Kevlar-infused Duroflex joints are housed in adjustable forged ends for maximum strength. These ends thread into strong 1.625" OD DOM control arms, providing the adjustability needed to correct pinion angles and caster. Duroflex joints have over a decade of documented success, delivering amazing articulation, better-than-stock noise, vibration, and harshness (NVH) performance, and maintenance-free durability for your INEOS Grenadier.

The Durotrak adjustable front and rear track bars for the Grenadier add strength for off-roading while allowing the axles to be centered after modifying lift height. Durotrak Track Bars feature MetalCloak's patented two-piece Durotrak bushings assembled into forged, CNC-machined housings. The 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 durability against the elements.

This suspension upgrade provides a smoother ride on the road while maximizing off-road performance. Work or play, enjoy the Gold Standard that the MetalCloak Grenadier suspension upgrade provides. These components work with the Grenadier at factory height and offer adjustment to support over 3" of additional lift.

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 provides better damping than OEM-style rubber Clevite joints and more misalignment than other flex joints.

Vibration Damping

We tested our Duroflex Joint using a shaker table and a seismometer app to demonstrate its vibration damping compared with other industry-leading joints.

A Comparison of Flex

Compare the flex of the Duroflex Joint with the Johnny Joint, the Teraflex Monster, and a typical Clevite joint.

Durotrak™ Bushing

Eliminate squeaks and clunks in your steering with the technology of MetalCloak’s Durotrak™ bushings, found exclusively in MetalCloak track bars.

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.

Diagram comparing an OEM Clevite joint and a typical flex joint with the MetalCloak Duroflex Joint.

MetalCloak has combined the best features of the most widely used control arm joints to create the Duroflex Joint: a low-maintenance, high-misalignment (34°), self-centering, rebuildable joint with an OEM-quality ride.

Now with Kevlar!

DuPont™ Kevlar® fiber is compounded into the proprietary elastomer of the Duroflex Bushing, bringing even more strength, durability, and performance.

Kevlar® is a synthetic fiber with an extremely high strength-to-weight ratio—five times stronger than steel by weight—and is commonly used in bullet-resistant armor.

Duroflex Bushings with Kevlar® can be identified by the MetalCloak “M” on the outer surface.

Control Arm Duroflex Joint Alignment

At MetalCloak, we take care to build every product right.

Most manufacturers build their control arms misaligned from center. Why? It simply costs less to do so.

Our joints are centered and aligned to reduce wear and improve performance.

It makes them easier to install, too!

Threaded Forged Ends

Forged for Strength

The adjustable threaded ends are forged, providing 37% higher fatigue strength than inferior cast parts. This extra strength helps them withstand repeated rock impacts on the trail.

Meet the Patented Durotrak™ Track Bar Bushing

The patented Durotrak™ Bushing (metalcloakpatents.com) is an NVH (noise, vibration, and harshness) bushing made with a proprietary elastomer compound unique to MetalCloak. Its two pieces thread together, making installation simple without a press. The bushing reduces vibration and harshness transferred to the driver and improves steering response.

INEOS Grenadier Durotrak Front Track Bar

Formed for maximum up-travel and down-travel on the INEOS Grenadier, the front and rear track bars provide adjustability, strength, clearance, and improved ride stability. These components add strength for off-roading and allow the axles to be centered correctly when altering lift height.

Optional Rear Load Spring Spacers

Rear coil spring and gold zinc-coated spring spacer assembly for the INEOS Grenadier.

Rear Load Spring Spacers adjust the rear ride height of your INEOS Grenadier to help maintain a level stance and proper handling when towing or carrying heavy loads within the vehicle’s rated limits. These easy-to-install, fully welded steel spacers help correct the vehicle’s stance under load. A gold zinc finish protects the spacers from the elements.
