Was just wondering if there was a difference between the maroon belly 7000 differential and the black belly differential.  Looking to get one to stuff in a 185 rear.  Thanks!!

The RH bearing and cup are larger. Don't know if the RH bearing carrier could stand that much material being removed.  We've always run the stock 2-pinion with needles on the pin and in later years went to flat needle bearings behind the side gears for thrust. We run 6700 lbs in a gear 20% faster than road gear with 24.5 x 32's , twin turbos at 1200+ HP. I wouldn't think about a 4-pinion for what we have and you'll still have to needle the 4-pinion.

This tractor will be a 362cu in alky.  We run 7000lbs here.  I have no idea on what HP I will be running, but I would think it would be around 1000, give or take.  I appreciate the advice.  Might be just as far ahead needling the two pinion that is in it.  I had heard of people stuffing a four pinion in them, that's all.

Whichever way you go, be sure to mark your transmission dipstick to carry the oil level at least 1 inch higher than it is marked for. And use 821XL or equivalent oil.
