Gearbox and Prokennex are both superior manufacturers with unique technologies in the field of racquetball racquets.

But when it comes to the Gearbox vs. ProKennex, which is the right option for you?

In this article, we’ll take a closer look at each of these two products to help you evaluate your options and make the best choice for your game.

Gearbox vs. ProKennex: A closer look


Prokennex is a science and design company immersed in the racquet lifestyle.

They believe that creativity and innovation flows from the things that people find worthy of passionate pursuit. 

 The company motto states: “It’s not rocket science, but its racquet science”.

The science explained

According to the manufacturer:

QPlus Technology: Pro Kennex pioneers new material layup patterns and resin systems to replace frame chassis weight with 25% more kinetic energy chambers. 

This increase over its predecessor improves the heralded benefits of kinetic technology, redirecting even more wasted energy (shock, torque, vibration) and transferring it back to the ball in velocity and direction. 

With the incidence of arm energy at a historical high, improving the unique physics found in the kinetic system-which shields the player from harmful impact forces-has never been needed more than right now. 

The same Newtonian physics that protects your arm also yields the most efficient energy.

The transfer in racquet equipment boasts frame capacity while providing its protective shield for your health. 

This means more players playing longer, more often and playing better. 

Quadfocus: The latest evolution in kinetic science rethinks the application of Newtonian physics by componentizing the energy chambers and moving them to the four corners of the frame. 

This positions the chambers away from the most stable area of the frame to the most vulnerable, focusing energy more efficiently. 

Since the kinetic technology works on sensitive timing system, (like pistons in an engine), the quadrofocus design allows us to custom load the chambers based on location. 

Tip speed is much faster than hip speed! This function has unleashed a sweet spot like no other.

The virtual square vs. the normal oval shape found in conventional, mono mass systems. 

The cornered expansion gives the player an enormous advantage as the ball-strike moves away from the sweet spot, particularly in the 10-2 positions. 

The Stages of Technology as it is Integrated into the Prokennex Racquet include:

  • Stage 1: As you swing the racquet forward, micro bearings load to the back of 100 precision-engineered chambers integrated into the frame.
  • Stage 2: As the racquet impacts the ball, the loaded bearings explode forward to the front of the chamber transferring the resulting kinetic energy into the ball. 
  • Stage 3: After impact, a shock wave is released into the string bed from the ball and is immediately absorbed into the kinetic chambers around the racquet frame almost eliminating vibration to the arm. 


According to the manufacturer, the impetus for the formation of Gearbox was fueled by a vision to create superior, technology-based sporting equipment and at the core of all efforts, implementing a grass-roots model. 

History of Gearbox

Gearbox was founded in California by Rafael Filippini.

As a professional racquetball player, and with over 25 years of experience in the composites industry, he worked to hone his skills, creating revolutionary technologies while simultaneously fulfilling his dream to create a leading technology brand created by athletes for athletes. 

Gearbox expands

Gearbox continues to be synonymous with excellent quality, outstanding durability, and cutting edge technologies. 

Gearbox proudly expanded into pickle ball and Paddleball in 2015 to begin to introduce its innovative technologies to new sports. 

Gearbox wants players of all levels to experience first-hand how its quality products can improve their game and continue to support their love of sport. 

The future of Gearbox is an advanced collection of racquetball racquets, pickle ball and paddleball paddles, edgy apparel and high quality accessories. 

The company

As we mentioned earlier, Gearbox was conceived by the company’s founder, designer and pro-level racquetball player, Rafael Filippini. 

He created Gearbox to fulfill his vision of a racquetball only, design-driven brand. 

Every Gearbox product is thought about with serious and recreational racquetball players in mind.

His concept is simply to empower the racquetball community at large. 

Rafael Filippini shared his vision of a more organic racquet sports brand with his cousin Rafael Aguilo.

Rafael Aguilo was already an established entrepreneur. He dropped his other endeavors to pursue Rafael Filippini’s vision. 

Together they decided to build a company that was set up to design and manufacture the best quality products in the racquetball industry. 

Racquetball is a lifestyle at Gearbox

Gearbox is a company for a player designed by a player.

Seeing racquetball not only as a sport but as a great lifestyle, Gearbox wants to create a proud and enduring identity for the sport. 

Gearbox is committed to designing products for the racquetball player lifestyle, products that promote racquetball on and off the court.

Which is right for you?

In the section below, we will take a look at one product from each manufacturer.

Gearbox M40 170 Teardrop Racquetball Racquet

The Gearbox M40 line includes two key technologies not offered in any previous model. This collection is constructed using M40 High Modulus Graphite.

In addition, Gearbox engineers extended the internal C3 Power Groove to now run the entire inside length of the racquet. 

Together, these technologies give this collection a crisp, lively feel with even more power. 

You can view the Gearbox M40 170 Teardrop Racquetball Racquet at Amazon to learn more about how this product might work with your game.

Features include:

  • Patented solid head technology 
  • New M40 High modulus Graphite
  • Enhanced frame response 
  • Extended C3 power groove technology (explained below)
  • Maximized string deflection 
  • Power, control, durability
  • Maximized sweet spot
  • Vibration control
  • Displacement channels
  • Power string bed

What is C3 Power Groove? 

The C3 Power Groove technology is a single groove that extends an entire length of the racquet down to the throat area.

The C3 Power Groove creates three concave shapes in the structure of the racquet. 

  1. Radical Concave: Creates a larger hitting area, increasing the overall size of the sweet spot. Provides impact resistance at the head giving the racquet more strength.
  1. Double Radical Concave: Expands the main strings and cross strings to their maximum possible distance resulting in superior power and control.
  1. Progressive concave: Increases overall main strings length providing more power and control.

These three concave shapes in combination work synergistically to maximize power, control, and racquet strength. 

The C3 Power Groove also increases string deflection to its maximum distance resulting in exceptional power.
