Product Information

Description:

CALIPER ASM,FRT BRK (B)

ACDelco Gold (Professional) Remanufactured Disc Brake Calipers are a high quality alternative to Original Equipment (OE) parts. ACDelco Gold (Professional) parts are manufactured to meet your expectations for fit, form, and function, making them a smart choice for General Motors vehicles, as well as most makes and models, including special applications. Remanufacturing disc brake calipers is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are replaced and are end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. These high-quality parts are backed by General Motors. Some ACDelco Gold parts may have formerly appeared as ACDelco Professional. ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov

Features and Benefits:

  • Remanufacturing is an industry standard practice that returns parts into service rather than scrapping them
