True Dual-Rate Coils with front anti-bow coils are supported with massive lower coil-correct captures with additional polyurethane upper coil capture/isolators for the smoothest ride available.
You have a choice in coils in the rear depending on what you want your truck to do. Choose either the Maximum Articulation True Dual Rate Lift Coils for the best off-road flex OR reuse the factory rear coils with the provided MetalCloak lift structure to match the height to the front and still retain the factory towing specs for hauling.
Massive, Kevlar infused Duroflex joints are housed in Adjustable Forged Ends that thread into strong 2in OD DOM Control arms for amazing flex and NVH (noise/vibration/harshness) capabilities along with maintenance-free durability you demand for your truck.
Front and Rear Track bar brackets are made of thick 1/4in steel plate for a "no compromise" mount that also adds additional support mounts over factory for even more increased strength.
Geometry corrected, forged pitman arm adds strength and matches the geometry of the track bar to the drag link for effortless, worry-free steering control.
Front and Rear bump stops towers reposition the factory parts to function correctly for the added lift height.
This is a complete Game-Changing suspension system that will provide a smoother ride on the road and additional performance off--road. Work or play enjoy the Gold-Standard the MetalCloak Ram suspension provides.

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.

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, 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.

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; this keeps coils aligned eliminating coil bow.
Front Track Bar Bracket
Front Track bar bracket is made of thick 1/4" steel plate for a "no compromise" mount that also adds additional support mount at the cross member for increased strength and durability.
Rear Track Bar Bracket
Rear track bar drop bracket 1/4" THICK!!!! captures axle tub for extra strength with additional gussets for max strength: Rear Track bar brackets are made of thick 1/4" steel plate for a "no compromise" mount that also adds additional support mount at the axle tub for even more strength.
Bump Stop Towers
3/16" 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.
Pitman Arm
Eliminate bump-steer: Geometry corrected, forged pitman arm adds strength and matches the geometry of the track bar to the drag link for effortless, worry-free steering control.
