I'd say go for it. Never regretted installing mine (1 Piece Aluminium Shaft). The day I installed mine: Link here. Main Thread: Link here. The vibration noise I mentioned is completely gone by the way. Didn't do anything, just seemed to vanish over a short amount of time. Cant remember exact figure but I paid in the neighborhood of $600 landed and delivered to my door? From the US. MoulaZX
My good friend's Uncle was badly wounded by a broken driveshaft that entered the cabin removing his arm and braking several ribs. So yes, pfft safety.

Hi Nigel Does Jeff require the original 2 piece shaft to make the new 1 piece. Does anyone have experience with a 1 piece shaft in a lowered Z, wondering if tunnel clearance is an issue, I think I've just realised that the Diff centre is solid mounted so therefore the tailshaft can't move up and down, would this be correct. Dave
I think the only downside of a 1 piece is that you can get some vibration but this would obviously be partly due to build quality, weight and build material as well. Especially if the shaft is not balanced well. The other thing is to have a catch loop in case the front uni lets go or it completely sheers off from the front, otherwise you may find yourself giving some extra proof to the confirmed myth the myth busters proved of a car catapulting of it's broken drive shaft digging into a pothole on the road and also destroying the boot / rear area of the car Cheers, Craig
A two piece drive shaft is stronger than a one piece and is one of the reason's the zed engineers used it. Someone really needs to make a two piece CF shaft for the zed, that would be a great compromise as it would be stronger than a single piece CF shaft (it would be a bit heavier but thats the compromise for the added strength).
Was it a tube failure or uni or outside it's designed use our race car uses a titanium drive shaft, light but small dia ( approx 32mm at it's smallest point eX sprint car around 850/900 hp ), the best off most worlds , and has never exploded after 5 years Gazza's right on track, do you think nissan over looked their tailshaft design ( dia v's length ) There's a lot off after market ideas, but it's better that you match your need to their target market, ( track,stirp,road) 20 year old drive shafts will need some type off maintance, from a good grease to modifyed , ross
You have to do your homework first. I am very happy with my PST (precision shaft technologies) shaft, no vibration, fits properly and is very light. They have the correct 6 bolt flange so no adapter needed. ACPT shafts are another story, search on skylinesaustralia.com and you will find all sorts of problems ranging from poor fitment to vibration to failure. Forum member romvg30dett had an ACPT shaft break. Others have returned them due to them needing an adapter to fit to a TT diff. The ACPT shafts use a 4 bolt flange with a machined adapter to suit the 6 bolt TT diff. So yeah like anything there are good and bad c/f diffs out there and you have to do your homework before outlaying big $$
These are the ones I've seen many issues with. I don't like the idea of carbon driveshafts, but that's just me Bonding ally to carbon is always a bit hairy.
I can confirm this as well as I have half a dozen very dead m8's whos tailshaft dropped and pogosticked the panelvan they were all yahooing in many years ago............... L8r E
hey guys. Any advice as to where to get an alloy or steel single piece driver shaft made up in brisbane? and approx cost. Cheers
Just something else worth considering, the new zeds come standard with a composite carbon fibre shaft, which is actually a steel shaft with CF woven over the top. The reason they have the steel shaft is for protection of the occupants in case of a severe front end crash. The steel shaft helps absorb some of the crash forces and helps stop the engine from travelling through the firewall.
All the talk of two piece being stronger etc is not backed up with actual facts, there are other reasons for using two piece shafts & I'm willing to bet Nissans design guys were more worried about harmonics & noise etc than strength. Sure you may say you may need a larger dia tube to have equal strength (a bunch of BS for such a short shaft) but you will loose the mass of the extra uni joint, the joint consisting of an inner & outer spline, the flange for the uni joint etc = way more mass than a slightly larger tube. I don't recall seeing a steel tube in the 350Z carbon fibre shaft I had in my hands that had been cut to shorten it?? where did that rumour come from? or is the 370z that has that? why not the 350z then? Drive shaft loops are compulsory here in NZ if you increase the HP or change the shaft etc (anything that requires a cert for powerplant/drivetrain) BUT with a Z32 with twin exhs it's not really an issue as the shaft would just rattle around in the tunnel - for a bit until something lets go.....
The facts are'nt that simple to explain. If you want to understand why a two piece is stronger you'll have to do as I did and study the subject. Having studied shaft design as an engineering student I have a decent understanding of the subject. This came from a video the nissan engineers did about the build of the 350Z for the US. Maybe the american ones are different. The link I have to the vid doesnt work anymore so its a bit hard to prove. Either way it doesnt discount the safety aspect of a steel driveshaft over a carbon fibre one in regards to a heavy front end collision.
