This guy left a phone number on the auction site. These are about 1.5 hrs away from me. If all three are good and I can find two people who really are interested in them, I would go and look at them. Seems like the only downfall is only being able to use over or under gear in 2wd. Three of us could have these in our trucks for a fraction of gear vendors cost. This would be like the 5 on 3 setups Mack used to use I guess. Under drive for heavy towing, 1:1 for around town, and od for highway. Even seems more useful than GV. Any idea how much drag they create in the driveline? Some of that big truck stuff takes power just to turn the big, heavy gears inside. If anybody is interested, message me.
That is a single countershaft gearbox, the drag is minimal, the REAL heavy duty brownies ( 1241, 1241p )are twin countershaft and those would have prohibitive parisitic loss. I think the weight of my driveshafts puts more drag on than the box, my driveshaft builder was worried I had some monster powerhouse modern diesel and was going to be taking it to the pulls or something, because he built shafts stout enough for a semi
Shifting behind my zf5 goes as follows, when REAL heavy or towing out of a bad place, UD, 1, 2, 3, 4, 5, DIR-2, OD-2, DIR-3 , OD-3, DIR-4, OD-4
DIR-5, OD-5
This is all the direct progression, rarely are that many splits needed, even when towing, I normally leave it in OD and tow on the highway in 4over, it's the best for fuel mileage and power with my 4.10 rear, then split upper geaars as needed in the mountains
