- Locking FT4wd 5spd Manual, 4.111:1 diff w 1.59:1 low range & front OBX LSD ;)
G’day all,
I’ve been keen to get a rear air locker sorted for my L series subi. One way I had been looking at doing it was to fit an R180 diff and find a locker to fit the R180. ARB don’t make a locker according to their current air locker list… So I did some searching and found this mob: Jack McNamara Differential Specialists The link will take you directly to the page that describes the locker – it actually a vacuum locker but an air unit can be created instead.
I’ve emailed Jack and already had a reply. It’s do-able (YAY! Said I) BUT we’d need 500 ordered to make it happen
The cost of the unit according to Jack is $1000 per unit which I thought was reasonable.
Only real obstacle to this is the 500 units required
Thought I’d share anyway – or has anyone got $500,000 to blow on the purchase of the units 
I would like to get a list together of who would want one (or three) but doubt it would be worth the effort as the 500 units seem un-attainable unless the word can be put out there.
Cheers
Bennie
