The RockSport BLACK Remote Reservoir Adjustable Coilovers feature 2.5" diameter aluminum bodies with 3/16" wall thickness and a large fluid capacity to help keep them cool during on- and off-road use.

Each shock features a remote reservoir with eight-position compression adjustment. Constructed from hard-anodized aluminum, the reservoir has a durable black Infinity finish for superior corrosion resistance and a sleek appearance. It connects to the main shock body through a stainless steel braided hydraulic hose with a 3,000 psi working pressure rating. Gold zinc-plated mounting brackets made from 1/8" hot-rolled steel provide a secure fit built to withstand demanding trail use.

A billet aluminum knob provides eight compression settings, with each click adding 15% compression force. Dial in your suspension for on-road comfort or firmer off-road control.

Inside the coilover, a patent-pending (#63/743,954) parabolic valving system causes the butterfly valve shims to contour under fluid pressure, creating variable resistance that adapts to different loads. The result is a refined damping response that balances comfort and control.

The high-flow piston features nine ports: six dedicated to compression and three to rebound. These ports are tuned to optimize fluid flow throughout the coilover stroke. The recessed inner cap allows the piston to travel into the cap itself, maximizing usable travel without increasing overall shock length.

An oversized 7/8" induction-hardened, chrome-plated shaft provides durability, with a surface hardness of Rockwell C 60+. This tough surface provides a smooth, consistent interface for the seals and wipers, improving longevity and reducing wear.

Coil spring preload can be adjusted using the gold zinc-plated collars, allowing you to dial in ride height and preload for your setup. Each front coilover includes large, heavy-duty lower bar pins for secure mounting.

Made of thick 3/16" steel, the fully welded Bronco A-arms increase suspension droop by providing additional clearance between the A-arm and the coilover spring.

The Bronco A-arms feature heavy-duty uniballs for increased strength and durability over factory ball joints. These 1.25" uniballs are made from precision-ground, heat-treated, hard-chrome-plated steel with a Teflon lining.

Durotrak™ A-Arms feature additional caster and an adjusted camber curve for lifted applications from 1" to 3". MetalCloak's uniball upper control arms help restore proper alignment and improve the handling characteristics of your lifted Bronco.

The uniball cup and pinch bolt system prevents play between the cup and bearing while allowing servicing without removing the A-arm.

A laser-engraved “M” dust cover adds style and protection from the elements to help extend uniball service life.

MetalCloak Bronco A-Arms are equipped with patented two-piece Durotrak™ bushings for noise, vibration, and harshness damping. Made from a proprietary elastomer compound unique to MetalCloak, the bushings thread together for simple installation without a press. They reduce vibration and harshness transferred to the driver and improve steering response.

MetalCloak Bronco 6G Rear Duroflex™ Control Arms feature one of our best innovations in suspension components. Our patented (mcpatents.com) Duroflex Joints are designed to stay centered and aligned with the frame and axle for long-term performance. Strong DOM tubing is carefully formed for tire clearance and durability.

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.

These control arms feature Duroflex™ Joints, the only vulcanized elastomer, self-centering joints enhanced with DuPont™ Kevlar® fiber. Exclusive to MetalCloak, they provide incredible durability, greater control arm misalignment, and better vibration damping than anything else available. See the technical section for more details.

The Durotrak™ adjustable rear track bar for the Bronco 6G features patented Durotrak™ two-piece bushings at both ends of a solid 1.25" OD 4130 chromoly bar. The bar is finished in gold zinc for the ultimate in durability against the elements.

MetalCloak “components” have been proven safe with the FMVSS certificate of safety configured with 37" tires, full body armor and suspension lift.

The Bronco Suspension System is finished in MetalCloak’s signature gold zinc and is made right here in the USA.

Note: We recommend you have a suspension specialist align your Bronco once a MetalCloak suspension is installed.

Note: Replacement of the Bronco rear control arms requires the removal of the gas tank.

Note: Lift height ranges from 2.5" to 4", depending on the Bronco model and whether it has the Sasquatch package. Limitations of factory or aftermarket equipment determine the proper settings for best performance. Improper setup can damage your vehicle.
