specking a new truck

[Brock]

I don't do dump trucks but if I did I would spec 4:30 on 11r24.5. Better for stop and go traffic and getting out of mud plus when you are up to speed,you'll be running 1600 rpm getting the emissions warmer. Goodyear g741msd tires. Primax suspension. I would drop the 485 down to about 450, no xhance of snapping the driveline if stuck in the mud, engine will produce less emissions and would have a easier life due to the gearing.

I don't know if you pull a wagon or not. I'm also not sure of your operation so take my thoughts with a grain of salt.
