Is there anyway to increase the Max Tow rating of a truck ??? Like increasing the cooling capacity of the Transmission, Airbags under rear suspension plus sway bar etc .......
Thanks
Yes, there are ways to increase the max tow
capability of a truck, not the "rating". Ratings are only given by a guarantor, and if you upgrade the truck yourself there is no guarantee on the capability, so no "rating" change.
You also don't specify how much of a change so the answer has to be "yes". Changing out the rear end ring gear and pinion will increase the amount you can pull, however in order to minimize sway, you need to increase payload also. If you have a 1/2 ton truck you are payload limited so the increase might not be as large. Adding air bags, cooling and what not is all well and good, but then you have to consider heavy duty axles, brakes and frame. Chances that would make the decision unfeasible.
Depending on the desired change simply getting a heavy duty truck with the appropriate ratings would probably be more cost effective, especially if bought used.
