Yeah that truck haul's some azzz and it weighs alot too!! More weight = more stress on the driveline.

Alot of good information here with several different kinds of combo's.

Magnum Blocks is now also a "Myth that is Busted"!!!

So it's kind of safe to say an A-body is likely able to get away with a good deal more than that if a big heavy dakota can do that....or even a POS Dakota for that matter. lol
