Detailed Product Description

This disc brake rotor features a vented design that promotes airflow to reduce heat buildup during braking. The drilled and slotted surface enhances pad cleaning and gas release, which helps maintain consistent braking performance. With a nominal thickness of 29 mm and a discard thickness of 26.5 mm, the rotor provides a balance between durability and performance. The zinc black hat finish and rust resistant coating protect against corrosion, extending the rotor's service life. The directional surface design ensures efficient water and debris removal, which is critical for vehicles like the Chevrolet Avalanche 2500 and GMC Sierra 1500 HD operating in varied environments.

Applications and Problem Solving

• Compatible with Chevrolet, GMC, and Hummer heavy-duty trucks and SUVs
• Addresses brake fade caused by excessive heat during towing or heavy loads
• Reduces rotor warping and cracking through vented design
• Improves braking consistency in wet or muddy conditions with directional surface
• Prevents rust and corrosion for longer rotor lifespan

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (26.5 mm) before installation
• Use proper torque specifications for the 8 bolt holes (16.5 mm diameter)
