good thing i was online, never would have seen that otherwise

i shortened the housing myself and did the mounts, so that cost nothing
cost $110 to have the axle cut down and resplined
just an open centre at the moment, but will be running a ford LSD once i have the money to get one

HI NICK.... HOW MUCH DID YOU CUT OFF,
I HAVE THE SAME R31 DIFF ASWELL FOR MY 1200 UTE,
WHEN YOU HAD THE AXLE CUT DOWN DID THEY NEED THE CENTRE ASWELL

yeah i think i was just to lazy to find a 13...might do that so i know what i can put on there if one of my tyres dies

I put 13s on mine, just had to trim the caliper cooling fins by a couple of millimetres. This was with an alloy wheel, a steelie wouldnt fit without lots of work.

got a pic of r31 axle and h165 axle next to each other?

no, but have a pic next to a 145 axle
we can pretend its a 165 axle

i can get a pic of the 28 spline next to a h165 axle, just requires me pulling an axle out of the ute diff

the cut down axle looks better coz it doesnt go under sized.....but this will do

haha i can kinda see why the r31 axles would be stronger...

maybe if we just wrap the 145 axle in tape till its the same size, then it will save the hassle of cutting down a diff

as long as you use 100Mph tape she will hold up just fine

this is for drag/street? i can't imagine you'd want something like that weighing you down at the circuit or autox ...

well its almost cheaper to do this and get an LSD than it is to get a h165 LSD, so there's one bonus, and you dont have to worry about collecting diffs to replace broken parts. IMO these benifits outweigh the cost of the extra weight

this is a pic of my r31 axels

machine the disk down and run different calipers... or just get rid of the disks and go to drums

edit: come to think of it, if you get rid of the handbrake crap (run commodore rear calipers) then 13s should fit

Prob a silly question, but does the tailshaft mate straight up?

Also whats the outside measurements disk to disk

you would be surprised... different flange (need the BW flange on the tailshaft and to redrill 2 holes in the diff flange) but length of tailshaft is the same

width is 20mm wider than standard after i cut it down

Whats the the uncut measurements?
Did you only cut one side down?

un cut its 1452mm
cut down both sides, used short axle as the long one and got the long axle cut down 135mm

Thanks for the info
