Squat is Not Normal

Think it’s normal for the back of your truck, van or SUV to squat or sag while towing and hauling heavy loads? Think it’s just the reality you have to live with when you load the family and hook up the boat or RV? Think again.

Not only is your vehicle not designed to operate in this matter, it also poses several hazards, including:

Poor Braking and Steering

Front tires account for the majority of braking power and steering. When the weight of the vehicle is primarily on the rear tires, and not distributed to all four tires, braking and steering can become compromised.

Poor Headlight Aim

When the rear of the vehicle squats down, the front of the vehicle angles up, resulting in improper headlight aim. Even a slight degree of change can make a huge difference 500 feet down the road.

Rough Ride

Minor bumps and dips in the road are amplified when your vehicle is loaded – making your drive uncomfortable.

Trailer Sway

One strong burst of wind can make your whole vehicle or trailer sway. When over-corrected or ignored, it can trigger a chain reaction that may lead to a total loss of control.

Body Roll

Rounding corners and curves shifts the weight in your vehicle and trailer, causing excessive body roll.

Bottoming Out

As your trailer and vehicle shift from bumps in the road, the weight change can be so drastic that it causes your vehicle to bottom out.

My vehicle is rated for a payload and trailer like this. Why does it squat?

The truth is that factory suspension systems on most vehicles are static – using steel coils or leaf springs. A static suspension is tuned to perform best under specific conditions. For example, most half-ton pickup trucks are not towing or hauling heavy loads every single day, so truck manufacturers design the suspension to ride most comfortably when driving without a load. This doesn’t mean that the vehicle can’t handle towing or hauling, it simply means the suspension isn’t tuned to perform best under these conditions. However, you should never exceed your vehicle’s Gross Vehicle Weight Rating.

What can I do about squat?

There are several load-assisting products available on the market today. While most options effectively address squat for a loaded vehicle, they present the same core challenge as the factory suspension. They are static solutions that leave your vehicle’s suspension tuned for a single driving state: loaded. This results in a whole new set of complications, namely an uncomfortable ride whenever the vehicle is not carrying a heavy load.

Air springs (also called air bags) are the only load support products that offer adjustability. Adjustable air spring kits work with your existing suspension to level your vehicle to normal ride height, thus eliminating the hazards of squat and the inconvenience of a static suspension. Adjustable air suspension enables you to change the spring rate of your vehicle on-the-fly by simply inflating the air springs when towing or hauling and deflating when riding empty.

Air springs can be adjusted using an on-board air compressor system or by using the included Schrader valve (the same valve used for filling most tires)
