Our propshaft remains smooth at critical higher speeds. This balance is retained by 2 main factors. Technology to balance the entire unit and quality tube which is true and stiff.
When we carried out our propshaft development, we experimented with “tube in tube” systems and discovered that they make absolutely no discernible difference to NVH. The reason for this is very simple – in order to be stiff enough to transmit torque using such a small cross sectional contact area, they are in effect a solid propshaft. We also quickly discovered that they have a significant inherent weakness – the two tubes can slip against each other under high torque loads such as standing starts, immediately resulting in a huge imbalance.
Note that you will need to machine your 3-eared Alfa gearbox output spider in a lathe to be a snug fit to our aluminium adaptor. If you do not have this facility, please send us your gearbox drive spider for modification when you order the kit from us. The Alfaholics Race Prop Shaft uses the later (1968 onwards) centre support so earlier cars will need to be modified to fit this. The rear flange is drilled for 8mm bolts so will need to be modified to fit the 2000 type axle.
