Use this kit to rectify a steering pull after a vehicle has been aligned to the manufacturer's specifications. Supplied with an offset bush to be fitted to the passenger side and a standard bush for the driver's side, these kits stagger the caster or setback by re-positioning the ball joint slightly forward in the chassis. This is a non tire wearing geometry change that has a substantial effect on a vehicles ability to track straight and other handling characteristics. Follow the installation instructions and the problem is solved.
