Sway bars, stabilizer, anti-roll bars' they are all the same thing. As the name suggests their objective is to reduce sway, or bodyroll, and stabilize a vehicle under lateral (cornering) forces. Formula 1 cars still use sway bars along side the shocks and springs as it is the ONLY suspension component principally designed to control body roll. Manufactured in Australia using the finest grade Australian spring steel, they are powder coated and supplied with high performance polyurethane mounting bushes in a DIY kit form, ready to simply bolt on. The fitting of bigger swaybars is still the best dollar for dollar handling improvement you can make.
