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