Product Details

The DBA DBA42736 is a front 4000 Series HD brake rotor delivering upgraded braking performance above standard OE levels. Sold individually — two rotors are required per vehicle (front axle).

The 4000 Series HD variant features a smooth OE-style rotor finish, making it popular among drivers who want the performance benefits of the DBA 4000 Series with a factory appearance — ideal for controlled race divisions or daily drivers seeking a clean look.

Key Features:

  • Kangaroo Paw Ventilation: Features 144 diamond and teardrop-shaped pillars delivering up to 30% more surface area and 20% improved cooling efficiency over traditional straight-vane designs
  • High Carbon Alloyed Iron (XG-150): Premium iron formulation provides superior strength and durability under intense braking loads
  • Thermal Stability Profiling (TSP): Proprietary DBA heat treatment process that realigns the grain structure of the iron, maximizing thermal stability and reducing metal fatigue in high-demand applications
  • Thermographic Heat Paint Markings: Color-change paint indicators monitor peak braking temperatures and rotor fatigue at a glance
  • Vented Construction: Internal venting channels promote airflow and heat dissipation for consistent braking performance
  • OE-Style Smooth Finish: Clean appearance suitable for stock-look builds and controlled race classes
  • Direct Replacement: Single-piece design for straightforward installation with no modifications required

This part was hard to find and Mr. Clint Rathfon was very helpfully and he emailed when the order processed and when the order shipped. Because of him I will make sure me and all my friends buy pay parts from this company again and again.

It was great

Delivery and service were great. But the packaging of the spar fly was far too large.
