Towing Capacity vs. Suspension Capacity: What’s the Main Difference?

Understanding the connection between towing capacity and suspension capacity is important for any RV or truck owner. It will determine more than the weight you can pull, including how your vehicle handles the load. Let’s review towing and suspension capacity, and how to get the best RV suspension upgrades. 

What is towing capacity?

Towing capacity is the maximum allowable weight a vehicle can tow, as determined by the manufacturer. Exceeding this limit can lead to dangerous situations like trailer sway, brake wear, and difficulty stopping. To determine your vehicle's towing capacity, consult your owner's manual or check the driver-side door jamb for information. Remember, it's crucial to adhere to the manufacturer's recommendations to ensure your safety and the longevity of your vehicle.

What is suspension capacity?

Suspension capacity, also known as payload capacity, refers to the maximum weight your vehicle can carry, including passengers, cargo, and tongue weight from a trailer. This weight directly affects your vehicle's handling, braking, and overall safety. To calculate your suspension capacity, subtract your truck's curb weight (the weight of the empty vehicle) from its Gross Vehicle Weight Rating (GVWR). Exceeding this limit can lead to suspension damage, poor handling, and even accidents.

How do you know if you need a suspension upgrade?

While not everyone needs a suspension upgrade, it's essential to be aware of the signs that your vehicle might need some extra support. If you notice the front end of your vehicle dipping lower than the rear while towing, excessive leaning on turns, or a sagging rear end, these could be indicators that your suspension is struggling. Additionally, bottoming out on bumps, difficulty steering at speed, and trouble braking while towing are all red flags. Remember, a suspension upgrade is not just about comfort; it's about safety and control.

Which suspension upgrades are best for you?

The best suspension upgrade for you will depend on your specific needs and usage. There are many different options available, such as helper springs, active suspension systems, and sway bars. Helper springs provide additional support to your existing suspension, while active suspension systems offer load leveling capabilities. Sway bars can help reduce body roll and improve stability while towing. Consulting with a professional at Mainline RV & Truck Service can help you determine the most suitable suspension upgrade for your vehicle and driving habits.

Sway Control for Maintaining Stability While Towing

Trailer sway is dangerous and can occur when towing, especially in windy conditions or when passing large vehicles. It can quickly escalate and lead to loss of control, making sway control a crucial aspect of safe towing. Sway control systems use friction or other mechanisms to dampen the side-to-side movement of the trailer, helping to maintain stability and prevent sway. Consider investing in a sway control hitch or other sway control devices, especially if you frequently tow in challenging conditions. Your safety and peace of mind are worth the investment.

Upgrading Your Brakes for Stopping Power

When towing, the added weight of the trailer puts additional stress on your vehicle's braking system. This can lead to increased stopping distances and reduced braking performance, potentially compromising your safety. Upgrading your brakes to a more robust system can significantly improve your stopping power and enhance your control while towing. 

The Importance of Pr§oper Weight Distribution

When the weight of your trailer is not evenly distributed across its axles and your vehicle's hitch, it can lead to trailer sway, uneven tire wear, and reduced control. To ensure proper weight distribution, use a weight-distribution hitch, which helps to transfer some of the trailer's tongue weight onto the front axle of the tow vehicle. This improves stability, braking, and overall handling, making your towing experience safer and more enjoyable.

Tire Pressure and Towing

Under-inflated tires can increase rolling resistance, leading to reduced fuel efficiency, increased tire wear, and even blowouts. Over-inflated tires can reduce traction and make your vehicle more susceptible to hydroplaning. Always check your tire pressure before towing and ensure that it's set to the manufacturer's recommended levels for both your tow vehicle and trailer. Remember, maintaining proper tire pressure is essential for safety and can help extend the life of your tires.



Regular Maintenance is Key

components andhecking and adjusting tire pressure, inspecting and lubricating suspension components, and replacing worn or damaged parts as needed. By staying on top of maintenance, you can prevent premature wear and tear, ensure optimal performance, and avoid costly repairs down the road. Remember, a well-maintained suspension system is essential for a safe and comfortable towing experience.
