Anti Roll bar to Chassis Mounting Bush Kit The forces applied to the anti roll bar on your vehicle while cornering should in an ideal world be directed though the bar itself, however some of the force is inevitably going to be absorbed in deforming the supporting bush. Using our SuperPro polyurethane bushes minimises this effect, allowing the anti roll bar to do its job. This in turn gives your car much sharper and stable handling. These bushes are available for bar sizes 19, 30 and 35mm; please specify you cars bar size when ordering. This bush kit includes 2 bushes and assembly grease and includes SuperPro's unrivalled 3 Year/36,000 Mile warranty.
