Polybushes and Four Wheel Drive Vehicles go together like Peaches and Cream. Four Wheel Drives really use their suspension (with poor roads and speedbumps, even the school run is starting to resembe the Sahara) so you need bushes which will withstand years of twisting, bumping, vibrating, braking and accelerating. What you don't need are bushes which move, rattle or crush causing knocks, creaks and eventually wear to their housings.
Welcome to the world of Polybush! Each bush is tailored to fit beautifully and contribute to excellent handling. The bonus is, Polybushes will give you the same ride quality long after their rubber or cheap urethane counterparts have sagged or split.
You can go even further. There's a standard kit for most vehicles, but Polybush can manufacture in three different grades of urethane. So owners can tailor handling by buying part kits in varying grades to special order.
