Hey guys, i have a UC Torana with a Salisbury Diff at the moment. I will be converting the car from a 6cyl to an 8cyl and want to know what diff will be the best to run in it. The car will be used mainly for cruising on the roads but i will want to take it to the drags every now and then. I want to have a tru-track or LSD in it and have it with disc brakes.

Keen to here the advice, thanks

the best and easier way to go would be a 9in as it will be lot easier to work with when changing ratios and choices of axles etc...especially if you plan on doing some drag racing....over the years i've personally tried them all 10 bolt salisbury's as used the A9X's,..borg warner 28 spline,..9in diffs i'm currently running a GM 12 bolt in my car as i do a bit of drag racing as well...keep it simple and use a 9in as tru-traks centres a readily available and go the way of 31 spline axles if your running a manaul gearbox...

Yep, and depends how much power you're making, and how much traction you have. Sometimes it's cheaper just to do it once and do it right, especially when you start paying tow trucks to get you back home each time.

 

I used to bust 10-bolts on a regular basis back in my HQ days, although not quite as regularly as M21's! A Top Loader and a 9" were the goto options back then but these days there are so many more options.

all depends on HP you are going to run

 

Under 500HP go a Borg warner can get them for a few hundred Bucks they come in heaps of cars VN to VS VL non turbo 25spline But VL Turbo had 29 Spline also R31 skylines and Nissan Pintara but it has 25 Spline there will be heaps of ratios to be had as well

 

if you are going Big HP 9 inch or custom 9 inch from place like CRS
