I hear they've done away with all 10. 5's for the cummins (auto and stick); but I hear some saying maybe the shaft housing is a thinner wall on the 3/4 tons which is part of the lower GVW (not just the overload springs).
On my 01 2500 5spd. I had the Dana 80 Hybrid (80 guts, but 70 housing I believe), and the full 80's were on the duals only. So, is this the case with the 2500's these days, or are they Exactly the same axle as the 3500 SRW's? . . (and I'm assuming that only the brake size is still different on the duallys like the dana's were).
One more thing (I got a bet with a friend), what about the front coils? Are they rated different on the 2500 and 3500's? Or, do they have to take some of the load to get to the higher total GVW? And, aren't the main rear spring packs (not the overloads) the same on both (width/thickness/number/load rating, etc. )? I said the ride is exactly the same on both the 2500 and 3500 assuming all this is true.
