I too am wondering about rear ends..............truck rears that is.
Can't argue with the toughness of a 9"...also can't put a blue oval part on my GM truck.

Currently have a rebuilt truck 12 bolt with new Eaton posi, 3.73 gears, and "bearing saver" bearings. Running street 275/60-15 BFG's on 8" wheel, but I want to go to a wider 29"-30" tire, preferably MT ET Street drag radials and 4.11 or maybe 4.56 gears. Have a line lock, but its not currently installed. My 6.0L LY6 should be making over 500hp at the crank and is running thru a "built?" 200-4r, and I may add some spray....or preferably a Vortech supercharger later.


That said.......what is the "better GM" choice for a rear end tuff 'enuff to get beat on at the track by a 500+hp motor and sticky tires, yet still be up for street duty for weekends, cruises, long tours, etc. I know I'll also have to do a bit more for my 200-4r (or replace it) for it to live long. As for a rear diff.....I've always thought I'd choose a Dana 60......but the 9.5" 14 bolt semi-floater in our TBSS has me thinking about one of those.
