I have yet to hear or anyone blowing up a diff in these. I run mine on a 4s Neu 1509 1.5Y and the diffs are smooth as butter. I'd really like to get some of those CNC hubs and carriers, if they'd show up somewhere for a reasonable price I'd jump on them.
Those Ti links look great for the rear as well
, I have some Lunford Ti turn buckles coming in the mail for my front end, can't wait for them to get here
