I was thinking more along the lines of the ring and pinion being uprated rather than the locking assembly itself, not sure I'd trust an oem unit for too long, that was all.

mine has been in for about a year and not had any probs we had a spare diff laying about so we thought we would weld it and test it to see what would happen to it
how long it would last , and how much of a job it was to do and live with day to day and tbh its been fine so we are just running locked diffs to see if anythin brakes

and two way difs give up and end up like a lsd then you haver to have them recond so welded difs are far better

I'd rather fit a spool than weld one up but each to their own n that.

whats a spool ??

standard diffs are that cheap now it seems mad not to have both lol

A spool's a mechanical device to lock up the diff rather than welding it up. 99% of drag cars use them, and they're quite popular with drifters across the pond.

mmmm that sounds a good idea ive not heard of them before that maybe worth looking into

a spool isnt a mechanical device to lock up the diff

its just a gear - the centre is solid

The larger section bolts to the ring gear and the shafts slide in each side. I'm pretty sure either Mark Williams or Strange Engineering will do a Skyline one....worth a search I s'pose.

It's not a gear at all....it bolts to the existing ring gear....making it a mechanical device.

well the research i dug up was a gear with a solid centre ie spool

so we are both right, or cant you take that?

and ok

its not a mechanical device to lock up the diff, it is a solid gear (where available )

Can't I take it? What? If you want to get in to a piss-fest be my guest.

No it's not a gear with a solid centre at all, it's a completely seperate unit independant of the ring and pinion (like the picture above!!!). The spool unit itself is retro-fitted to the existing ring gear and lets both half-shafts slide in to a common spline which "locks" the diff.

So no, it's not a solid gear, and yes it's a seperate device (or component if we're being a pedant about it). Yeah, by fitting one the diff unit becomes a solid unit, but the part itself is additional to the gear assembly.

I fitted one about a month ago, as I have done regularly for the past 9 years.

its not an assembly, its a part that fits into an assembly

Erm...........

That's what I've already said??

yawn

anyway happy, this spool looks very simple.

if anyone has a liner or above mentioned diffs that are the same as the liner, give it to jody or me and one of us will model a spool up and could get them made. i can get them made from EN36 and have them tufftrided but i doubt it will be cheap by any means.

anyhow, just hand one over and im sure we can work something out
