Tow Capacity Is it a combination of the frame, engine, brakes, suspension, etc?
Hello all - I'm curious as to what determines a vehicles tow capacity? There's obviously a big focus on towing capacity on a lot of new vehicles now, so I'm just wondering how a vehicle's tow capacity is figured.
Is it a combination of the frame, engine, brakes, suspension, etc?
It's a little strange how a Chevy Silverado truck, for example, can increase it's tow capacity by 2K lbs or so, from one year to the next with seemingly very little changes from one year to the next. Or, why can Ford's F-150 tow more than a dodge with a bigger engine that has more torque and more HP?
Here is an example, ford f250 with an 3.55 rear end has a gcwr of 16000 lbs yet the exact same truck with a rear end of 4.10 is 20000.
Your rating is based on engine, transmission, rear axle, and vehicle frame. Not sure if that helps you any but I hope it does.
And it will be the least of those many things that determines the actual weight rating. Unfortunately, the engineers won't tell you which one it is. In the case of an motor coach, it's often the tires.
