Shocks are made with 2.5 diameter, 3/16 thick wall aluminum providing extra protection for the vital internal components with a huge interior for fluid to ensure they stay cool and hold up to on and off-road abuse.
The Remote reservoir connects to the shock with a 3000psi high working pressure, stainless-steel braided, synthetic lined reservoir hose, with optimized flow orifices to allow unhindered shock oil flow.
Unique valve stack with Parabolic shim-form (Patent Pending #63/743,954) provides a compact and simplified valve assembly that eliminates shim stack problems of conventional methods, allowing for our exacting target numbers to be achieved.
Our completed package allows for maximum shaft length to be utilized and provides more travel than any similar size Monotube shock; even the internals of the end caps are machined out for additional travel.
Functional Type III Mil-Spec clear HARD anodized process is used on the shock piston to keep the assembly from wearing down from the high velocity fluid transfer, ensuring a long lasting service life.
Oversized 7/8" hard chrome plated shafts, induction hardened to Rockwell C 60+, exceeding most competitors in durability and can take a beating over and over providing the BEST protection from rock debris; this allows a consistently smooth surface for seals and wiper to ride on.
A triple seal pack keeps shock oil in and contaminants out. Removable Bump Cap protects the seal assembly from full compression damage and provides access for servicing the shock.
Large, easy to grip billet knob with laser marked numbers allow you to change the compression setting simply; choose from 8 settings that add an additional 15% compression force at each click to tune in your Gold Standard. Dial in your off-road comfort along with great daily driving performance.
Shock attaches with built-in off set mounts that allow for long travel capabilities with the convenience of an OE like fitment.
The RockSport Black Shocks come with a 1/8", Laser Cut, gold zinc finished reservoir mount.
RockSport Black Reservoir Shocks provide a high end shock with adjustable compression settings allowing you to dial in your Grenadiers ride for fantastic performance with a comfortable yet stable compression and rebound cycle for Rock Crawling, Overlanding, Daily Driving or “spirited” off-road navigation.
MetalCloak changes the game when it comes to coil springs, we offer the ONLY True Dual-Rate™ Coil Springs for the Grenadier. Our exclusive coils provide the longest extended length available providing stability at the extremes of articulation while offering amazing on and off-road handling along with great load carrying capabilities.
Kevlar infused Duroflex joints are housed in Adjustable Forged Ends for maximum strength that thread into strong 1.625 OD DOM Control arms for the adjustability you need when correcting pinion angles and castor. Duroflex joints have over a decade of documented success providing amazing articulation and better than stock NVH (noise/vibration/harshness) capabilities along with maintenance-free durability for your Ineos.
The Durotrak adjustable front and rear track bars for the Grenadier add strength for off-roading while also allowing the axles to be centered after modifying lift height. Durotrak Track Bars are built with MetalCloak's Patented Durotrak 2 piece bushing and assembled into forged CNC machined housings; housings are fastened to SOLID 1.375 OD 4130 chromoly bar for undeniable strength. The full assembly is finished in our signature gold zinc for the ultimate in durability against the elements.
MetalCloak's Adjustable Bump-Stop System is designed so you can dial in the exact amount of bump stop for the tire size you choose. Easily add or take away the stackable pads to get the perfect amount of bump-stop needed maximize your suspension travel while setting limit to keep tires from hitting vital components. Can be adjusted without removing coils.
The MetalCloak Rear Bump Stop Extensions for the Ineos Grenadier are engineered to perfectly to work with the RockSport Black shocks. Precision machined from durable Delrin, these extensions drop the bump stop 2” to maintain proper up-travel limits when running longer shocks and ensure maximum use of the allowable travel.
Each kit also includes MetalCloak’s DuroSpring™ replacement bump stops, providing a softer, controlled stopping point when reaching the limits of compression that enhances ride quality and durability both on and off-road.
This suspension lift will provide a smoother ride on the road while maximizing performance off-road. Work or play enjoy the Gold-Standard the MetalCloak Grenadier suspension provides.
Note: We recommend you have a suspension specialist align your Grenadier after MetalCloak suspension upgrades have been Installed.

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.

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.

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.(Learn More About Durotrak Track Bars Front / Rear)

Solid Chromoly front track bar keeps you... well.. on track
Formed for ultimate Up-Travel & Down-Travel for the Ineos Grenadier. Front and Rear Track Bar gives adjustability and unprecedented strength, clearance and improved ride stability. These components provide additional strength for off-roading and will allow the axle to be centered correctly when altering the lift height.

What are True Dual Rate Coils?
MetalCloak JL 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 Front / Rear)
