Boss is going to get me a new heavy spec truck. I'm usually grossing 160,000 lbs. I'd like to know what some specs you would have to have. Have some loads that are around 130,000 also. Then alot of lighter loads under 105,000 lbs

Current truck is a 2006 KW T800 with a 475 ISX, 13 sp (16 series), 3.55 rears, 235 wheelbase, 12k front, 40k rear with a dual tire lift axle. on 285/75/24.5 rubber.

I get some say in the specs, and want to do it right. Lots of cruising at 75mph.

I made changes in Red


You will also want to consider putting on wide flotation tires on the front if you are going to go heavier all the time.

Years ago, ran an old Int'l set-up similar but with a 13 spd. We didn't have the flotation tires on the front, but there were times we should have. Especially when the front started to push that 20K limit. We would run 108,800K hauling jet fuel and grain.

remember you have to keep it under 600 psi road pressure on the tires.
