Arnott’s completely new coil over struts are built using quality components including custom-valved internal shocks and new steel coils. These coil over struts are engineered and rigorously tested on dyno machines and driven countless miles on Arnott’s fleet of test cars. Arnott-designed struts are an excellent passive alternative for aging air or electronic suspension systems restoring comfort by replacing the OE shock with a completely new custom-valved coil over strut to provide a great ride.
