Engineered Different. Built to Last.

For nearly two decades, HHO Kits Direct has focused on one goal:

Build a hydrogen-assist system that we would trust on our own vehicles—and eventually on the world's most demanding engines.

While many systems simply adapt older designs, every generation of H₂XTRME has been engineered to eliminate weak points, simplify installation, and improve long-term reliability.

The result is a hydrogen-assist system built with the same philosophy found in professional industrial equipment:

Engineer it right the first time.

🔷 Purpose-Built Engineering

Every component was designed to work together as a complete system—not assembled from off-the-shelf parts.

🔷 Patented Innovation

Years of engineering resulted in patented technology that addresses problems found in conventional HHO generator designs.

🔷 Built for Reliability

From vibration resistance to leak prevention, every generation has improved through real-world testing and refinement.

🔷 American Designed

Proudly engineered by HHO Kits Direct with a commitment to quality, durability, and long-term performance.

Why We Engineered H₂XTRME Differently

There are two ways to build a hydrogen assist system.

One approach is to take an existing HHO generator, place it inside a larger enclosure, and call it a commercial system.

We chose a different path.

Every generation of H₂XTRME was redesigned to solve real-world problems discovered through years of testing and customer feedback.

  Leaks.

  Vibration.

  Maintenance.

   Durability.

  Reliability.

Instead of accepting those limitations, we kept engineering until we could eliminate or dramatically reduce them.

Because when a hydrogen assist system is installed on an expensive engine, reliability isn't optional.

It's expected.

That philosophy still guides every H₂XTRME system we build today.

15+ Years of Engineering. One Goal: Build It Better.
