What is the benefit of cryogenic treatment on brake rotors?

Cryogenic treatment is a permanent process that reduces residual stresses within the metal. This makes the rotor more resistant to cracking from thermal stress and can extend its overall service life.

How do the slots on the rotor help my brakes?

The slots help to clear away brake dust and gases that build up between the rotor and pad. This keeps the friction surface cleaner and cooler, leading to a more consistent braking feel, especially in wet conditions.

Does this rotor come with any hardware?

This product is for the brake rotor only. You will need to reuse your existing hardware or purchase new hardware separately for installation.

Product Details

If you're working on the front brakes of your Chevrolet K20 Suburban, GMC K2500 Suburban, or Jeep J20 from the 70s and 80s, this StopTech Sport Rotor is a solid choice. It's designed as a direct replacement for your factory rotor, but with some key upgrades to help your brakes perform better and last longer. The slots on the rotor help to clear out dust and gas, which means you get a more consistent feel when you apply the brakes, especially in wet conditions.

What really sets this rotor apart is the cryogenic treatment. It's a special process that permanently changes the metal at a molecular level, reducing internal stresses. This makes the rotor much more resistant to cracking from heat and can extend its service life. The rotor also features a double disc ground friction surface for a consistent contact area with your brake pads, and a black E-coat finish that offers better corrosion protection than standard paint.

This rotor is built with symmetric vanes and split-core castings to help distribute heat evenly, which is crucial for preventing brake fade during hard stops. It's a well-built part that's designed to give you improved performance and durability for your truck or SUV.
