DBA DBA4888 Series HD Front Vented Disc Brake Rotor - 4000

The DBA DBA4888 is a 4000 Series HD front vented disc brake rotor engineered as a direct-fit, single-piece performance upgrade over standard OEM brake rotors. Featuring DBA's signature Kangaroo Paw ventilation technology, this rotor delivers superior cooling and braking confidence for everyday drivers and performance enthusiasts alike.

Key Features:

• Kangaroo Paw Vane Design: 144 diamond and teardrop-patterned pillars increase surface area by up to 30% and improve cooling efficiency by up to 20% compared to traditional straight-vane designs
• High Carbon Alloyed Iron Construction: Cast from XG-150 high carbon iron for superior heat resistance and long-term durability under intense braking conditions
• Thermal Stability Profiling (TSP): DBA's proprietary heat treatment process subjects each rotor to controlled heat cycles to relieve internal manufacturing stress, maximize thermal stability, and reduce metal fatigue
• HD Smooth Finish: OE-style smooth rotor surface — ideal for drivers who want the performance benefits of the 4000 Series with a clean, factory look; also accepted in controlled race divisions requiring OE-style appearance
• Rust-Resistant Coating: Non-friction areas are painted to prevent corrosion and maintain a clean appearance throughout the rotor's service life
• Precision Machined Surface: Rotor face is machined to micron-level tolerances for smooth pad contact, healthier bed-in, and reduced premature pad wear
• Temperature Paint Markings: Color-change paint indicators monitor braking temperatures and alert to rotor thermal fatigue thresholds

The DBA 4000 Series HD is a direct OEM replacement brake rotor designed for drivers seeking a meaningful performance upgrade above stock braking levels. Its combination of high carbon metallurgy, advanced ventilation, and thermal profiling makes it well-suited for demanding street use, off-road applications, and towing duty cycles.
