Scaled my duramax last night.

I don't think in any of the 15 or so trucks I have owned from Ford, Toyota, GM, Nissan, and Dodge have had the sum of the axle ratings equal the GVWR.

This gives flexibility in loading.

How does your 2500 do with a plow? Any major tire wear? Around here none of the dealers will sell a plow for them without a front end upgraded kit like Meyer offers. The 4,400# limit has been a factor. This has been a reason you see many more plows on stait front axle trucks with higher axle ratings.

That makes sense about the GAW ratings. I have yet to actualy plow any snow yet with my DMax. I installed the plow this fall, but it has not snowed enough to accumulate here yet. Im not complaining though !!!! I have hooked the plow up and driven down the road, and it did fine, The front sagged 1/2 to 3/4 of an inch when i raised the plow, but the back came up 2 inches. 700 lbs in the bed seems to stop all of the back end rise when lifting the plow. We have a few reg cab 2500HD trucks at work with plows, a 2005 and 2 2006s Two have western straight blade ultra mounts, and the other has a Meyer EZ classic 8ft poly professional straight blade. My truck as well as the DOT units all have the GL torsion bars from the factory which yields a 4800 lb front GAWR. All trucks have had the T bars turned up to level, and the work trucks sag a little over an inch with the bigger plows on them. We have had really good luck with our 2500HD s mechanicaly We normaly get well over 100k before the first front end over haul, tire wear has not been an issue, and they plow great. These trucks are used by supervisors during winter road snow removal operations, so they are not getting crashed into snow piles in parking lots constantly, they are plowing freeway turn arounds, Our outpost and head quarters, cleaning up intersections, freeway ramp tails and burms etc. They will drop the plow and go for 12 hrs, literaly. The biggest issue We have had with the 2500 s is rust in the rocker panels, cab corners, hood, and brake and fuel lines. The Magnesium transfer cases also corrode away badly around all the case bolts till all the oil leaks out. All 3 work trucks have had t cases replaced due to corrosion, min is still nice, but I give it special attention since I know it to be a problem area.

Trucks never have GAWR close to the true capacity of the axle. The AAM axle in that DMax truck has a true rear axle capacity of 10k or so.

are they still using the "14 bolt" rearend? I once had a '76 gmc with 8600 gvwr that had a 14 bolt rear end and a dana 44 up front- seemed like an odd combination :confused3:

 

[Peacock]

Yes. It's made by AAM now. Same basic rear axle. His truck has the 11.5" rear axle. The 14 bolt semi floater is 9.5" and the full floater is 10.5".

The old 14 bolt FF is in the gas HD trucks and has been since the re-design in 2000.

Thanks for links Ryan. Typically I've run my tires to the max pressure in order to get the best gas mileage and for load carrying. But its not the best for tire life.

It's been revised a bit. I believe the carrier is a different design. AAM produces it now for GM.

I have seen lots of 2500HD's with a AAM full floaters and gas engines. Usualy the gassers dont have a harmonic balancer on the pinion where the AAM in the diesels always seem to.
