Uprated drive shafts

[Got.boost]

Hi everyone

Just been thinking about uprated driveshafts and do anyone make some as there's so big powered starlets put there now that much just snap shafts lol

Any info will be great

[_shaun_]

theres an american company but they are like £1k+ james@cjperformance was looking into it tho

[Azz]

Company in the states called driveshaft shop, thin IIRC they were

1100 delivered.

You must be able.to get the standard ones hardened I would imagin

[Jack-CTR]

wrap the standards ones in tie wraps and tape

nothing is stronger than that combo

When I was offroading you could get diffs and shafts frozen in such away that the molecular structure was brought togeather making the setup upto 90% stronger than it was before but how much this costs I couldn't say

[Flaminsam]

Cryogenicly frozen I've heard of, do it a lot to gearsets. It case hardens the metal.

[james@cjperformance]

we are lookong in to them we have found a manufacturer

rer to make them so currently sorting the cad designs and assembly they they can be tested against standard items. the other thing we have looked in to is uprated c v joints as it is very rare for the shaft itself to fail the weakpoint is the joint

[Azz]

The company DRIVESHAFT SHOP supply them with custom hubs ect so its a full bolt in kit but the same size as standard

Has anyone ever ran the above kit?

Wonder wether it lives up to expectation?!

[Starbo Moorley]

S some have said its no the axtual drive shafts, tge cv joints are a weak spot but ghe biggest weak spot is the cv goinh in too the hub because its too small do idealy you want custom hubs with bigger wholes for bigger shafts, but if you fit that, that leaves the g/box as the weak point.

[Dean @RW-Developments]

The company above sponser 1 of the fastest civics in the world so there shafts are the bollox

Who was it who bought new shafts from toyota ? Sure someone on here did and they were pretty fucking dear !!

It would be awesome if you could get these done james, and even better if they were similarly priced to your new clutch kit haha.

[morgey]

I've had to machine my hubs out to fit bigger bearings so i could fit corolla stub axles to fit c.v's to fit. I do now have to run washers under the hub nut but thats no biggie imo

Problem is our hubs are quite small so you cant fit very big bearings and therefore limits the size of the stub axle in turn the size of the c.v joinr etc etc

Which is probably why the DSS offer a new hub with there kit.

Im sure someone was looking into billet alloy hubs, being the case these could be made to suit an up graded d/s setup on aplication but would make the cost rise as would new bearings and stub axles would be needed along with new shafts and c.v's

And driveshafts are'nt cheap to make i paid £223 for one shaft custom made 30mm short than a corolla gti shaft.

Just my 2p

lol, that could possibly be me mate! Bought 2 new shafts that totalled just over £1k haha

that was me we knocked in on the head for the time being due to r and d costs, with various testing and reports needed against the number of people wanting them the price would have been way to high for my liking

to be fair you dont really see that many shafts breaking, ive never seen the actual shaft snap or shear at all it has allways been the joints that fail, I think if a uprated joint was made for both hub and gearbox were made that would be the ticket would be keep the cost down from buying a complete shaft.

[mattyD]

Uprated inner CV's would be sweet, standard from toyota cost nearly 400 notes!

[daniel_g]

Yeah man that must have been you matty, remember seeing it and thinking that seems pretty fucking steep like lol.

[Bean]

are the uprated shafts really needed though?? the only person who had bother is spuddy and his car is making alot more power than most of the other higher powered starlets and it might not even have been the power that killed them more the suspension setup causing it to hop. animal gt just had stock shafts and his lasted fine.

[shorty]

As above. cv's seem to take the power ok its only the 400+lads that suffer and even then was only the drag lads. i think its the least of peopkes issues tbh.

[AdamB]

Problem comes when uprated cv joints are fitted, the strain is then ttransfered elsewhere. This could then end up twisting the shaft itself as the next weak point. Its obviously cheaper to replace a joint than a whole shaft, hence why components are designed this way.
