Was an unlimited mile warranty available on the Kodiak's when they were being built?

HI Hank,

The Pbrake is a drum type and it will not allow ANY movement in gear. Its the big drum at the diff yoke.

Torque and HP are derated for longevity under commercial operator conditions. I had a 2019 3500HD flatbed and didn't really notice much difference except the 4500 gets things moving alot quicker the the 3500 did-- probably due to trans gearing and the 4:30 gear set.
My mileage got better as it broke in and now averages 9.5-11.5 pulling 17-20K. I usually set my cruise @ 68-70. We don't have any big hills to pull down here but we found the truck will pull just about anything you can hook to it such as a trailer load of cattle @ 35K we had to deliver to buyer.
By now you probably found out that the truck has a governor set to 75MPH-- has to do with the tire speed rating I think.

Sambor, hankbambam

Thanks for all of the information in this thread. I was looking to set up exactly how you have it hankbambam, with the CM AL ER bed!!!

While I know that these trucks are meant to be loaded, I was wondering what type of fuel economy you are getting without a load or trailer?

Has anyone heard of a tuner planned for these trucks? I am more interested in a tuner to increase the maximum speed of 75 Mph.

Thanks in advance.

I get about 12 mpg on mine. Just rolled over to 10K.
Speed wise, the limiting factor is the rearend gears. 4:30 is what mine is and speed limiter is set to that. Tires are another item you need to look at for their speed rating.
If you go to GM Techlink the current issue has a chart explaining the speed ratings for the different gear rations available.
As for any tunes -- engine is basically a L5P. With different ecm programming and a smaller turbo to make boost quicker for more low end torque.
I don't have any problems getting my trailers moving fully loaded. My truck weighs 11082 with full fuel and tools. Yours should be a little bit less if you get the alum. bed and same wheelbase.
Holler if I can help you with anything.

^^Extremely important on this type of equipment.^^

As as example, the 19.5" tires on my truck are only rated to 80 MPH.

Be careful.

I think the goodyears on my truck show 72 or so on the sidewalls but their website shows that the rating was increased to 80. they are 19.5's as well, wheels are Alcoas and rated for 4500 each.

to change the speed limiting on the truck would require either the dealer reset it or a new programming. Not sure the dealer would do it depending on what gear you have in your truck and you want to exceed that rating.

Which truck did you get? Post a little info on it please.

I am still in the research phase. There was so little information a year ago that I elected to wait.
