DBA DBA42676 4000 Series HD Front Brake Rotor 340mm

The DBA DBA42676 is a front 4000 Series HD brake rotor offering a significant upgrade over standard OEM braking performance. Featuring a smooth, OE-style rotor finish, this rotor is ideal for drivers who want the performance benefits of DBA's 4000 Series platform while maintaining a factory-style appearance — a popular choice for controlled race divisions and daily performance drivers alike.

Key Features:

• Direct OEM Replacement: Single-piece drop-in design engineered to replace factory rotors with no modifications required
• XG-150 High Carbon Alloy Iron Construction: Cast from premium high carbon alloyed iron for superior strength and fade resistance under intense braking
• Thermal Stability Profiling (TSP): DBA's proprietary metallurgical process enhances the rotor's ability to withstand and dissipate extreme heat generated during repeated hard braking
• Patented Kangaroo Paw Ventilation: Features 144 diamond and teardrop-patterned internal pillars, delivering up to 30% more surface area and 20% improved cooling efficiency versus traditional straight-vane designs
• Smooth OE-Style Finish (HD Variant): Clean rotor face without slots or drill holes — preferred for OEM-look requirements and controlled racing classes
• Rust-Resistant Painted Non-Friction Areas: Non-braking surfaces are coated to resist corrosion and maintain appearance over time
• Heat Indicator Paint Markings: Color-changing paint marks alert you to temperature thresholds, helping monitor rotor health and braking temperatures
• Micron-Level Surface Machining: Precision-machined rotor face for smooth pad bedding and extended pad life
• Diameter: 340mm | Axle Position: Front | Quantity Required Per Vehicle: 2

The DBA 4000 Series HD brake rotor is backed by DBA's engineering heritage as a leading manufacturer of performance and OE-replacement brake components. Sold as a single rotor; two are required per axle.
