I have heard rumours that there is a manufacturer producing Fused drive shafts, which allow vehicles with re-inforced axles a weak point which is easily repairable during competition and which will not destroy the gearbox instead, has anyone heard of anything similar?

From the way these were desribed they were in the drive shafts which would obviously be easier to fix and access, I believe they were very quick and easy to replace. I think the hub fuses would not work with the maxidrive shafts which I am running.

GKN Driveline in the UK were also producing a similar hub endcap I believe

Yeah,

You can find info on it if you search the Peterson's 4 wheel site. They did a write up on it a while back. Its a driveshaft with borrowed technology from big rigs that pops sheer pins and lets loose, idealy before something else breaks. There were ways to select what sheer load would take out the shaft. I remember them being expensive, and the pins costing around $100 when you dropped them.

However, if you are running maxi shafts you have zero chance of ever doing any damage to your gearbox. Those shafts will let loose way before the np205 even feels anything. Also, is it smart to add another even weaker point to the drivetrain? I say no. Fuses in systems like this never seem to work. I stuck with spicer 60 u-joints even though I have chromo shafts so that I would have a fuse, and I have never broken one, but I have broken a whole bunch of other stuff! :eek: Anyway, I would save your money and spend it on stronger axles, not weaker d-shafts.

Let the cv's be the weak link in the front & buy them cheap on ebay! The R&R is pretty fast & you have better access than a ds.

Keep your shitty stock axles in the rear & do the same thing in & out.

Or pony up & do the Toys.

Or really pony up & the sky is the limit.


Or don't pound the piss out of it. Thats not much fun!!

Cheers for the feedback guys, in the end something will break was just trying to think if there was a quick and dirty way to fix it then it might prevent missing the end of the competition, as there will always as Peter pointed out be that obstacle which just won't be beaten, and in turn pound's the piss out of me or the Tomcat.

KAM does one. Very overpriced though.

A few years ago in a issue of one of the Land rover mags there was a guy who made a score cut on his axles to create a weak point. He figured it's cheaper and easier to replace an axle than something else on down the driveline.

Your right not a bargain, but at least I have found somewhere that would do it if I decided to go down that route.

Thanks.

cant find any more detail on the web. I did have a published article a few years ago re the GKN system, but heres what I found
