A few of the Top Rockcrawlers in the states are running Rockcrusher Diffs with great success!

What sort of Axles and Unis do you get with it for $8100.00???

And if you don't mind me asking what is it going in????

G & J gears got some diffs made (nissan 4.6) from Italy and some were rather BAD, but I believe the rockcrushers are made here by ?? for them and sold to the USA. as well as us in Oz. Niot sure though. They are definately the same company.
80 series, Locked both ends, Q78ed & a massive 57 k/w to boot!!!!

There appears to be some issues raised on Pirate and I've had another person provide me with some first and second hand experiences with them.

A front HP with 35 spline shafts, 1480 unis, ARB and 4.88 gears – A good price but I’m keen to find out more about the stories I have heard. Like anyone, I don’t want to be stuffed around otherwise I’ll look/go elsewhere.

G & J Gears now call themselves Rockcrusher Diffs.

I don't think they manufacture the hypoid ring and pinion gears, there are few manufactures of hypoid gears around the world.

The rockcrusher high pinion 60 housings, Cs, knuckles hubs, steering arms and rear axles are manufactured in Australia. These are well designed, very strong and cost less than comparable items in the USA, which is their main market. The high pinion ring and pinions are the same as used in the front of Ford F350s. They use Chevy brakes. Wheel stud patterns can be 6 0n 5-1/2" (same as toyota) or common US 8 stud pattern.

They do not make front inner or outer axles, but may in the future. They appear to have problems getting front inner axles from the USA.

There have been some rear Rockcrusher diffs built here, but so far no fronts completed AFAIK.

I have no affiliation with Rockcrusher. If you are serious are getting Rockcrusher diffs, then PM me.
