How much power will the 185's gears hold up to for pulling?

I would say the torque tube shaft is the weakest link and it will hold 1000 hp. MACK

That's what I thought but reading some people said the rear end wont hold up.

When you get to a certain level of HP, you are running road gear, which is direct drive. The standard 2-pinion differential needs to be "needled" on the pinion shaft gears and have bronze washers behind the side gears (from a WD45) when you get over 500 HP. I also believe in a bronze rub block behind the ring gear (like a semi-truck axle) to minimize spreading of the ring gear to pinion gear under load. With that being laid out there, it is all stock components 100% until you get to requiring gear speeds faster than road gear. 1200 HP at 6700 lbs with 24.5 x 32 tires happens all the time in my neighborhood without troubles (yet).

That's good to know. I was afraid of braking something, only thinking about going to 100 hp.

If you are actually going to put 100 HP thru it AND pull a 4-bottom moldboard plow, you'd better raise the oil level in the transmission (overfill) an inch or so. You also better have a dual wheel on the left side and fluid in the rear tires. The differential can be destroyed in short order on a moldboard plow with extra HP. When the left tire is out there scratching away for traction, the poor differential gears are going for a ride !!!

I only have 3 acres so no plowing here. Besides in Western Washington the only thing I can grow is rain clouds. My 185 has the head off and so far I need pistons, just haven't made up my mind on which way to go (stock or more power).
