I was just looking at 2006 F-150s, that was on fords site. They used to use the 9.75" one. According to the site they now use 10.25s.
Oops, yeah, you are right on the Titan.. :miff: me..
Yes, the 14 bolt 9.5" chevy has been under various 1/2 tons for years. Diesel 1/2 ton suburbans used them I think since the mid 90s.
All in all, just noticing how the parts are getting bigger these days. Breaks are getting big, too.
