Fenix 1-piece differential joint for Formula cars

Italian company Fenix Racing introduce a 1-piece differential shaft for 1/10th scale Formula 1 cars. Made for Tamiya-style 6mm rear axles the part is machined from 7075-T6 aluminium and it offers a longer thread to allow the use of taller M4 self locking nuts. This in turn improves reliability and allows to use a larger number of diff springs. To minimise weight the contact area for the inner diff plate has been milled down to the smallest possible diameter while the precise machining of the whole parts ensures super true running.
