Sway Bar FAQ - Common Questions Answered by GRIPTECH
What is a Sway Bar?
A sway bar, also known as an anti-roll bar or stabiliser bar, is a suspension component in vehicles that reduces body roll during cornering. It links the left and right sides of the suspension to help balance the vehicle, preventing excessive leaning in turns. By keeping the car more level, a sway bar improves stability, handling, and comfort, providing a safer and more controlled ride, especially in sharp turns or uneven road conditions.
What Does a Sway Bar Do?
A sway bar, also known as an anti-roll bar, is a critical component in a vehicle's suspension system that reduces body roll during cornering. It links the left and right sides of the suspension, providing resistance to the vehicle's tendency to lean or roll during turns. By distributing weight more evenly across an axle, a sway bar enhances stability, improves handling, and contributes to a safer, more controlled driving experience.
How Does a Sway Bar Work?
A sway bar, or anti-roll bar, links the left and right sides of a vehicle's suspension using a rigid bar made from spring steel. When the vehicle turns, the sway bar resists body roll, reducing weight transfer to the outside wheel. This action keeps the vehicle more level, minimises leaning, and helps maintain tyre contact with the road, enhancing stability and control during cornering.
What is the Difference Between a Stabiliser Bar and a Sway Bar?
There is no difference between a stabiliser bar and a sway bar; they are two names for the same component. Both terms refer to a part of a vehicle's suspension system designed to reduce body roll during turns, enhancing stability and handling. The terms are used interchangeably in the automotive industry, with "sway bar" being more common in North America and "stabiliser bar" more frequently used in other regions.

What’s the Difference Between a Sway Bar and a Strut Bar?
A sway bar reduces body roll during cornering by linking the left and right sides of a vehicle’s suspension. In contrast, a strut bar, also known as a strut tower brace, connects the tops of the strut towers in the engine bay to reduce chassis flex during hard cornering. While both components improve handling, sway bars directly affect suspension movement, while strut bars provide additional chassis stiffness. For comprehensive handling upgrades
Which Sway Bar should I Change?
Upgrading either the front or rear sway bar first depends on your vehicle's handling characteristics and your driving goals. Generally speaking however:
- Front Wheel Drive: Upgrade the rear bar first.
- Rear Wheel Drive: Ugrade the front bar first.
- All Wheel Drive: Upgrade the rear bar first.
Upgrading the rear sway bar is recommended for FWD and AWD vehicles to reduce understeer and improve turn-in response. For rear-wheel-drive vehicles, upgrading the front sway bar can help reduce oversteer and improve stability. A balanced approach, upgrading both sway bars, often provides the best overall handling improvement. The GRIPTECH team can assist you to make the right selection for your car and driving style.
What Does 2 or 3 Points Adjustable Mean?
"2/3 points adjustable" refers to a sway bar design that offers different mounting positions on each side of the sway bar, allowing for adjustable stiffness settings. By changing the position of the end link attachment, drivers can increase or decrease the sway bar's resistance to body roll. This adjustability lets you fine-tune your vehicle's handling characteristics based on driving conditions or personal preference. Adjustable sway bars, like those offered by GRIPTECH, provides versatility for street, track, or off-road use, enabling you to optimise performance for comfort, stability, or aggressive driving
How Do the Different Mounting Points Affect Stiffness?
The different mounting points on an adjustable sway bar affect its stiffness by changing the leverage applied to the bar. Moving the end link attachment closer to the pivot point of the sway bar increases stiffness, as it reduces the lever arm length, making the bar more resistant to bending and body roll. Conversely, attaching the end link further from the pivot point decreases stiffness, allowing for more flex and a softer feel. By adjusting the mounting points, you can fine-tune your vehicle's handling to suit various driving conditions, such as maximising grip on a race track or enhancing comfort for daily driving. GRIPTECH adjustable sway bars offer multiple mounting points for precise handling customization.
How Does a Custom Sway Bar Benefit an Engine Conversion?
A custom sway bar can significantly benefit an engine conversion by optimising the vehicle's handling dynamics to accommodate the new engine's weight and power characteristics.
