What is the Kangaroo Paw ventilation system?

The Kangaroo Paw is DBA's patented ventilation design that uses a series of 144 diamond and teardrop patterned pillars. This design increases the rotor's surface area and cooling efficiency compared to traditional straight vane rotors, helping to dissipate heat more effectively.

What does 'Thermal Stability Profiling' mean for this rotor?

Thermal Stability Profiling is a heat treatment process that DBA applies to their rotors. It helps to handle the increased stress and heat generated during intense braking, ensuring the rotor maintains its integrity and performance over time.

Does this rotor come with hardware or brake pads?

This product listing is for the DBA 4000 Series HD front brake rotor only. Brake pads and any necessary installation hardware are sold separately.

About this part

Product Details

The XG-150 high carbon alloy iron used in this DBA 4000 Series HD rotor is a key ingredient for handling the heat and stress of hard braking. This material, combined with DBA's Thermal Stability Profiling process, means the rotor can take repeated abuse without warping. If you're driving a 2003-2009 Lexus GX470 and need a solid replacement for your front brakes, this rotor is built to last.

What really sets this rotor apart is the Kangaroo Paw ventilation system. Instead of standard straight vanes, it uses a pattern of 144 diamond and teardrop pillars. This design increases the surface area by up to 30% and boosts cooling efficiency by 20% compared to traditional rotors. This means better heat dissipation, which helps prevent brake fade during demanding use. The smooth, OE-style finish makes it a popular choice for drivers who want the performance benefits without a flashy look, making it suitable for controlled race divisions or just a clean appearance on the street.

This rotor is designed as a direct replacement for your GX470, specifically for models equipped with the 338mm front rotor and 13WH caliper casting. It's a well-built component that offers improved thermal management for more consistent braking performance.
