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, hard-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 anodized 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.
Whether you're a weekend explorer or a frequent trail driver, RockSport BLACK Front Coilovers for the Bronco 6G deliver comfort, control, and capability.
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.

THE TECH
Front RockSport BLACK Coilovers
RockSport BLACK Remote Reservoir Adjustable Coilovers
The RockSport BLACK Remote Reservoir Coilover Shocks are height-adjustable and engineered to conquer demanding terrain with precision, strength, and style. Designed, tested, and built in the USA, these high-performance front coilovers deliver a smooth, controlled ride whether you're crawling rocks, navigating desert trails, or daily driving.
RockSport BLACK Coilover Reservoir
Each coilover features an adjustable remote reservoir constructed from hard-anodized aluminum, finished in a durable black Infinity coating for superior corrosion resistance and a sleek, low-profile look.
Easy 8 Setting Compression Adjustment
A large, easy-to-grip billet knob with laser-marked numbers makes compression adjustment simple. Choose from 8 settings, with each click adding 15% compression force, to tune your Gold Standard. Dial in off-road comfort along with great daily driving performance.
Braided Hydraulic Hose
The remote reservoir connects to the shock through a stainless steel braided hose with a synthetic lining, natural rubber exterior, and 3,000 psi working pressure rating. Oversized flow orifices allow unhindered shock oil flow.
RockSport BLACK Parabolic Valving
Parabolic Valving
Parabolic valving (Patent Pending #63/743,954) provides precise fluid flow in a compact piston stack. Machined parabolic forms contour the butterfly valve shims under fluid pressure, creating variable resistance based on the applied load for refined compression and rebound tuning.
Piston Compression Ports
The multi-port piston uses nine ports to distribute fluid pressure evenly across the butterfly valve shims: six for compression and three for rebound. The shock piston features a functional Type III Mil-Spec clear hard-anodized finish for long-lasting performance.
Inner Recessed Cap
Our completed package maximizes usable shaft length and provides more travel than similarly sized coilover shocks. The end caps are internally machined for additional travel. A removable bump cap protects the seal assembly from damage at full compression and provides access for servicing.
Oversized Chrome Shaft
Oversized 7/8" hard-chrome-plated shafts are induction-hardened to a surface hardness of Rockwell C 60+ for durability. Their tough surface resists damage from rock debris and provides a smooth, consistent interface for the seals and wipers, improving longevity.
