Strut Bar vs. Sway Bar – Choose the Right Suspension

A sway bar is a great way to reduce body roll and improve handling. They connect the wheels together, but strut bars offer better improvement in understeering because they’re mounted on top of your struts which means that if anything happens with them, then all bets are off when it comes down to being repairable or not.

Installing both sway bars and strut bars is optimal for a better driving experience. But it may not always be possible to install them side-by-, which one should you get? The answer will depend on your individual needs. Anyway, keep reading below as we walk through the differences between these two important vehicle components.

What Is a Strut Bar?

The strut bar, also called a brace or tower links your suspension struts to strengthen the chassis. these were designed specifically with MacPherson strut-type systems in mind but now many different types of cars can benefit from using them too. The strut bar is a great solution for those who have experienced this issue. It helps to counteract the effects of suspension geometry change that can occur when going around corners or hitting bumps in high-speed situations, making your car much more predictable during tight turns.

What Is a Sway Bar?

Sway Bar suspension includes everything from tires and springs to shocks, steering system linkages bushings joints. A sway bar helps prevent body lean when turning as well as making sure that the ride handles smoothly so you can enjoy driving without worrying about crashing. The sway bar is an important safety device that keeps your car from rolling when cornering at high speeds on uphill or downhill grades.

Strut Bar vs. Sway Bar: Major Differences

Suspension System Connection

The biggest difference between both body bars is their connection points. The role of a sway bar is to connect two wheels and keep weight distribution between them. On the other hand, A strut bar connects with suspension towers which help in stiffening up your car as well as reducing any chassis flexing by transmitting more force through its connected components rather than just having one heavy point directly attached at each corner like what you would find on most cars today.

Body Roll Reduction

A sway bar is linked between both arms to reduce the weight transfer when cornering. A strut tower has concentrated force distribution, but it also links two struts for better body control in high-speed situations like accelerating or braking on an inclined road surface with little traction available from rubber compounds inside tires due to naturally occurring humidity levels, etc.


In racing, understeering means when your car doesn’t stay on track. It’s caused by too little steering which prevents you from keeping straight ahead and can be fixed with stiffer springs or shocks that give more grip to the road but also make it harder for turns without causing over-steer. Struts help reduce this problem since they’re connected directly to wheels – reducing Under Steerings big time! But bar-type suspension systems like sway bars still work better than anything whatsoever so keep these differences between them in mind before buying anything expensively new just yet.


Cornering is one of the most important aspects of any car. Not only does it help with balance, but also corner Watches can save your life. A sway bar affects how well you turn and carries weight depending on what kind there may be. While Strut bars add more stability at high speeds while lighter cars require no such additions due to their lightness.

Shelf life

Strut bars are usually very durable compared to sway bars. They can last up to 6-10 years before needing replacement, whereas a worn-out Sway Bar may need service or even replace the entire unit.


Whether you want to save money and space or have an easier installation, a sway bar is a way to go. It takes less time than installing strut bars in your car because there’s no need for extra room behind either side of it.

Pros and Cons of Strut Bar


  • Stiffer chassis
  • Reduced wear and tear
  • Under-Hood Bling
  • Longer shelf life


  • The off-road performance takes a hit
  • Makes no straight-line difference

Pros and Cons of Sway Bar


  • Better body roll reduction
  • High-speed cornering
  • Easy installation
  • Affordable


  • To much weight
  • Reducing traction


Are strut bars and sway bars the same?

Sway bars connect the two wheels that are not being weighted by diverging from them. On the other hand, strut bars attach to your car’s suspension towers and reduce its flexibility for a more rigid feel in turns or when going over rough terrain. A sway bar connects both ends of each side while keeping weight distribution even across all four tires with struts providing extra support where needed.

Are sway bars connected to struts?

The sway bar is an essential part of your car’s suspension that connects the outer ends to components such as control arms and struts. Connecting these two bars together via bushings keeps things smooth, while also preventing unwanted movement.

Does the sway bar affect ride quality?

Yes, the design of standard Anti-Sway bars means they negatively affect ride comfort because they limit how far you can move your seatback.

Final Words

You can’t go wrong with either one of these, but we are happy to give you the final push in whichever direction. We hope this comparison has given you enough information to make a decision on what type of bars are right for your car.

Sway bars improve performance and are easy to install. However, a strut bar increases rigidity for a better driving experience as well as it should be.

Installing both bars will provide the best experience. However, if money’s an issue, get a sway bar first and save yourself some grief down the line.
