Thread: Aluminium driveshaft suppliers

I would talk to Harrop about it. They can provide serious and fully engineered solutions for serious vehicles. Obviously not going to be cheap, but will do the job .

We shortened one at work for a '32 ford, sure he said was a late model falcon shaft???

Give hardy spicer in newy a call.

My BF Falcon ute has an alum tail shaft std.

Interesting.
The shaft is for the 300zx. It has a factory 2-piece unit with centre bearing that has **** the bed after 28 years of punishing service. I am looking to make it a 1 piece for simplicity.

I spoke to a gearbox place today (MTF, rick) off chance that they could recommend a place... but to no avail. The guys there mentioned what I was chasing was similar to a non specified falcon with a similar CV end and slip yoke combo... but I'm yet to get any measurements of mine to see what I need. If I could get an alloy 1 piece falcon part to work with minor mods, it'd be payday...

I might be stating the obvious Mitch, but Retorque in Barnes St do make tailshafts - Laurie

Hey Mitch, had any luck with this?

Not wanting to dampen your enthusiasm, but a few things to consider...
Car companies hate spending money unnecessarily (I know, I work for one!), so if the original propshaft design was 2 piece, it's probably because engineering a single piece was too hard.
A single piece prop will lower the first bending mode of the entire driveline, increase the hung mass on both the gearbox and rear diff and probably increase noise and vibration. More importantly it potentially has implications on top speed. If the bending mode gets lowered significantly, you run the risk of getting into the first resonant mode of the propshaft at high vehicle speeds. Seen this happen. Not pretty!

The single piece Falcon prop was at the time I think the longest single piece prop going (certainly in Ford) and had a significant effort into mass, diff gearing, tyre sizes etc. to make sure it worked.

No idea about 300z driveline, tyre sizes or gearing, so it might work. You might just have to put up with more noise/vibration and a lower top speed! Probably cert/engineering implications too. Unless there is another variant of 300z that already has a single piece prop?

Stock Falcons are also speed limited to 180KM/H due to the aluminium tail shaft if this matters. Not sure what the XR8 and FPVs had fitted.
