Enhanced Metallurgy

Every brake rotor we make shares a common foundation in metallurgy. Because all metals are NOT made equal, we approach creating our brake rotors with a no-nonsense philosophy in casting them to fit your fleet vehicle requirements.

We promise 3 priorities in metallurgical design:

1. Safety

2. Compatibility

3. Performance

Corrosion Resistance

For vehicles that experience winter weather conditions and are expected to handle demanding environments, we say worry no more! Our rotors are designed for harsh climates, with a 600 hour corrosion rating, for any kind of muck.

That’s 200 hours longer than the SAE industry standard test of 400 hours.

Molecular Realignment

Building a superior brake rotor means finding a smarter way to transform its molecular structure. Our goal is to reduce tears and cracks in the microstructure of grey iron in order to create a more uniform surface area. Smooth = long life.

This means our rotors respond better to applied friction, allowing our metal to maintain a consistent surface area longer than other brake rotors, ultimately improving performance on the road.

brake rotors

Deep space science

for fleet vehicles

Cryo Rotor brake technology triples the life of traditional brake rotors by pairing our premium metallurgy with a NASA pioneered process, called deep cryogenic processing. We then triple heat temper to enhance our quench of metals, which we call cryogenic tempering, resulting in extended life to your brake rotors through a refinement of the molecular structure. TruBlue brake pads also last around 40% longer when used in conjunction with our Cryo Rotor brake rotors.

What Experts Say

Our brake rotors and pads were being changed almost monthly from other manufacturers. We've used Cryo Rotor brake rotors and pads for over a year and have yet to change any of them.

With tight tolerances on rotor quality and proper cryogenic treatments, brake rotor life may be extended as much as three times over comparable, non-treated parts.

200%+ Longer Life


Our clients often see 300-400% gains, but we guarantee at least double the life over any other brand of untreated brake rotors you're using currently.
