Crownwheel & Pinion Sets

£995.00 GBP (ex vat)


New premium quality Alfaholics production, manufactured in the UK to the very highest quality and exacting tolerances. We have taken the opportunity to improve the tooth cut profile for increased strength over the original cut used by Alfa.

These crown wheel and pinion sets are available in the small 1300/1600/1750 size in 5.8, 5.3 & 4.3 ratios. Optimum performance can be achieved by fitting in conjunction with our Alfaholics Limited Slip Racing Differential.

The 5.3 & 5.8 ratios are for intended for circuit racing, whilst the 4.3 option is the optimum ratio for fast road and trackday cars. By using the small size axle, unsprung and rotational weight is kept to a minimum. An additional benefit for those people with fast road & trackday cars, is that you can use the existing axle from your GT Junior and simply fit this 4.3 ratio with LSD, rather than trying to find what are now very rare Berlina 4.3 rear axles.

We can also manufacture to order any desired ratio (in addition to those above) within 3 weeks.
