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.
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.

THE TECH
So what's in the kit?
- Front Lower Long Arms
- Lock-N-Load or Radius Control Arm
- Front Upper Radius Control Arm
- Rear Duroflex Control Arms
- Front & Rear True Dual Rate™ Coils
- Front Coil Perches
- Front Track Bar
- Rear Track Bar
- Front Bump Stops
- Rear Bump Stops
- Front Sway Bar Links
IT ALL STARTS WITH THE BUSHINGS
The Patented Duroflex™ Joint (metalcloakpatents.com) is the key to getting the greatest flex in a Ram 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, Self-Centering, Rebuildable Joint with an OEM quality ride.
The Duroflex Joint Provides The Best Ride. Period.
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.
FULL SIZE Strength
3" Duroflex Joint for the RAM Truck; these joints are HUGE! Take all the benefits of maximum articulation, unlimited rotational range, the best NVH (noise/vibration/harshness) and combine that into a service free bushing infused with Kevlar. These joints are made specifically for FULL SIZE strength.
Lower Front Radius Long Arms
Engineered for ultimate clearance including both Up & Down travel under your Ram.
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.
Has unparalleled on-road handling characteristics that some say are unprecedented in a suspension system.
Optional 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 eliminating stress on the bushings and brackets providing 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.

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)
Front RAM True Dual-Rate anti-bow springs do not neck down like 'typical coils" and alleviates coil bow as the additional support from the larger diameter coil maintains structure and provides better performance.
Front Upper Spring Capture/Isolators
Polyurethane Front Upper Spring Capture/Isolators capture MetalCloak RAM True Dual Rate coils and isolate NVH (noise vibration and harshness) while keeping the coils centered.
Front Lower Coil-Correct Captures
Strong 3/16" .120 wall steel Front Lower Coil-Correct Captures work in conjunction with MetalCloak True Dual-Rate Ram Front coils to center, angle and capture the coil to eliminate coil bow.
Front Track Bar - Forged for Strength
Oversized spherical bearing handles directional load, forged CNC machined bearing housing with off set design ensures maximum clearance.
The adjustable threaded end is 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.
Front Durotrak Track Bar
The Solid Chromoly track bar is uniquely designed to clear on up-travel as well as down-travel AND fit aftermarket housings. No other track bar is designed with this much clearance and up-travel in mind.
Rear Durotrak Track Bar
The Durotrak adjustable rear track bar for the Ram Truck is built with Patented Durotrak 2 piece bushings that are mounted on both sides of the Solid 1.375 OD 4130 chromoly bar. The bar is finished in gold zinc for the ultimate in durability against the elements.
Bump Stop Towers
3/16" hot rolled steel Plate spacer (3" x 3" .188 WALL Steel Tube) Front and Rear bump stops towers reposition the factory parts to function correctly for the added lift height.
Sway Bar Disconnects
When Lifting a Truck the sway bar links also need to increase in length to keep your sway bar adjusted properly. MetalCloak Extended Sway Bar Links bolt directly into the factory locations with no cutting or modification required.
