Can GVWR be Adjusted on a Dump Truck in New York State?

Question:

I recently purchased a tandem dump truck at an auction, specifically a town plow truck with a typical setup of a short wheelbase and a short box with a hydraulic tank behind the cab. I am considering stretching the frame to accommodate a 17-foot box and adding a lift axle. Can the manufacturer's GVWR be adjusted or is it fixed for the life of the vehicle? The current GVW is 66,000 pounds. Additionally, I am curious about the regulations in New York state regarding divisible load permits and how they may override the manufacturer's GVWR based on axle configurations and the bridge formula. Any insights or advice on this matter would be greatly appreciated.

What amount of net weight were you looking to add?

When asked about the expected net weight gain, Truck Shop replied, stating they were hoping for around 80,000 pounds. Providing some context, the truck is a 2006 model without diesel exhaust fluid (DEF) system. Despite having 100,000 miles and experiencing an exhaust valve issue before being auctioned, the truck was well-maintained by a single driver and remains in excellent condition.

The legal gross weight for your vehicle is typically determined by the bridge formula and number of axles in most cases.

I am curious about whether manufacturers specify a maximum weight limit (GVW) that cannot be exceeded, or if they allow for modifications that may increase the GVW. Specifically, I am wondering if a truck needs to be re-evaluated for its Gross Vehicle Weight Rating (GVWR) by a certified entity after undergoing alterations to increase its capacity. I have been unable to find a used VHD bumper, which led me to consider purchasing three new pieces for $1500 - a price that seems high to me. The truck in question is equipped with a 435 D12 engine, a 10-speed transmission, and top-level interior features. Thank you.
