    Suspension bushings are the link between your vehicle and its springs, struts and shock absorbers. Suspension bushings provide the movement and/or mounting points in your vehicle’s suspension system. Hence these suspension components can influence both the ride quality, steering feel, as well as the grip of the tyres, performance of the brakes, and stability of the shock absorbers. Should these suspension components be worn, an unpredictable and more to the point unsafe motor vehicle can be the result.Benefit Note: Whiteline's 'Vehicle Essential Kits' contain all the essential components to 'Activate More Grip'.

    Ideal for bushings, bearings, spherical joints or other applications. Can be used on workshop press or better yet on car simply and easily. Less force required to remove / install bushings, bearings and joints making use easy even without power tools Benefit Note: Most old and new suspension bushings are pressed in and out with old bearing shells, sockets or just anything you can find. This creates a safety issue, given that heat treated steel will shatter under stress. The assortment of sleeves that make up the Nolathane Press Tool Kit are made from mild steel to allow distortion or crush when over-pressed. These newly designed tools provide an easy way to install and remove Whiteline polyurethane bushings and aid in other workshop pressing requirements.
