ACDelco 18A82458C Gold Fully Coated Front Disc Brake Rotor

The ACDelco 18A82458C is an ACDelco Gold (Professional) Fully Coated Front Disc Brake Rotor — a high-quality alternative to Original Equipment (OE) parts, backed by General Motors. This full cast, conventional-style rotor is designed to deliver reliable stopping power and long-lasting durability.

The rotor mounts to the wheel hub, where the brake caliper presses the brake pads against the disc surface to decelerate the vehicle. The full corrosion-resistant coating helps protect non-contact surfaces from rust and environmental damage, extending the service life of the rotor and helping prevent hub seizing.

Key Features:

• Fully coated construction — corrosion-resistant coating protects non-braking surfaces from rust, road salt, and environmental elements
• Full cast, conventional disc design — solid construction built for structural integrity under high heat and load
• Mill-balanced design — promotes smooth, quiet operation and reduces noise and vibration
• Tight thickness variation — minimizes pedal pulsation and helps extend brake pad life
• SAE structural integrity standard — manufactured using OE-matched G3000 grade cast iron for guaranteed performance
• No machining required — ready to install straight out of the box
• GM-backed quality — manufactured to meet GM expectations for fit, form, and function
• Sold individually — quantity: 1 rotor per pack
