The Power Stop - Front Drilled, Slotted and Zinc Plated Brake Rotor Pair (Part Number AR8655XPR) is engineered for reliable braking performance on heavy-duty Chevrolet and GMC trucks. Designed specifically for models like the Silverado 2500 HD and Sierra 3500, this rotor set offers enhanced heat dissipation and corrosion resistance.

• Front drilled and slotted surface for improved heat and gas dissipation
• Zinc plated coating to resist rust and corrosion
• Vented rotor design for better cooling during heavy braking
• Compatible with Chevrolet and GMC 2500 and 3500 series trucks
• Includes two rotors with an outside diameter of 325 mm (12.80 inches)
• Mounting bolt hole circle diameter of 165.10 mm with 8 lug holes
• Nominal thickness between 36.50 mm and 38.10 mm for durability

Detailed Product Description

This Power Stop rotor pair features a vented design that helps maintain optimal braking temperatures by allowing air to flow through the rotor. The front drilled and slotted surface improves brake pad bite and helps evacuate brake dust and gases, reducing brake fade during demanding driving conditions. The zinc plating provides a rust-resistant coating, extending the rotor's service life, especially in environments prone to moisture and road salt.

With an overall height of 89.00 mm and a discard thickness of 1.44 mm, these rotors meet the specifications required for heavy-duty applications. The 8-lug hole pattern and 165.10 mm bolt circle diameter ensure proper fitment on Chevrolet Avalanche 2500, Express 2500/3500, Savana 2500/3500, Sierra 2500 HD/3500, and Silverado 2500 HD/3500 models.

Power Stop - Front Drilled, Slotted and Zinc Plated Brake Rotor Pair Line

The Power Stop - Front Drilled, Slotted and Zinc Plated Brake Rotor Pair product line focuses on delivering rotors that combine enhanced braking performance with corrosion resistance. This line is designed for vehicles that require reliable stopping power under heavy loads and frequent braking, such as full-size trucks and commercial vans. The drilled and slotted design improves heat dissipation and pad cleaning, while the zinc plating protects against rust, making it suitable for long-term use in demanding conditions.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Improves braking performance under heavy load conditions
• Reduces brake fade during extended downhill driving or towing
• Prevents rust buildup that can lead to uneven braking
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

• Ensure compatibility with Chevrolet and GMC 2500/3500 series models before installation
• Inspect brake pads and replace if worn to maximize rotor performance
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque lug nuts to manufacturer specifications for safety
• Check rotor thickness regularly and replace when discard thickness of 1.44 mm is reached
