StopTech 71-86 Chevrolet K20 Suburban Cryo Slotted Front Left Sport Brake Rotor

StopTech Sport Rotors are also available with an optional cryogenic treatment. Although cryogenic treatment is invisible to the naked eye; many fleet customers are sold on its ability to extend the service life of the brake rotor. Deep cryogenic treatment is a one-time process that permanently improves the performance and wear characteristics of metal components; from brake rotors and engine parts to machine tools and gear sets. All new StopTech Sport Rotors may be ordered with cryogenic treatment for an additional fee.

Additional Information

Symmetric vane; split-core castings for uniform heat distribution. Black E-Coat anti-corrosive coating protects much better than competitors spray paint. Double disc ground friction surface for optimal performance and service life

Application Summary

1974 - 1988 Jeep J20

Product Overview

For drivers who need something even tougher than a standard StopTech Sport rotor, but are not ready for a big brake kit, StopTech offers cryogenically treated Cryo rotors.

Cryogenic treatment is a one-time stress relief process that involves both cold and heat cycling of the brake rotor. Using a proprietary computer-controlled process over a 24-hour period, the cryo machine gradually cools the rotors down to -300 º F, then gradually brings them up to over +300º F, and finally back to room temperature. This conditioning of the rotor improves its service life, especially in fleet and emergency vehicle applications.

Any new StopTech or Centric Premium 1-piece replacement rotor can by cryogenically treated prior to shipment. Cryo treatment typically adds 5-7 business days for processing.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.
