yea 120y borgwarner diffs are pritty tough for there size. Especially locked mines not given me any grief thus far even when i had axle tramp problems. I never limiter dump it, say 3g max. My open wheeler died in 1 night but that was from spooling 2nd all the way up the road at least 20 times killing spiders! Id wager a bet they are very similar strength to h165. I have plenty of diff pics in my album too
