10 Best Sway Bar Kits- Comprehensive Buyer’s Guide 2021

Best sway bars for upgrading your suspension

In-car suspension systems, there is one component that keeps your vehicle from rolling over when it undergoes a curve or a turn on the road. It is called the sway bar or a stabilizer bar. 

How does a sway bar work?

A sway bar is important for your vehicle because it returns it back firmly implanted to the ground during curves and turns on the road. Don’t you have the feeling sometimes that your car is in danger of toppling over especially when you are driving at a fast speed and then you suddenly negotiate curves and twists on the road? 

Be thankful that you have a sway bar connected to the car’s front wheels. It is U-shaped and is made from durable steel. What happens when your car turns is that its body rolls to one side. This means its weight shifts to the direction where it turns. 

At this moment, your car is in the process of a body roll or body sway. It is but fortunate that you have a sway bar that controls the suspension of each wheel which results in an even-out action of your car’s body roll. The sway bar makes your car stand straight on the road, after negotiating the turn or the curve. It avoids the car from being controlled by the road conditions. 

Will the rear sway bar help with towing?

Yes, a rear sway bar will help with towing a trailer, but absolutely zero swayings is not possible. There will still be instances when swaying happens because of crosswinds, drafts from passing trucks and vehicles, and incorrect braking techniques. 

A rear sway bar will help but when you pack the trailer you tow, put more weight in the front to reduce swaying. Also, drive slow when towing, not more than 55 mph. 

If the trailer that you are towing is more than 26 feet in length, it would be best to have two friction style rear sway bars.

What to consider when choosing Sway Bar Kits- Buying guide

Compatibility with your car

There’s nothing more annoying than discovering after you have purchased a sway bar, that it doesn’t fit your car model. Be sure to take your time to study the sway bar’s compatibility chart so that you will be sure it is a perfect fit. 

Made in the USA

There are sway bars that are manufactured in other countries, but the products that are fabricated in the US mainland are the best. There are multitudes of American car owners who would want to retain the vehicles that they have used for a couple of years.

And one way to maintain their cars in top condition is to replace car components like sway bars with quality US-made ones. 

Racing or motor home worthy quality

When a sway bar is deemed worthy of installation on race cars or on massive motor homes, they are deemed of superior quality because these cars demand unmistakable quality. But in the end, just make sure that the sway bar fits your vehicle. 

Made of solid steel

I would choose sway bars made of solid steel anytime, over ones with hollow tubes. The unpredictable conditions on the road demand a lot on your car and solid steel sway bars can withstand the pressure. 

Easy to to install DIY

Because of advanced technology, many sway bars have designs that can be easily installed by an amateur or a non-mechanic. Some don’t even require tools or minimal manual tools. But still, others require drilling which I don’t like. 

Warranty

If the company that manufactures a sway bar is confident with its quality, it would offer an extended warranty on the product, confident that whatever the customers dispatch on the sway bar in terms of cruel conditions on the road, it can withstand all these challenges. 

Some kits include end links too, so it means that the price you pay includes these end links. You might as well change the end links too. So, if this is important to you, buy a sway bar kit that includes end links, bushings, and other components. But if you did buy a sway bar without end links, you don’t need to buy new end links if they’re not yet worn out. 

When to replace the sway bar?

There will be obvious signs that you need to replace your sway bar. You will be experiencing a free play of more bouncing and instability when your car is negotiating curves and turns or when pushed up and down. 

The catastrophe that might happen if you delay the replacement of a worn-out or damaged sway bar is that it can separate while the vehicle is in motion. This could be life-threatening to the passengers. 

You will also feel that your car will lean excessively on its side when there are turns and curves. Don’t wait for trouble to happen and check out the sway bars above which can fit your car perfectly. 

Will sway bars make noise?

A bad or worn-out sway bar will definitely make annoying noises. It breaks and loosens up, it can make rattling and clunking sounds because it comes into friction with other parts of the suspension system. 

Will sway bars affect tire wear?

A worn-out sway bar will definitely make premature the life span of your tires because the grip of their rubber on the road will be inconsistent. It is always advised that vehicle height be maintained, and a good sway bar will accomplish this. But a replaceable sway bar will definitely wear out your tire thread faster. 

What I recommend Final Touch

The first thing I look for when buying a sway bar or any car component for that matter is whether it is made in the USA. That’s one check off the list. 

The next is if it is easy to install by myself because I am quite a car tinkerer and I enjoy this activity. It would help if it doesn’t require fancy tools to install, and worst would require drilling. If it’s a direct fit, all the dimensions will be perfect, and it would be a joy to install as if you’re just playing with Lego blocks. 

The next is it should be made of exquisitely superior material, and in this case, for sway bars, it should be solid forged steel, not hollow. 

Next, I am always looking for that extended warranty. I can conclude that the manufacturer is confident about their product if they put a warranty stamp on it. 

And finally, I look for a sway bar that’s compatible with my car. That’s logical enough. 

And the winner is the EIBACH ANTI ROLL REAR PERFORMANCE SWAY KIT

It fulfills all the quirks and concerns that I have as a car owner. It is made in the USA by a quality brand that has proven itself in the automotive industry. Many buyers even say that it outperforms their stock sway bars that will be replaced. 

I can install it by myself and won’t need fancy tools. Most reviews say that it can be fitted in less than 30 minutes. 

And I like that it’s made of aircraft-grade steel which is even more of my standard of solid forged steel. That’s durability to the max. 

And they have this extended warranty that I’m talking about. And delightfully, it’s a million-mile warranty which I know is an exaggeration because it’s near to impossible that my car will travel a million miles. This means this warranty is for a long long time. 

FAQ Section

Is a thicker sway bar better? 

Thicker and bigger are not always better. What you should be looking for are well-engineered sway bars with superior material. A great sway bar should complement the suspension, not overpower it. 

What is the difference between stock and aftermarket sway bars? 

Their differences are featured through stiffness, adjustability, and weight. 

Aftermarket sway bars, like the ones featured here, are lighter and stiffer and give more allowance to a wider range of adjustments. Many customers even say that aftermarket sway bars are even better than stock sway bars.
