I have heard nothing but good feedback on the Aussie Lockers and they cost 1/2 the price of a Detroit. I had the front of my 86 (IFS) Turbo 4Runner locked with a Detroit EZ locker never had any trouble with it and only broke 1 half-shaft over the 5 years I owned it. Both of my brothers had their IFS fronts locked too, a V-6 91 extra-cab and a 87 Turbo 4Runner. The only point either one started having issues with the IFS is the one with the 87 Turbo 4Runner had the Downey shafts and he couldn't keep them on the truck. He broke those cheap
shafts almost every other run. Of course the 4Runner's were autos but the V6 Extra Cab had a 5 speed and had no issues at all with the shafts or 3rd.
