Technical
Coilovers use 46mm pistons and 53mm shock housings, the enlarged shock cartridges with specially designed pistons and rods provide a wide range of damping force.
Valves are constructed of special spring steel, which outperforms stainless steels and produces longer valve life. Valve stacks use a patented deflective system to provide more precise control.
Patented concave lower locking ring, to prevent unseating.
Springs are made of SAE9254 high strength, durable steel. Compression tested at over 500,000 tires with less than 5% deformation.
T6061 Aluminum utilized in spring locks and seats for high strength and lightweight.
Iron lower brackets on MacPherson struts to ensure rigidity.
Piston rods are constructed of highly polished steel to lengthen oil seal life and prevent leaking.
High pressure inner rod guide seals ensure a perfect fit for consistent fade resistant damping and long shock life.
2 step coating process utilizing nickel and chromium plating to prevent corrosion.
Newly developed lubricant oil in shock cartridges minimizes aeration and cavitation
An additional bearing beneath each pillowball mount provides the smoothest action and prolongs the lifetime of the pillowball itself.
