1) also looking at a new 2003 Dodge 3/4 ton 360 in town that had what had to have been about a dana 70 up front and a dana 80 in the rear.
2) Also isnt the dodge standard transmission the same one that used in Chevy, the NV 45oo?
3) As far as transfer cases goes I dont know what Dodge uses but I suspect that there isnt much difference between the one used with the Cummings and the one used for gas motors?
4) Anyway my point is that any set of Full Float axles with over 9"ring gear should be plenty for the cummings. If it isnt its because of how its being driven. Look at all the 400 plus Horse Power muscle cars that came stock with a dana 60 or even a Ford 9" rear end 30 or 40 years ago.
5) Also about front coils. Those trucks come from the factory with the front end to low on them. The dealer in town actually puts leveling coils on them before he sells them.
6)But even if it was a light duty truck what does a set of HD coils cost?
7) As far as the radiator im not sure. But there again whats the big deal about putting a bigger rad in front? The old one wouldnt have a lot of miles left in it anyways.
8) PCMs? What does this stand for?
1) In 2003, Dodge went a different route. Those are 10" Corporates up front, and 11's in the back. Bigger gearsets, but lighter duty than the Danas they replaced. Also, in 1999 - 2002, the LD designation was removed from the gas engined trucks, so the diffs would have been the same gas to diesel. 1994 - 1998 was a goofy bunch of years with multiple transfer cases and different axles all over the place.
2) In 1998 the NV4500 was the standard transmission, but it wasn't the same as the Chevy NV4500. Dodge gas engines (except v10 and 1/2 ton) and all Chevs got the LD trans.
3) Big difference between the NV231 (1/2 tons), NV 241LD (gas engined 3/4 tons) and NV241HD (v10, diesel) by the tune of 100 ftlb torque handling (or more).
4) Its not horsepower that kills, but torque. 400 HP muscle cars were often saddled with less than 350 lb/ft of torque. Diesels, especially Cummins, are torque monsters. From 1994, you couldn't get less than 450 lb/ft, and much of that was at low RPM. You stuff a 9" Ford rear diff on a Cummins, you'll tear in half the first time you tuck under a trailer. Even the old 6.9 and 7.3 diesels needed 10.5" Ford diffs to stay glued together.
5) Actually, he'll put levelling blocks under them. 2" blocks stuffed inside the coil towers.
6) The last set of HD coils I sold were 500 bucks.
7) Hmmmmmm, from 1995 on, they should have been the same rad. In 04, they split apart again.
8) Powertrain control module. Its the gizmo that receives engine readout information from the ECM (Engine Control Module) to run gauges, shift the automatic, etc etc etc. Without a PCM/ECM match, there would be no gauges, no power to the starter, no turn signals, etc etc.
Pre-1994 gas to diesel swaps were very simple to do. Yank the gasser, dump in a diesel, new coils, and hit the key. After 1994 it was MUCH cheaper to sell the gas truck and simply buy a diesel.
