How to Increase Towing Capacity Effectively

A vehicle’s towing capacity makes transporting your boat, utility trailer, or pop-up camper possible. While Vehicle Towing Calculators are available to generate rough estimates of how much your vehicle can tow, these numbers aren’t necessarily static. You have the power to increase your vehicle’s towing capacity.

With the right steps, increasing towing capacity will ensure your towing vehicle can tackle heavier loads—without sacrificing safety and precision. 

For more information on how to increase towing capacity, calculate your vehicle’s towing capacity, and safely tow a vehicle (without mishap), read on.

Key Takeaways

  • Upgrading performance, safety, and stability features can supercharge your vehicle’s towing capacity.
  • Regular inspections and maintenance of your vehicle and equipment will ensure your towing vehicle is in optimal condition, reducing the overall risk associated with towing heavy loads.

What Is Vehicle Towing Capacity?

The term “towing capacity” refers to the maximum weight your vehicle can tow, including the weight of the trailer and its cargo. 

Understanding your vehicle’s max towing capacity is key to secure and efficient towing. 

For safety purposes, don’t tow vehicles or objects that exceed 75%-80% of the maximum suggested capacity. 

Factors that can influence your truck’s towing capacity include the type of hitch, the ball mount being used, the weather conditions, and the condition of your tires.

How To Calculate Maximum Towing Capacity

To calculate your vehicle’s maximum towing capacity, refer to the owner’s manual for specific details set by the manufacturer. The two things you will need are: 

  • Gross Vehicle Weight Rating (GVWR)
  • Gross Combined Weight Rating (GCWR)

Once you have these numbers, you can subtract the curb weight (vehicle weight without passenger or cargo) from the GVWR to calculate the available payload capacity. Then, verify tongue weight and hitch capacity to ensure they can accommodate the load. 

Speaking to an automotive professional can help you determine this number with ease. 

Typical Trailer Weights

For a better understanding of average trailer weights, from travel trailers to fifth-wheel trailers, check out the table below.

Trailer TypeAverage Weight
Small Utility Trailer500 – 1,500 lbs
Pop-Up Camper1,300 – 3,000 lbs
Teardrop Trailer800 – 2,000 lbs
Travel Trailer (20 ft)3,000 – 5,000 lbs
Fifth Wheel Trailer10,000 – 15,000 lbs
Boat Trailer (18 ft)2,000 – 3,500 lbs
Enclosed Cargo Trailer2,500 – 6,000 lbs
Flatbed Trailer1,500 – 3,500 lbs

Factors Influencing Towing Capacity

Several factors can affect your vehicle’s towing capacity, including the vehicle design, the vehicle size, the total curb weight, and any upgrades installed on your towing vehicle. To ensure you stay within safe limits, it’s important to calculate towing capacity before attempting to tow anything, especially when increasing towing capacity is a consideration. 

Engine Power and Torque

A vehicle’s towing capacity is largely determined by its engine power and torque. 

Larger engines usually generate more torque, which leads to improved performance and, therefore, an increased capacity for towing heavy trailers. 

To increase towing capacity, consider upgrading to a performance chip or a turbocharger, as these modifications could potentially enhance engine power and torque, thus improving your vehicle’s towing capacity.

Suspension System

A vehicle’s towing capacity can be significantly affected by its suspension system. Upgrading your suspension ca benefit your towing vehicle in the following ways:

  • Help maintain stability
  • Cushion the strain from the extra weight
  • Enhance maneuverability while towing or hauling heavy loads
  • Improve your truck’s stability and handling
  • Minimize swaying
  • Better respond to road bumps

However, upgrading your suspension may require additional maintenance. Not to mention, suspension upgrade kits can reach over $7000.

Consider the pros and cons before investing in suspension upgrades, and consult a professional for guidance on the best suspension enhancements for your vehicle.

Braking System

Safe towing demands a robust braking system. Otherwise, your towing vehicle won’t be able to stop responsively, given the extra weight of the load. 

Upgrading brakes for towing, such as installing larger brake pads and rotors, can enable your truck to handle the additional stress.

Another essential upgrade is a trailer brake control system, which can relieve pressure on your vehicle’s brakes, facilitating prompt and safe stopping of the trailer. 

How To Increase Towing Capacity Effectively 

Although it’d be nice if you could increase towing capacity with the flip of a switch, it’s more complicated than that.

To increase towing capacity, you may have to upgrade your vehicle’s suspension and braking systems. In addition, you’ll need to invest in a trailer hitch designed to accommodate a heavier load. Heavy-duty or even commercial-grade truck and trailer hitches are recommended.

When considering performance upgrades of any kind, always consult your vehicle manufacturer or a professional mechanic to ensure compatibility and avoid voiding your vehicle’s warranty. 

Remember that the upgrades should be reversible if needed.

Performance Upgrades

Performance modifications like upgraded exhaust systems, air filters, and programmers can amplify the vehicle’s horsepower and torque, optimizing its towing capacity.

These performance upgrades don’t just improve your towing experience. For example, upgrading your exhaust system multiplies engine power but also improves fuel efficiency.

Safety Upgrades

Upgrading brake pads and rotors and installing a trailer brake control system are both steps toward ultimate towing safety. These upgrades help your truck manage the increased stress, friction, and heat that’s expected when towing particularly bulky loads.

Stability Upgrades

Suspension enhancements and weight distribution hitches can significantly improve your vehicle’s handling while towing a heavy load.

A weight distribution hitch uses tension on spring bars to spread the tongue weight across the tow vehicle. This helps level out the load and improves stability.

Selecting the Right Hitch for Your Load

You’ve consulted the manufacturer for your GVWR and GCWR. You’ve invested in the recommended performance upgrades. Now, it’s time to choose the right trailer hitch. Receiver hitches, 5th-wheel hitches, gooseneck hitches, pintle hitches, and weight distribution hitches are the five categories of trailer hitch types.

Selecting an appropriate hitch for your load is vital for safe and efficient towing. Hitches are rated according to their towing capacities, and investing in a high-quality hitch will provide you with long-term durability and a hassle-free towing experience.

Be mindful of the hitch’s maximum weight capacity before use, as you don’t want to carry loads that exceed this weight ceiling.

Proper Weight Distribution Techniques

Weight distribution hitches help with load leveling and enhance stability, making them an essential tool for towing heavy loads. These hitches shift a portion of the tongue weight to the front axle of the tow vehicle, improving handling and reducing sway.

Before purchasing a weight distribution hitch, consult the manufacturer’s guidelines or a professional mechanic to ensure its compatibility with both your trailer and your towing vehicle. 

Maintaining Your Vehicle for Optimal Towing Performance

Routine maintenance is vital for optimal towing performance of your vehicle.

If you’re routinely towing hefty trailers or recreational vehicles, you’ll need to inspect your trailer tires for proper pressure, tread depth, and any cuts or damages.

To prevent rusting or the deterioration of key parts, ensure your towing and hauling equipment remains in a clean and dry state, whether in active use or in storage.


Towing capacity can be increased, but it must be done safely. Doing some math, consulting with professionals, and following safety guidelines are all important steps.

Once your vehicle is ready to tow your boat, camper, or trailer, you’ll want a safe place to store these towables. Whether you’re in need of boat or RV storage, Neighbor is an all-encompassing peer-to-peer storage solution for storing your things safely and close to home.
