Factory Tailshafts

Search found nothing.

As this doesn't appear to have been discussed much I assumed the tailshafts are pretty strong.

I'm doing an r33 box into r32 conversion and have to change the slipyoke over.

One shop I went to said they never replace the staked unijoints and I would have to have a completely new tailshaft made.

They said the factory ones were weak anyway and that the replacement unis were even weaker.

How much power can the stock tailshafts hold?

Is a one piece better or do they have other issues?

from my limited knowledge i understand that when moving to a 1 piece it needs to be balanced spot on otherwise you will suffer vibration problems and even gear selection problems. other than that if you know somewhere trustworthy that can make you one i say go for it.

Ive heard of many problems getting custom ones made up. I'd retain as much of the factory one as you can and get one end modified etc. You need to get it balanced.

I was just wondering at what power level does the factory tailshaft start having problems?

[benl1981]

I haven't heard of them being a weakpoint - wouldn't imagine any less than 300 - 350rwkw

- somebody with experience may be able to help

I run a 1 piece tailshaft with a 33 box in my 32. Setup has run over 300rwkw, and an 11 sec 1/4 from previous owner. I put it in my car behind a 3lt, and it still has no probs with vibration, or gear selection...

I just fitted the r33 slipyoke to the r32 manual tailshaft using

a hardy spicer unijoint.

I can see what the guy meant about the replacement joints not being as strong as the original ones.

The cross piece in the centre is not as thick as the original.

Has anyone had trouble with the replacement joints failing?
