Hellwig vs. Roadmaster Sway Bar- Quick Differences

Bringing an RV or camper on your travels can be incredibly beneficial. These vehicles are equipped with various features that guarantee you have a pleasing experience on your trip. Besides, you can install extra appliances for your convenience. ​However, when it concerns driving these around, they might be challenging to steer due to their great size.

 In light of this, manufacturers have developed sway bars that may be mounted on your car. While some companies may give a stock one to their customers, these will still provide adequate sway to make sharp corners difficult. This is why it is usually preferable to have a third-party sway bar installed on your car.

Hellwig and Roadmaster are two of the best manufacturers of these gadgets. You may be unsure of the difference between the two. Thankfully, this article will guide you on the differences between these sway bars. Read through it keenly for a better understanding.

What you need to know about Sway bars

Nowadays, most automobiles have a sway bar, and some even are designed with two. However, they should be referred to as an anti-sway / anti-roll bar. Contrary to its name, a sway bar’s purpose is to prevent your car from tilting/rolling over in corners.

You’ve probably experienced this sensation in your car when you drive into a corner, particularly at high speed, and the vehicle leans or rolls to the outside away from the bend as you navigate it. The concept behind a sway bar is to produce a twisting force to counteract that tendency by applying a load to the opposite side of the car and leveling it out, eliminating body roll.

Cost of a replacement Sway Bar

Sway bar kits can cost as little as $200 to thousands of dollars. It all relies on the make and model of your vehicle, the brand you purchase, and the level of quality you prefer.

Why would you want to install a Sway bar?

The purpose of a sway bar, attached either to both the front and the rear wheels, is to oppose the vehicle’s tendency to roll when it curves, thereby increasing grip and cornering stability. The purpose of the sway bar is to attempt to maintain even distribution of weight from side to side.

As a result, one can install the sway bar in the front or rear, or both, to minimize under and over-steer. Certain performance vehicles include adjustable sway bars that can be tightened or loosened depending on your preference; customizable sway bars are also available aftermarket.

How a Sway bar works

How a Sway bar works

A sway bar resists twisting forces exerted when one tire swings up or down relative to the other when weight shifts from one side of the car to the other – such as when rounding a corner. In such circumstances, the bar keeps the wheels level.

The sway bar joins your vehicle’s suspension components and is attached to the suspension system arms. Sway bars go through bushings to prevent them from moving up and down and just twisting.

Thus, as the car rounds a corner, the weight shifts to one side. As the wheel approaches the trunk, the sway bar twists, forcing the weight to the opposite side of the vehicle. As a result of this motion, the car tends to level out, reducing roll while cornering.

Further factors are at work here, including the other suspension components and the engineers’ goal when tuning the vehicle’s ride and handling qualities. Additionally, there will typically be a difference in the ‘stiffness’ of the front and rear sway bars. This is critical to understand because, in general, manufacturers seek a balance of comfort and performance.

When one wheel collides with a bump, a stiff (or thick) sway bar will attempt to oppose the wheel motion (up or down), resulting in an overly rigid and uncomfortable ride. Additionally, based on how the remaining suspension is set, you may notice the vehicle bucking off the bump.
