DBA DBA43031 4000 Series Rear Brake Rotor for Mercedes-Benz GL GLE GLS ML

The DBA DBA43031 is a high-performance rear brake rotor from DBA's 4000 Series line, engineered as a direct replacement upgrade for Mercedes-Benz GL-Class, GLE-Class, GLS-Class, and ML-Class SUVs. This single-piece brake rotor is designed for drivers seeking enhanced braking performance above standard OE levels while maintaining smooth, quiet operation.

Advanced Metallurgy and Heat Treatment:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment relieves internal stresses and optimizes rotor material before installation
• Enhanced fatigue resistance minimizes surface cracking under extreme braking conditions
• Handles increased stress and heat generated during intense braking applications repeatedly

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop patterned pillars for optimal airflow
• Achieves up to 30% increase in surface area compared to traditional straight vane designs
• Delivers up to 20% improvement in cooling efficiency for better heat dissipation
• Reduces brake fade and extends rotor and pad life

Premium Features:

• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation
• Painted non-friction surfaces prevent rust and enhance appearance
• Center split core castings for increased heat transfer and thermal efficiency
• Symmetrical design allows for universal left or right side installation

The 4000 Series Standard variant features a smooth OE-style rotor finish, making it ideal for drivers who want upgraded performance with factory appearance. This rotor provides consistent, reliable braking performance for heavy SUV applications while maintaining the quiet operation and long service life expected from premium brake components.
