Do you mean like on a Peterbilt front axle?

If so, it's all about manuverability.

the set back will give you a better steering diameter, but lessen the ability to load the rear more. the set forward will allow you to stack more weight on the rear axles because there is more balast (sp) out front...least thats my way of thinkin.

At work we prefer the set back axle, more manuverable with 57' trailers. We can get our KW T-600's in were we can't get a Pete 379 or KW 900.Rick

ok I see now, set backs allow the tires to turn more. it's weird but I think my Mack R model has a pretty tight turning radius, a LOT tighter than my old Int'l 4900, both are set forward axles. I guess every truck is different. I know my Dad's 94 Autocar dump (was a tractor) has a terrible turing radius.

still I personally don't like the looks of most set back axle trucks, with their long noses, better for aerodynamics though. I like big square hoods!!

Yeah who needs manuverability when you look good!:poke: 90% of the dirt haulers around here are running 379s or 900s. They get into some pretty tight places with them too. I guess if they had set back axles they could go tighter but they don't and the fact that they have 379s shows that they must be making a few bucks at it anyway:p

Does anyone have any good pictures of the two set-ups they could post?

The 379 day cab I once drove could turn on the dime, almost as good as the Volvo. :Thumbup:

Thanks for the pics, the bottom one is a 379 I thought. That is the one I used to drive when I was hauling heavy equipment. Believe it or not, that truck had a good turning radius.

Jim, how can you tell them appart, 379-378s that is? I know the top on is a 378, and what is the differences between the 79 and 78 with that axle set up? Noticed the headlights in the brochure and they talked about the two axle options.

Thanks
Rick
