When shopping for a premium weight distribution hitch, two names often appear at the top of the list:

• Equal-i-zer® 4-Point Sway Control Hitch
• ProPride 3P® Trailer Sway Elimination Hitch

At first glance, both products appear to solve the same problem.

Both distribute weight.

Both are designed for bumper-pull travel trailers.

Both are widely recognized within the RV community.

However, once you look at the engineering behind each hitch, you'll find they approach trailer sway in fundamentally different ways.

The real question isn't simply "Which hitch is better?"

It's:

"Which engineering philosophy makes the most sense?"

Quick Comparison

How the Equal-i-zer® Works

The Equal-i-zer® 4-Point Hitch combines weight distribution with integrated sway control.

Its design uses:

• Trunnion spring bars
• Four friction points
• Steel-on-steel resistance
• Weight distribution brackets

As the trailer attempts to move side-to-side, friction develops at the contact points between the spring bars and brackets.

That resistance helps reduce trailer movement.

Many RV owners appreciate that the Equal-i-zer®:

• Combines weight distribution and sway control into one system
• Is available in multiple tongue weight capacities
• Has a relatively straightforward installation process for many applications
• Does not require a separate friction sway bar

However, because it relies on friction, the trailer still pivots conventionally around the hitch ball.

The sway-control system reacts after trailer movement begins.

How the ProPride 3P® Works

The ProPride 3P® uses an entirely different engineering approach.

Instead of relying primarily on friction, it uses patented Pivot Point Projection™ (3P) technology.

Its converging-link design projects the trailer's effective pivot point forward toward the rear axle of the tow vehicle when lateral forces act on the trailer.

At the same time, a patented one-piece yoke prevents conventional side-to-side pivoting at the hitch ball.

Rather than resisting trailer movement after it starts, the ProPride 3P® changes the effective geometry of the towing system.

Friction vs. Geometry

This is the biggest difference between the two hitches.

Equal-i-zer®

The hitch creates friction that resists movement after sway begins.

Think of it like applying brakes to an object that's already moving.

ProPride 3P®

The hitch changes the effective geometry of the towing connection.

Instead of relying on resistance, it addresses the mechanism that allows conventional sway to develop.

The difference isn't one of strength.

It's one of engineering philosophy.

What Happens in Crosswinds?

Crosswinds are one of the most common causes of trailer instability.

With any conventional hitch-ball connection, lateral wind forces can cause the trailer to rotate around the hitch ball.

The Equal-i-zer® counters this rotation with friction.

The ProPride 3P® addresses the forces through Pivot Point Projection™, changing how those lateral loads are transferred through the hitch system.

For RV owners who regularly tow across open plains, coastal highways, or mountain passes, this distinction can be an important consideration.

What About Passing Semi-Trucks?

When a tractor-trailer passes, the airflow typically creates:

• Initial pressure
• Vacuum as the truck draws alongside
• Secondary pressure wave

These rapidly changing aerodynamic forces test every towing setup.

A friction-based hitch resists the trailer's movement as those forces act.

The ProPride 3P® is engineered so that conventional side-to-side pivoting at the hitch ball is prevented, altering how those forces affect the tow vehicle and trailer.

Installation and Setup

Equal-i-zer®

Many owners report installation is straightforward, though initial adjustment may take time to optimize weight distribution and sway control.

Switching to a different trailer or tow vehicle may require readjustment.

ProPride 3P®

The ProPride 3P® has a more involved initial installation because of its advanced converging-link design and weight distribution system.

Once properly installed and adjusted, many owners appreciate its robust construction and compatibility with different tow vehicles through its adjustable hitch bar.

Maintenance

Equal-i-zer®

Maintenance generally includes:

• Lubrication where recommended
• Inspecting friction surfaces
• Monitoring wear on spring bars and brackets
• Checking fasteners

ProPride 3P®

Maintenance includes:

• Periodic lubrication of specified components
• Routine inspection of linkage and hardware
• Weight distribution jack maintenance
• Standard hitch safety checks

Both systems should be inspected regularly as part of safe towing practices.

Long-Term Ownership

Many RV owners begin with a friction-based hitch before upgrading later.

Reasons commonly cited include:

• Larger travel trailers
• Longer highway trips
• More frequent towing
• Desire for increased confidence
• Reduced driver fatigue

Because the ProPride 3P® is built with heavy-duty steel construction, an adjustable hitch bar, and a Lifetime Warranty, many owners view it as a long-term investment.

Side-by-Side Comparison

Which Hitch Is Best for You?

The Equal-i-zer® may be a good fit for RV owners who:

• Want an integrated weight distribution hitch
• Prefer a friction-based sway-control design
• Have a lower initial budget
• Tow occasionally

The ProPride 3P® is often chosen by owners who:

• Tow frequently
• Travel long interstate distances
• Encounter crosswinds regularly
• Want an engineering solution based on geometry rather than friction
• Plan to keep their hitch for many years
• Value premium construction and long-term ownership

Frequently Asked Questions

Is the Equal-i-zer® a weight distribution hitch?

Yes. It combines weight distribution with integrated four-point friction sway control.

Does the ProPride 3P® use friction to control sway?

No. The ProPride 3P® uses patented Pivot Point Projection™ technology and a one-piece yoke to address trailer stability through geometry rather than relying primarily on friction.

Which hitch is easier to install?

Many users report the Equal-i-zer® has a simpler initial installation. The ProPride 3P® requires a more detailed setup due to its advanced converging-link design.

Does either hitch increase towing capacity?

No. Neither hitch increases the manufacturer's rated towing or payload capacities of the tow vehicle.

Why is the ProPride 3P® more expensive?

The ProPride 3P® incorporates patented Pivot Point Projection™ technology, heavy-duty American-made construction, an adjustable hitch bar, premium components, and a Lifetime Warranty, resulting in a higher initial investment.

Is the ProPride 3P® worth upgrading to from an Equal-i-zer®?

That depends on your towing needs, trailer size, travel frequency, and priorities. RV owners seeking a geometry-based approach to trailer stability and long-term ownership often choose the ProPride 3P®.

Final Thoughts

The Equal-i-zer® and the ProPride 3P® are both respected products, but they were designed around two very different ideas.

The Equal-i-zer® seeks to reduce trailer sway through friction applied after movement begins.

The ProPride 3P® seeks to change the effective geometry of the towing system through patented Pivot Point Projection™, preventing conventional side-to-side pivoting at the hitch ball.

Neither approach changes your vehicle's tow ratings, and both require proper trailer loading and safe driving practices.

The choice ultimately comes down to how you believe trailer sway should be addressed.

If your goal is to manage sway with friction, the Equal-i-zer® offers an integrated and proven solution.

If your goal is to invest in a hitch engineered around geometry with the objective of eliminating the conventional mechanism that allows trailer sway to develop, the ProPride 3P® represents a fundamentally different approach—one rooted in physics rather than resistance.
