Weight Distribution Hitch vs Sway Bar – A Complete Comparison

The two things that often go hand in hand are weight distribution hitches and sway bars when it comes to towing. In this guide, we will be discussing both of these in detail and highlight how these two are different.

Before we discuss both the accessories in detail, it is important to know what they are.

What is a Weight-Distribution Hitch?

A weight-distribution hitch(WDH) is a tool/accessory that ensures the stable handling of the vehicle. In other words, WDH makes the weight more evenly between each axel of the trailer,

What is a Sway Bar?

Similarly, a sway bar has two arms and some bends to fit under the engine of the vehicle. Its basic purpose is to keep the vehicle level and handling straight while you’re making turns.

Weight Distribution Hitch vs Sway Bar: The Major Difference

Many people mistake WDH and a sway bar for similar types of equipment. Remember that both are different and offer distinctive utilities  Here are some main differences that will help you distinguish between the two:

  • A sway bar helps only with the sway, whereas a WDH helps with a sway as well as distributes the weight of a trailer
  • A WDH allows the trailer to be backed into place without being taken off, whereas the sway control bar must be removed before backing into a place.

What are the Benefits of WDH?

Moving a step further, let’s discuss the benefits of WDH. As you know, a WDH is used for the distribution of weight which makes it essential for every towing vehicle. Now WDH comes with numerous benefits. Some of these benefits are the following:

  • Extremely important to maintain control at highway speeds
  • WDHs help to reduce sway
  • Provides a more leveled and smooth ride
  • Offers consistent steering and brake control
  • Enhances the towing safety

What are the Problems Associated with WDH?

No matter how high-quality a product is, it will have its benefits as well as some problems.

As we talked about its benefits, it is also important that we highlight some of the problems associated with WDH:

  • Not suitable for steep/uneven terrain
  • Can bend the trailer’s frame
  • A low hitch paired with a WDH may have minimal ground clearance causing interference problems
  • Can crack the chassis if WDH action is too severe

What are the Benefits of a Sway Bar?

After a detailed discussion of the benefits and problems of a WDH, let’s move on to sway bars.

Now, if a weight-distribution hitch is not your thing, then you may be interested in sway bars. Now, like WDHs, it also has some amazing benefits:

  • Offers better handling
  • Has the ability to dial out some of the understeers
  • Avoid vehicle body to roll in turns
  • Balance the car’s weight by keeping more weight on the inside cornering tires
  • It keeps the occupants more comfortable
  • Effective in reducing sway 
  • Prevents violent movement of the mass of the car
  • Resists the leaning of the car

What are the Problems Associated with the Sway Bar?

Like WDHs, sway bars also have some problems associated with them:

  • Get noisy
  • Require readjustment
  • Transmit more bumps and vibration to the chassis
  • Not suitable for bumpy roads

How Does a WDH Work?

It’s Important to know how each works so now we’ll be having a look at each functionality. Let’s talk about WDH first.

A WDH works by distributing the tongue weight across the axles of the vehicle. If there isn’t a WDH system in the vehicle, then the tow vehicle’s rear axle load increases because of leveraging the tongue weight.

Consequently, the front axle load decreases. These axles load changes make the tow vehicles un-level. The decreased load on the front axle leads to loss of steering control and braking difficulties.

To put it simply, a weight distribution system allows the tow vehicle to effectively handle the tongue weight of a trailer by removing some of the load from the tow vehicle’s rear axle and distributing it evenly to the tow vehicle’s front axle and the trailer’s axle.

How does a Sway Bar Work?

If you are more of a sway bar person, you must know how that works. It is a torsional spring that keeps its shape by springing back into place.

It is fastened to arms that connect to your vehicle’s body. Thus whenever the body starts to roll or sway in one direction, the bar twists and pulls the lifting side back down, providing enhanced stability and handling by keeping the vehicle flatter to the road surface.

Which is Better: WDH or Sway Bar?

For the bottom line, I would say that both WDH and sway bar are the best for the purpose they are used for. However,I will say that WDH is better because of the little edge over the sway bar. The edge is that WDH distributes and also helps with the sway, which means it does the work of a sway bar.
