MFG Ratings what are the limiting factors
I know this post will not change the MFG rating no matter what is stated that is not the point. The point is that there are many after market products out there and in the end they do not change what the MFG sticks on the door. But why ?
So what is the true weak link in any rating. Which component or components provide the drawback.?
I suspect that it may be possible to add a component or components and that if the numbers were crunched taking the new component into consideration, that the rating may change.
Most tow Vehicles fall short in the carrying capacity rating. You can pull a great deal of weight but the cargo carrying capacity is met or exceeded long before the GCVW is close. I will list a couple of items that I can think of.
1. The tires that are put on many smaller P/u are P metric tires they make these cushy looking grocery getters ride more car like. So one limiting factor could be the tires and don't forget those 20" rims that they all have to have now. So with a stronger Rim and E rated tire what changes. Well nothing really because the Mfg rating does not change. Right.
2. Shocks
3. Springs
4. Axles
5. Trans cooler
6. engine in some cases
7. Cooling capacity
The whole suspension thing has so many after market components that you would think you could tow or carry about anything.
In the end it is about a truck that is engineered as a complete unit and the MFG does not list the limiting factors. In the case of the F150 with a max tow pkg., the rating of Carrying capacity goes up to around 2,000 lbl from about 1500 lbs with just the HD tow pkg. So what are the other factors of weight and tow ratings. One could become convinced that they can exceed the sticker ratings if the change components.
