The Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver (part number 631-48052R) is engineered for reliable braking performance on select GM and Isuzu vehicles. Designed with a vented, directional surface, this rotor enhances heat dissipation and braking consistency for models like the Chevrolet Trailblazer and GMC Envoy.

• Vented disc brake rotor with drilled and slotted surface
• Nominal thickness of 29.1 mm and discard thickness of 27.5 mm
• Directional braking surface for optimized performance
• Rust-resistant zinc silver hat finish with plain disc finish
• 6 bolt holes with 13.2 mm diameter and 127 mm bolt circle diameter
• Overall diameter of 302 mm and height of 54.7 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The drilled and slotted surface pattern aids in debris removal and gas venting, reducing brake fade under demanding conditions. The rotor's directional surface ensures proper rotation alignment for optimal performance and longevity.

Constructed with a plain disc finish and a zinc silver rust-resistant coating on the hat, this rotor offers protection against corrosion, extending its service life. The rotor measures 302 mm in outside diameter with a 79.2 mm center hole diameter, fitting securely on vehicles with a 6-lug, 127 mm bolt circle pattern. The nominal thickness of 29.1 mm and discard thickness of 27.5 mm provide clear service limits for maintenance.

About the DFC Brake Rotor - Drilled and Slotted - Silver Line
