The air ride on my 932a2 IS NOT as good off road. It doesnt articulate as far.... it rides better. A single axle setup would work as well if not better than a spring setup. but the stock leaf spring set up twists up like crazy. The air suspension picks the tires off the ground on uneven ground...

Ive used longer pitman arms to quicken the steering. It worked very well. On a straight axle Bump steer is caused by the height difference between the pitman arm and the steering knuckle. The further above the knuckle the pitman arm is ,the worse it will bump steer. The longer pitman arm made...

Thats a beautiful job. I like the road plows they are a bunch stronger than my western pro 10ft. I always was worried about my frame with the winch extensions so i beefed them up a bit. I always keep an eye out for cracks or twisting but after 9 years its been good.

Call pittsburgh diesel in pa. They are friendly and knowledgeable. Which turbo you use is important you want as much boost as possible to keep egt's down.

Nice truck ...if you like it now try turning a little fuel to it..8)

the best way is get the #'s off the drivers side front of the engine

NHC 250 Doesnt have piston coolers so if you push it too far (fuel wise) it will score a piston. 270,290,300,335,350 etc have oil squirters that spray cooling oil on the bottom of the piston. you can turbo a 250 but the compression, timing, fuel timing ,cam etc is all different. Cummins...

You might have to let the truck roll a little bit when your trying to get it into high, trans always in neutral. Make sure your shift linkage and pivot shaft are nice and free. Make sure there is no air to the piston on top of the t-case (shaft lock ). They can be cranky but they always shift...

with no power to the dump valve for the t-case shift shaft lock and full air pressure you cant shift the t-case

this too M939 transfer case air lines installed wrong

try this link M939 series transfer case low range / front axle engagement

14.00's look good ,ride better and you get more top end on the highway jmho:driver:

HEMTT wheels are almost twice as thick at the lug area. They have a little less off set (they dont have the little bubbled out area by the lugs you can see on the front 5 ton rims by the lugs) which means on the front they stick out a little more ,when spun the opposite way on the rear they are...

Check the check valves (especially the one right after the dryer before the first air tank). When they get rusty and stuck , the dryer does just what your describing.

I havent seen any m939 trucks with electric wipers. You would have to widen the whole setup as well as change the internal arm lenth. If the wipers dont park ALL the way up to the left they are directly in your field of vision(m35-m809 wipers go from 4 oclock to 8 oclock m939 wipers go from 4...

Funny all my 250's sound different. Some have more power than others. My latest M923 sounds like a popcorn machine and has as much power, even after a tune-up.

I finally got done swapping bodies ,mounting the plow and wiring everything. Came out good. Im pretty sure I jinxed the snow for this year.

Ive been driving mine just about every day. I know the wheelbase is only a foot shorter but it definitley makes it easier in a parking lot.
