Hellwig vs. Roadmaster Sway Bar- The Best Sway Bar?

Traveling with an RV or motorhome can be hugely advantageous. These vehicles are designed with a variety of features to ensure that your trip is exciting. Additionally, users can add convenience appliances. However, due to their great size, these may be difficult to maneuver.

Manufacturers have responded by developing sway bars that can be installed on your vehicle. While some organizations may provide customers with a stock one, these will still have sufficient sway to make sharp corners nearly impossible. This is why it is typically preferable to have your car fitted with a third-party sway bar.

Hellwig and Roadmaster are two of the most reputable manufacturers of these devices. You might be unfamiliar with the distinction between the two. Fortunately, this article will outline the contrasts between these sway bars. To gain a better understanding, carefully read it through.

Sway bars: All you need to know

Nowadays, the majority of vehicles come equipped with a sway bar, some having even two. They should, however, be referred to as anti-sway / anti-roll bars. A sway bar’s function is to prevent your vehicle from tipping/rolling over when navigating corners.

You’ve probably felt this sensation while inside your car when you start driving into a corner, especially at high speed, and the car tends to lean or roll to the outside, away from the bend. A sway bar’s purpose is to generate a spiral force to counteract this tendency by applying a force to the other side of the vehicle and leveling it out, thereby eliminating body roll.

The cost of a new sway bar

Sway bar kits range in price from $200 to many thousands of dollars. It is entirely dependent on the make or model of your car, the model you select, and the quality you desire.

Importance of a sway bar to your vehicle

A sway bar, which can be attached to either the front or rear wheels, is designed to resist the car’s tendency to roll whenever it curves, consequently enhancing grip and cornering consistency. The sway bar’s purpose is to continue to maintain an even weight distribution from sideways.

As a result, the sway bar can be installed in the front or rear, or even both, to help reduce under and oversteer. Certain performance vehicles come equipped with customizable sway bars that can be tightened or loosened to your preference; aftermarket custom sway bars are also available.

How a sway bar operates

A sway bar withstands the twisting forces produced when one wheel swings up or down compared to the other when the car’s weight is shifted from one side to the other – as when leveling a corner. The bar maintains the wheel level in these circumstances.

The sway bar connects the suspension components of your vehicle and is connected to the arms of the suspension system. Sway bars are routed through bushings to protect them from rising and falling or simply twisting.

As a result, the weight of the car shifts patterns as it rounds a corner. The sway bar twists as the wheel gets closer to the trunk, pushing the weight to the other side of the vehicle. The car seems to level out as a consequence of this motion, which reduces roll during cornering.

Additional variables play a role here, such as the other suspension bushings and the engineers’ objective when tuning the car’s ride and handling characteristics. Additionally, the ‘stiffness’ of the front and back sway bars will typically differ. This is vital to understand since manufacturers generally strive to strike a balance between performance and comfort.

When one wheel comes into contact with a bump, a rigid (or thick) sway bar attempts to counteract the wheel’s rotation (up or down), resulting in an excessively rigid and uncomfortable ride. Additionally, depending on the setting of the remaining suspension, you may realize the car bucking off the bump.

Are stiffer sway bars better?

Are stiffer sway bars better

Sway bars that are stiffer can simulate the effect of a more rigid suspension. The ride will be stiffer, and the vehicle’s response to road imperfections will be quicker. Several modern autos, on the other hand, present a solution. For example, the Mercedes GLE is equipped with Active Body Control. The basic suspension and anti-roll bars incorporate active air suspension.

However, if you want to improve the performance of your car, stiffer sway bars can assist. They minimize body roll and tilt, providing a more stable and responsive driving experience. Additionally, they are inexpensive.

While stiffer sway bars are advantageous for high-performance cars and those that transport or tow heavy loads, anyone can adjust their drive if they believe sway bars provide an excellent driving experience. Stiffening the sway bars on a regular everyday vehicle, on the other hand, may exacerbate the problem.
