J.C. Whitney JSTPC27110099 Rear Vented Brake Disc OEM Replacement 8-Lug Plain Surface

The J.C. Whitney JSTPC27110099 is an OEM-replacement rear brake disc engineered as a direct-fit solution for heavy-duty GM trucks and vans. This vented, plain-surface rotor is designed to restore factory braking performance with a straightforward bolt-on installation requiring no modifications.

Key Features:

• Plain Surface Design: Smooth, flat rotor surface engineered for consistent pad contact and reliable stopping power under everyday driving and load-bearing conditions
• Vented Construction: Internal vane venting promotes airflow between rotor faces, dissipating heat and reducing the risk of brake fade during extended or heavy braking
• 8-Lug Hub Pattern: Designed for 8-lug heavy-duty truck and van applications, ensuring proper fitment on applicable GM platforms
• OEM Replacement Quality: Built to meet original equipment specifications for correct fit, form, and function
• Interchangeable Left/Right Fitment: RH=LH design simplifies ordering — a single part number covers both driver and passenger sides

OEM Cross-Reference: Replaces GM OEM part number 15712801.

Replacing worn or scored rotors promptly helps maintain consistent braking performance and prevents accelerated brake pad wear. For best results, it is recommended to replace brake pads at the same time as the rotors to ensure even wear and optimal contact.
