Upper front arms are comprised of 1 adjustable control arm made of 1.25 DOM X 3/16 tubing and the patented adjustable Lock-N-Load that performs as a standard "solid control arm" when locked, but when unlocked "or loaded" it allows for the axle to slightly move forward or backward to remove stress on the bushings and brackets; this provides a longer service life and directly equates 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. Front end system is engineered to match perfectly to our rear bolt on long arms.
Rear Long arms DO require removal of the factory rear control arm brackets but DO provide the BEST working geometry that MetalCloak has to offer; the angles offer better acceleration response with the least wheelbase change and provides premium handling at higher speeds.
The Lower Rear Long arms are made of thick 2.0 DOM .25 (1/4) wall steel that provide strength that can take abuse with forged threaded ends for the ultimate in durability.
Upper rear control arms are 1.5DOM .1875 (3/16) and formed to provide clearance for up and down travel. Upper and Lower Rear Control arms utilize our patented Duroflex bushings for bind free, service free articulation.
Every aspect of clearance has been taken into account with easy to install 100% Bolt on Rear Long arm brackets that are made strong with fully welded ¼ inch steel plate and features angled surfaces to slide up and over obstacles.
Combining technologies with True Dual Rate™ Coils, revolutionary DuPont™ Kevlar® fiber enhanced Duroflex™ Joints, and the 2 piece Durotrak™ bushing equipped Track Bars and you have a system that is unmatched in the off-road industry.
This Long arm system is easy to install and comes complete with every thing you will need: front and rear long arms, shocks, track bars, and steering stabilizer, brake lines, bump stops and all the hardware needed. Fitment is precise and performance is premium.
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: 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: Front and Rear driveshafts required.
Note: Exhaust modification may be required on all 2007-2011 JKs to install this kit to clear the lower front control arm mounts
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.
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.

Duroflex Joint Revealed
The MetalCloak Duroflex Joint gives better dampening properties over OEM style rubber Clevite Joints and provides more misalignment than “other” inferior Flex Joints.
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.
True Dual Rate Centered Coils 101
This short video covers all you need to know about MetalCloak's True Dual Rate Centered Coils.
Durotrak™ Bushing
Eliminate squeaks and clunks in your steering with the technology of MetalCloak’s Durotrak™ bushings; exclusively found in MetalCloak track bars.
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.
What is Corner Travel Index?
Since 2014 MetalCloak has tested thousands and thousands of rigs at events all across the county collecting specs on the build and cataloging the results. The data collected allows us to make our own products better.
FMVSS 126 Compliant

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.
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!
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.
Threaded Forged Ends
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.
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.
