Top Tips for Increasing Towing Capacity

Towing capacity is the amount of weight a vehicle can tow. It’s important to give your vehicle the best chance of success when you are towing heavy loads, such as watercraft or campers. To do this, you’ll need a powerful engine with a high torque rating, an adjustable suspension system and an upgraded transmission. But it’s not just mechanical components that will help increase your towing capacity there are also many other factors that should be taken into account! Read on for more information about how to maximize your trucking potential when hauling large loads!


The type of engine is one factor in determining your maximum load carrying capability; diesel engines have higher limits than gasoline engines due their greater power output. Check your owner’s manual for details on your specific engine and what load it can safely tow.

Tire Pressure

Be sure to maintain the proper tire pressure. Under-inflated tires lower maximum load capacity, so be careful not to let these numbers dip too low! Proper tire inflation is especially important when driving long distances with a heavy load.

Size Matters

The size of your vehicle plays a huge role in the towing capacity as well! In fact, larger vehicles will have larger capacities, so if you can’t afford a new truck now, you might want to hold off until you can – otherwise, getting a car may be your only option.

Tow Hitch

The type of tow hitch is also a major factor in your towing capacity! Towing hitches come in class I, II and III; what you need depends on the weight of your load. Choose one that can handle at least 150% of the weight you’ll be towing in order to maximize your chances of success.


If you’ll be using your vehicle heavily in the future, you might want to upgrade its braking system. This way, if it fails when you’re hauling a load, the added stress won’t cause any problems! You can also get brake controllers for more accurate braking when towing.


A heavy duty suspension system can make all the difference! Some load carrying capacity is lost when a car goes over bumps and dips, since this causes some of its weight to shift around on its springs and shocks. You probably won’t be able to afford an air suspension system, but a heavy duty set of coil springs or airbags can help you maximize your towing capacity.

Wheel Spacers

If you have trouble fitting in small spaces when maneuvering with a load, consider investing in wheel spacers. These add space between the front and rear axles to give you more flexibility when you’re towing large loads.

Upgrade Your Transmission

If your transmission is not up to the task, there’s no reason why you should struggle when hauling a heavy load. The transmission is responsible for transferring power from your engine to the wheels; without it, you’ll stress your engine and make it work too hard. Upgrade your transmission if it can’t handle a heavy load, or else gets a model with a commercial towing San Jose.

Reduce Drag

If you’re using an older vehicle when hauling large loads, you might want to consider the aerodynamics of the vehicle in question. The more drag on your truck, the harder your engine will have to work; this is true even when you’re not moving! A new hood or bed cover can help reduce the drag on these components.


Towing capacity is an important factor that should not be ignored when considering the purchase of a new vehicle. You can increase your towing capacity by upgrading certain components, such as brakes and tires for example, but you’ll need other modifications depending on what type of load you plan to tow.
