The R3 Racing Magtronic rear alignment system has been designed to accurately check the alignment of any kart chassis when used alongside the front alignment tool.Using inbuilt strong magnets, the rear alignment system can check for bends, twists and crabbing ensuring that you get the best performance out of your kart and maximising your potential. Made from aircraft grade anodised aluminium alloy material, the unit makes use of a microprocessor controlled laser beam which can either be modulated or sent as a full beam. Capable of fitting onto an axle measuring 17-50mm, the Magtronic rear alignment system will work on a wide range of applications and, with an operating time of up to 70 hours of continuous use, can always be relied upon to provide accurate readings.
