J.C. Whitney SET-JC27110102-2 Rear Brake Disc Rotor Set Plain Vented 8-Lug OEM 15769474

The J.C. Whitney SET-JC27110102-2 is a rear disc brake rotor set designed as a direct OEM replacement, sold as a matched pair including both the driver side (LH) and passenger side (RH) rotors. This set replaces GM OEM part number 15769474 and is engineered to restore factory braking performance on Chevrolet Silverado 3500 and GMC Sierra 3500 trucks from model years 2001 through 2006.

These rotors feature a plain, smooth rotor surface combined with an internal vented construction that promotes airflow between the rotor faces to dissipate heat efficiently during heavy braking — a critical characteristic for high-GVWR trucks subject to demanding towing and hauling loads. The 8-lug bolt pattern matches the factory wheel hub configuration on these heavy-duty GM platforms.
