Jeep JK Wrangler 4.5" Game-Changer Suspension & Lift Kit
Our JK 4.5" Game Changer Suspension comes with everything you need to properly provide 4.5" of lift to your Jeep including a complete HD Hi-Steer Kit! MetalCloak's patented technology is unprecedented performance.
Features Include:- Duroflex™ Joints enhanced with Kevlar
- True Dual Rate™ Coils
- Durotrak™ equipped track bars
- Height adjustable bump stops
- Hi-Steer Kit
- Specifically tuned shocks for True Dual Rate Coils
- Designed for maximum UP and DOWN travel
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.
MetalCloak Thermoset Elastomer 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 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.
The MetalCloak JK Wrangler Hi-Steer kit provides a new drag-link that is placed on top of the steering knuckle and comes with a relocation bracket that raises the track bar to eliminate bump steer in your JK that is lifted over 4.5 inches.
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.
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 37inch 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: All 2012+ JK Wrangler will require exhaust spacers (7078) for clearance for the front drive shaft.
Note: MetalCloak does not recommend powder coating your True Dual Rate Coils. See instructions for additional details.
Note: MetalCloak engineers have chosen shocks that have the ideal synergy with our coils. We have not tested other shocks on the market as to whether or not they compliment our suspension system or suppress its performance. In other words, choosing another shock could significantly impact your ride quality.
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.

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.
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!
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.

Degrees of Articulation
MetalCloak's Duroflex Joint provides 28˚ more articulation and flex than typical control arms! (Learn More About Duroflex Control Arms)
What are True Dual Rate Coils?
MetalCloak JK Wrangler 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)
Coil Isolators
MetalCloak Thermoset Elastomer 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.
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.

JK Specific OE Bolt Taper - Secure mount
Anti Flop Feature
Full side to side range of motion ensures bind free steering when pushing the extremes of your Jeeps travel and articulation, while a limited "front to back" range of movement is built into the rod-end and eliminates the possibility of the offset to allow the rod end to "flop".
