I'm going with Aussie early next year. I ran a lockright in a ford 8.8 and when it broke the chain reaction took out the ring gear, carrier and diff cover. this was with a 300ci 6cyl with 33's. as well my dad had one in his front dana 44 on his 66 bronco. the guide pins wallowed out really bad and sheared off. So, the 2 times my family has run lockrights, both failed. now he uses ARB/detroit combo. I'm still poor so I'll try the aussies out
