (3/16") wall steel with strength that can take abuse, with forged threaded ends for the ultimate in durability.

The Rear Long Arm option 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" .1875" (3/16") wall 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 without catching. This system is for the off-roader who demands precision when it comes to wheelbase and pinion angles. MetalCloak's Rear Long Arm features our best high-speed handling properties for on- and off-road and will slightly increase a CTI score over a similar-height DB3 system.

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

MetalCloak True Dual Rate™ Coils provide 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 by worn factory parts. It fits in the 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 provide a smoother ride while also improving the vehicle's 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 Jeep's axle centered and you going in the right direction.

The Drag Link is placed on top of the steering knuckle and comes with a relocation bracket that raises the track bar to eliminate bump steer by correcting the steering geometry in your Jeep JL Wrangler. MetalCloak's tubular 1.375" OD .375" (3/8") wall DOM bar is matched with 1-ton, specifically designed, anti-flop ends that maximize performance and durability.

The Drag Link comes with a strong, CAD-designed and welded 3/16" hot rolled steel plate track bar and stabilizer bracket that increases strength and matches the corrected geometry of the flipped drag link to provide the best steering geometry for your lifted Jeep.

We offer a choice in shocks; run the shock setup you choose to fit your build needs. If you have a different idea of what shocks will work best for you, go for it. MetalCloak suspensions ARE designed to optimally be used with the patented MetalCloak 6Pak™ Shocks for maximum up and down travel. Our RockSport Shocks (Exclusively at MetalCloak) provide the next longest travel you can get with the simplicity of a standard shock and share the same valving as 6Paks; this is a great option if you're looking for a no-maintenance option at a great price. The choice is yours to buy the suspension with or without shocks; we recommend our specifically tuned shocks, but we leave the choice up to you.

Adjustable-height front and rear bump stops are a MetalCloak first and allow you to tailor the travel to the size of tire you have chosen. Add or remove bump stop 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 37" tires, full body armor and suspension lift.

Note: Fitment for 2026 models has not been confirmed.

Note: 6Pak Shocks are not shipped outside of North America. If you are outside of the USA or Canada and order 6Pak shocks or any kit with 6Pak shocks, you are waiving the rights to the lifetime customer service and manufacturer's warranty.

Note: Due to the long travel MetalCloak suspensions provide, factory driveshafts will contact OEM components and wear quickly 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.

Note: RockSport Black Shocks are LARGE-BODIED 2.5" diameter long-travel shocks. Specific brackets are provided for mounting, depending on axle type: Rubicon/Max Tow (wide-track axle) or Sport (standard axle width). Correct wheel backspacing IS required.
