Fortune Auto Dreadnought Pro 2-Way Coilovers - 1989-1994 Nissan 180SX (S13)

Fortune Auto engineers are consistently chasing improvement and the development of the Generation 8 – Dreadnought Pro 2-Way damper is no exception.

The Dreadnought Pro 2-Way double adjustable coilover for the 1989-1994 Nissan 180SX (S13) is a remarkably sophisticated damper system. Utilizing the highly advanced, Concave Flow Digressive Piston to provide an incredibly dynamic adjustment range along with the ability to upgrade and rebuild; you'll never have to buy coilovers again.

Generation 8 Updates

Laser Etchings: The most easily identifiable, external detail on the Generation 8 will be the new laser etched top plates, locking spring perches, and lower mount locking rings. Labeled with hex key sizes to make the process of setting up your coilovers even easier.

Lower Mount Locking Ring Clamps are now standard – easier to adjust and less prone to coming loose in high mechanical grip applications.

Revised Concave Flow Digressive™ Pistons for the 510 Series, Dreadnought Pro 2-Way, and Dreadnought Pro 3-Way applications. The renowned CFD Piston is now updated to the 6XXX Alloy Series. With optimized high flow valves, the efficiency and capability of the motorsports line of coilovers has never been better.

No Revalves Necessary

The ultra wide range of adjustment offered by the CFD piston allows for the convenience of tuning your suspension without having to revalve your dampers. A conventional shock absorber can withstand a 2kg spring rate difference before requiring a revalve, whereas the Concave Flow Digressive Technology has a broad range of 8kg spring rates. This is invaluable for tuning your suspension quickly at the track on race day.

Jekyll and Hyde

The Concave Flow Digressive Piston allows for a Jekyll and Hyde personality. Lower spring rates can be stiffened up by using the wide damping range as an artificial spring rate, while higher spring rates feel much smoother. The large adjustment range contributes to a comfortable ride on the street and unyielding performance on the track, all with the twist of a single adjustment knob.

Bright Dip Anodized

Bright dip anodizing is a chemical polishing/anodizing process that is very effective in enhancing the integrity of the aluminum. Bright dipping creates a brilliant, shiny surface which protects our 6061 forged aluminum parts from corrosion and oxidation, ensuring that your parts look great for years to come.

Radial Bearing Mounts

The high quality Koyo Japan radial bearing provides less bind for noise-free operation and smoother steering response.

Back-milled Aluminum Components

Aluminum components on the Generation 8 series coilovers are designed for optimal efficiency by maximizing weight savings without compromising integrity. Radial Bearings are back-milled along with completely redesigned spring perches, standard locking spring perches, aluminum camber bolt sleeves, and bow-tie style aluminum pillowball housings. Almost all components are now lighter and showcase a more elegant design.

Dyno-Tuned and Tested

EVERY Fortune Auto shock absorber is dyno-tested. Once your shock absorbers are built, they are tested and matched, because we refuse to treat our shocks with a "one size fits all" mentality.

Premium Chrome Silicon Springs

The Generation 8 line of suspension are equipped with premium chrome silicon springs. Made with a special premium alloy that offers superior performance, longevity, and ride quality.

Concave Flow Digressive Piston Technology™

Concave Flow Digressive Piston Technology allows for a Jekyll and Hyde personality. The large adjustment range contributes to a comfortable ride on the street and unyielding performance on the track. The tremendous amount of low speed force translates driver inputs into razor sharp control. Furthermore, the force "blows off" to provide the driver with a supple compliant ride while maintaining superior mechanical grip over rough surfaces.
