Every Karter should have a set of these in their Tool Box.
While the idea is not new we have decided to make these as there is no doubt that when the track is very wet getting your front track out wide is a definite advantage.
These extensions screw directly onto the end of your existing stub axles and extend the spindle 40mm. and fit most stub axles, e.g. Arrow, Monarco and most others with a 17mm. spindle.
They are made from the exact same high grade steel that is used for the manufacture Excavator buckets and come with the extra spacers required.
