The Trakrite camber bar allows either of the Gunson camber gauges to be used with the wheels on the vehicle and the vehicle sitting on the ground. It is ideal for alloy wheels when the magnetic base of the camber gauge cannot be attached to the wheel hub. The bar is fully adjustable and can either be hung onto the tyre or held in place by hand to provide a precise base point for measurement. When the gauge is levelled and set up, the camber angle, castor and KPI can be clearly read from the gauge. Designed by Gunson in the UK, the Trakrite camber bar makes it quick and easy to take important measurements, even on alloys. Ideal for quick checking of camber, caster and KPI when used with Gunson gauges, Part Nos. 77099, 77066.The camber bar is fully adjustable for wheels up to 18 inch in diameter and designed to hang on the tyre giving hands free operation. Where the vehicle wheel arch is too low for the camber bar to hang on the tyre it can still be used without the top bracket (held in place by hand). For car and light commercial use.
