SuperPro MINI 26mm Adjustable Front Anti-Roll Sway Bar RC0045FZ-26 R55 R56 R57 R58 R59

SuperPro bars have a polymer coating, meaning they are designed for European road conditions, and stones simply "bounce off" rather than chip the normal powder coated finishings of other bars. SuperPro have two demo cars that have had bars fitted for over two years, and they still look as good as new.

SuperPro sways bars are Cold Formed Roll Bars - Bars that are made in this process are made from XK5160RP Spring Steel. This is a medium to high carbon-chromium spring steel possessing high hardness used predominantly in manufacture of coil & leaf springs. Cold forming of these sway bars does not alter the mechanical properties of the material, so therefore no heat treating process is required. In addition, the steel used in this method is best suited to be cold bent and the mechanical properties are the same as the hot formed bars after heat treatment.

SuperPro choose the best material for the given manufacturing process to achieve the best outcome. When stamping and forming the ends of our cold bent bars SuperPro keep our forging temperatures as low as possible to avoid altering the mechanical properties of the steel. This process is made much easier by using an induction heater.

With over 4000 hours of Salt spray testing and no degrading of the surface finish, this highlights another superior feature of SuperPro Roll Control Sway Bars.

Supplied with the required bushes, which fit with the OEM anti-roll bar brackets.
