Boost Your Ride's Stability with Sway Bars


At Refined Performance besides designing and making performance parts, we want to pass along any knowledge we have about the parts you are looking at to upgrade your vehicle. When it comes to improving your vehicle's stability and handling, sway bars are an often-overlooked component. Most vehicles come equipped with sway bars from the factory, but upgrading them or adding aftermarket sway bars can significantly enhance your driving experience. In this blog post, we will delve into the world of sway bars, exploring what they are, how they work, and the benefits they offer.

What are Sway Bars?

Sway bars, also known as anti-roll bars or stabilizer bars, are metal bars that connect the left and right suspension components of a vehicle. They are typically made of steel or aluminum and are designed to resist the vehicle's body roll or sway during cornering or sudden maneuvers.

How do Sway Bars Work?

During cornering, weight transfers from one side of the vehicle to the other, causing the body to roll or sway. Sway bars counteract this movement by transferring some of the suspension forces from one side of the vehicle to the other. They achieve this by twisting or torsion.

Sway bars connect to the suspension components through bushings and end links. On each side, a sway bar is joined to the suspension via the end links while the central part of the bar connects to the chassis. As the vehicle enters a turn, the downward force acting on the outer wheel causes the sway bar to twist. This twisting action exerts an opposing force that reduces body roll and keeps the vehicle flatter through the turn.

Benefits of Sway Bars

  • Improved Stability: Sway bars greatly enhance your vehicle's stability during cornering. By reducing body roll, they help distribute the weight more evenly across all wheels, enhancing traction and reducing the risk of skidding or losing control.
  • Enhanced Handling: Sway bars also improve the responsiveness and handling of your vehicle. With reduced body roll, weight transfer between the wheels is better controlled, ensuring a more balanced and predictable driving experience. This translates to improved control and confidence while maneuvering tight corners or navigating challenging road conditions.
  • Minimized Understeer and Oversteer: Understeer occurs when the front of the vehicle loses traction and continues to "plow" straight ahead, while oversteer occurs when the rear of the vehicle loses traction and starts to slide out. Sway bars can help reduce both understeer and oversteer tendencies, ensuring more balanced handling characteristics.
  • Reduced Body Roll: Excessive body roll can cause discomfort for passengers, especially during rapid lane changes or evasive maneuvers. By minimizing body roll, sway bars provide a smoother and more stable ride, reducing passenger discomfort.
  • Increased Tire Life: With improved stability and reduced body roll, sway bars help to evenly distribute the forces acting on the tires during cornering. This can lead to more even tire wear, improving the overall lifespan of your tires.

Upgrading or Adding Aftermarket Sway Bars

If you're looking to enhance your vehicle's stability and handling further, you might consider upgrading or adding aftermarket sway bars. Aftermarket options are available for a wide range of vehicles and offer various stiffness levels to suit your driving preferences.

Before making any modifications, it's important to consider your vehicle's suspension setup, weight distribution, and driving style. Overstiffening or mismatching sway bars can negatively impact your vehicle's performance and ride comfort.

Consulting with a knowledgeable mechanic or suspension specialist can help determine the right sway bar upgrade for your specific vehicle, ensuring optimal results.


Sway bars play a vital role in improving the stability, handling, and overall driving experience of your vehicle. By reducing body roll and enhancing weight distribution, they provide greater control and confidence during cornering and sudden maneuvers. Whether you're carving up twisty roads or simply looking for a more comfortable and stable ride, sway bars are a valuable addition to consider. Upgrade or add aftermarket sway bars today, and elevate your driving experience to a whole new level.
