StopTech 126.68001CSL Cryogenic Slotted Front Left Sport Brake Rotor for Chevrolet K20 Suburban

Description

The StopTech 126.68001CSL sport brake rotor is engineered to deliver superior braking performance and durability for select Chevrolet K20 Suburban models from 1971 to 1986. Constructed with precision split-core castings and featuring a symmetric vane design, this rotor ensures uniform heat distribution during heavy braking, reducing the risk of warping and cracking. Its black E-Coat anti-corrosive coating provides exceptional protection against rust and corrosion, significantly extending the rotor’s service life compared to standard spray-painted alternatives. The double disc ground friction surface optimizes braking efficiency and ensures a consistent, smooth pedal feel while enhancing overall stopping power. This rotor has been inspected for balance and mill-corrected to a tolerance of less than 2 ounces, resulting in a more refined and reliable braking component. For those seeking enhanced performance, the rotor can be ordered with optional cryogenic treatment, a process that improves wear characteristics and extends service life by reducing residual stress within the metal. Designed as a direct OE replacement, this rotor is suitable for both street driving and demanding conditions, including wet weather scenarios where increased initial bite and gas evacuation are critical. The inclusion of slots on the rotor helps efficiently evacuate gasses, dust, and heat, further improving braking response and reducing fade. Whether for restoration, upgrade, or routine maintenance, the StopTech sport rotor offers a high-quality, durable solution that meets or exceeds OEM standards, ensuring safety, reliability, and optimal braking performance over the lifespan of your vehicle.
