Rear Sway Bars

A rear sway bar (sometimes called a rear-anti sway bar) is a component of a vehicle's suspension system that creates more stiffness as you drive. The stiffer your suspension is, the less roll you'll feel when you turn your car and the more stable your vehicle will be overall. Read on to learn more about what a rear sway bar is, what a rear sway bar does, and how it helps to increase your handling.


What Is a Rear Sway Bar?

sway bar location

A rear sway bar is a torsion spring that extends the full length of your back wheels. It can be either hollow or solid, with the solid versions used to improve the steering on heavier cars. Hollow ones are typically installed on cars, though some owners will swap out the hollow sway bars for heavier ones if they tend to drive quickly or stretch the cars to the limits.

When the vehicle starts to experience any type of twisting force, the sway bar will effectively prevent that force from destabilizing the vehicle. Rear sway bars work by connecting and leveling your two back wheels together so that they're unlikely to lift during a fast turn.

How Is a Rear Sway Bar Different from a Front Sway Bar?

Front sway bars stabilize the front tires, while back sway bars work to provide more rigidity to the rear tires. Cars do not generally come fitted with both rear and front sway bars, though drivers may choose to install an aftermarket sway control bar if they wish.

Installing sway bars is not difficult and is one of the quickest and most cost-effective ways to improve the performance of your car, truck or recreational vehicle. If you are replacing a stock sway bar with a larger diameter bar the install is quick. If you do not have an existing sway bar, the kits we sell will have everything needed for the install. The process will take a little longer than swapping out a stock one, but it is still something that can be done by most do-it-yourselfers. The amount of time to install will also vary with if it is a front or rear sway bar. The time required for installation is typically around 1-3 hours and will vary with your experience, tools and jacks. The install can be done in your garage or driveway with floor jacks and a pair of jack stands. Sway bars are designed specifically for your vehicle, which results in an excellent fitting product with reduced install time. After installing your sway bar, you will immediately notice a reduction in body roll and sway.

How to Select a Rear Sway Bar

Sway bars can either be purchased as an aftermarket product, or they can be custom made for your vehicle. You need to be careful that you choose a sway bar that isn't too stiff. The stiffer the suspension, the more likely you'll see some sort of lift in the inner back wheel. If you choose a rear sway bar that's too soft though, you also risk further steering imbalance. The level of over-stiffness can be tricky to determine when your car has a rear sway bar because the car will seemingly handle perfectly, right up to the point where it starts to spin out. Without knowing the bar's limits, drivers may feel anxious on the road about taking a curve too quickly.

To increase confidence, have a professional take a look at your suspension system to see what's what. If you already have a sway bar but it's not performing the way you want it to, you can find a different size or heavier bar to meet your driving needs. If you don't have a sway bar, then you can get recommendations on which one will both fit your car and give you the rigidity you need to handle the road.


When Should a Rear Sway Bar Be Used?

Rear sway bars are recommended for a variety of vehicles, though it's not always immediately clear when a rear bar is most called for. The general rule of thumb is that a rear wheel drive vehicle will benefit from a front sway bar, while a front-wheel drive will benefit from a rear sway bar. In a front wheel drive, rear sway bars keep the weight distribution across the tires as even as possible. The inside front wheels typically don't play a major role when it comes to steering your car, so you get the force exactly where you need it. So if you're coming into a curve too quickly and don't want to lean too far into it, a rear sway bar will ensure that you don't put yourself or your passengers in harm's way.

However, rear sway bars are recommended (whether you have front or rear wheel drive) if you're experiencing any type of understeering. So if you're trying to make a turn and the car only seems to want to go straight, you should look into getting an appropriate sized rear sway bar. The stiffness in the back will get your steering closer to neutral, so you have nothing but control over wherever you go.

Typically, you'll find sway bars in RVs, racing, off-roading, and heavy-duty trailing vehicles. Steering is of the utmost importance when it comes to taking corners, and there are a number of factors that can throw a driver off course. If you've ever gotten nervous approaching a twisting road after you've loaded up your truck, then it's easy to see why a rear sway bar should be used to keep everyone on the ground.

Why Use a Rear Sway Bar?

It's clear that sway bars are unquestionably helpful when it comes to improving your handling. The right one will give you the firm drive you need to handle even the toughest corners. If you have an RV, heavy-duty truck, or SUV that you don't intend to drive like a little old lady, then you should really test the difference of a vehicle with a rear anti-sway bar and one without.

Drivers are shocked at the improvement in their overall handling and control. One more reason to consider a sway bar is that it's a budget-friendly way to improve the lifespan of your vehicle. If you've noticed that your front-wheel drive car appears to be leaning too far into curves and you don't have the money to upgrade the full suspension system, this is truly a product you can't live without. Your tires and your engine will do far less of the work when you have this stabilizing force in your car. When you think about both the importance of your well being as well as the cost of maintenance, a rear sway bar may be worth its weight in gold.
