TEGIWA 360 Degree Adjustable Shifter Extension. Manufactured here in the UK from 6082 billet aluminium and 303 stainless steel. This shift extenion is as good as it gets with fully customisable adjustability. By clocking the aluminium round you can gain greater car control and by raising the shaft you reduce the time taken to change gear. The height is adjustable from 75-120mm. Optimise your shift experience with a quality short shifter such as Skunk2. To install simply screw onto the M10x1.5 thread and either use the 'OE' locknut or thread-lock to secure.
