Arnott’s completely new coil over struts are built from the ground up with quality components including custom-valved internal shocks and new steel coils. These coil over struts are engineered and rigorously tested on dyno machines and then 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.
