DBA DBA4719 4000 Series HD Rear Brake Rotor

The DBA 4000 Series is a direct replacement single-piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again.

Key Features:

• XG-150 high carbon alloyed iron construction with Thermal Stability Profiling for enhanced durability
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency
• Smooth OE-style rotor finish, ideal for drivers requiring an OE look such as controlled race divisions
• TSP process subjects XG-150 grey iron to prolonged heat cycles under strictly controlled conditions to relieve internal stresses and ensure maximum thermal stability
• Direct replacement fitment with no modifications required

DBA 4000 Series rotors deliver exceptional longevity, lasting on average 3 times longer than most other rotors on the market. The HD variant provides all the performance benefits of the 4000 Series with a clean, plain finish preferred for street use and certain racing applications. Sold individually.
