Features Include:- Front Lock-N-Load™ Radius Long Arm
- High-Misalignment (NVH) Duroflex™ Control Arms
- True Dual Rate™ Coils
- Front & Rear Durotrak™ Bushing equipped track bar
- Track Bar weld on bracket
- 3 Piece High Clearance belly pan
- Adjustable bump stops
- Drop Pitman Arm
- 3 layer Stainless Steel extended Brake lines
- Specifically Tuned Shocks for True Dual Rate Coils
- Made in the USA
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 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.
3 Piece Belly Pan is designed for abuse and engineered to be the best. Front and rear departure and approach angles, boat sided, solid design stiffens the chassis, clearance for stock or aftermarket transfer case, and the center section may be removed to allow servicing of protected components.
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. 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 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 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.
Every aspect of clearance has been taken into account with angles and skids built into the carefully developed components. Weld-on and bolt-on pieces transform the Jeep Wrangler into a well-mannered street driving machine and an all-out high-performance rock crawler for off-road.
MetalCloak “components” have been proven safe with the FMVSS certificate of safety configured with 37" tires, full body armor and suspension lift.
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 manufacturers warranty."
Note: This Kit Requires Welding at the rear axle.
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: Exhaust modifications will be required for proper fitment.

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.
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.
The Duroflex Joint Provides The Best Ride. Period.
Made of a Proprietary Elastomer Compound, the High Vibration Dampening and Self-Centering characteristics of the Duroflex Joint means you will always get...
- The best ride quality
- No binding of your control arms.
- None of the micro-wear that DESTROYS Flex Joints
High Misalignment...
By adapting the High Transverse Flex characteristics of a typical Flex Joint, the Duroflex Joint gives you...
- Over 34° of Misalignment
- Over 68° per Control Arm
Absorbs Micro-Movements...
Because the Duroflex Bushing absorbs the millions of Rotational Micro-Movements found in your daily driving, you get...
- Improved Ride Quality
- None of the micro-wear that DESTROYS Flex Joints
True Bearing Surface...
The outer surface of the Duroflex Bushing acts as a bearing, breaking free when called for, giving you...
- Maximum Rotation & Articulation
- No "Binding Up" of the Control Arms
Low Maintenance & Rebuildable...
Unlike typical Flex Joints, the Duroflex does not require replacing key parts every year like others...
But, when you do need to rebuild it, it is MetalCloak Easy!
Just pull out the Duroflex Bushing, clean it up, add some new Teflon impregnated, synthetic silicone grease. Reassemble.
Done.
Forged for Strength...
The adjustable threaded ends are Forged providing a 37% higher fatigue strength over inferior cast parts, this EXTRA rock bashing strength will hold up to whatever you throw at em.
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!
Lower Front Long Arms
Both the Front Radius Arms and the Lower Rear Hi-Clearance Arms are manufactured for the ultimate in strength and versatility.
- 2" x .25" wall DOM
- Signature Gold Zinc Chromate
- Oversized Duroflex Joints at the Belly Pan
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.
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 without reliving stress on the bushings and brackets that will provide 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.
The 4-Link Rear Perfected
While the Radius Arm front was ideal, we realized the space in the rear allows for a properly engineered 4-Link.
Choosing the 4-link rear control arm design provides added torque strength support for the main drive axle and provides a fantastic overall ride quality.
Our design eliminated the typical unsteady "Long Arm Roll" felt on a lifted TJ/LJ while cornering - and that's without running a rear sway bar!

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