ACDelco 18A81999C Gold Fully Coated Rear Disc Brake Rotor

The ACDelco 18A81999C Gold Fully Coated Rear Disc Brake Rotor is a high-quality replacement disc brake rotor engineered to deliver dependable stopping power. Part of the ACDelco Gold (Professional) line, this rotor is a premium alternative to Original Equipment (OE) parts and is backed by General Motors.

Key Features:

• Fully Coated Construction: Robotically applied, baked-on rust-resistant coating helps prevent brake pulsation, resists rotor-to-hub seizing, and provides superior protection against rain, snow, and corrosive road spray
• Solid Rotor Design: Plain solid, non-slotted rotor with a smooth braking surface and 5-lug hole pattern
• OE-Grade Material: Cast iron construction using G3000 qualified material meets SAE standards for structural integrity
• Precision Manufactured: Thickness variation of less than 0.0004 inches minimizes pedal pulsation, reduces noise, and helps extend brake pad life
• No Machining Required: Ready to install straight out of the box — no break-in machining needed
• GM-Backed Quality: Manufactured to meet OE fit, form, and function expectations for GM vehicles and a wide range of other makes and models
• OEM Cross-Reference: Also known by GM base item number 19366024
