DBA DBA42768 4000 Series Plain Front Brake Rotor

The DBA DBA42768 is a 4000 Series plain (non-slotted) front brake rotor engineered as a direct, bolt-on replacement. Part of DBA's acclaimed 4000 Series lineup, this rotor delivers a meaningful performance upgrade over standard OEM rotors without requiring any mechanical modifications for installation.

DBA's 4000 Series rotors are cast from XG-150 high carbon alloyed iron and subjected to DBA's proprietary Thermal Stability Profiling (TSP) process — a treatment that realigns the microstructure of the iron to increase dimensional stability, improve heat tolerance, and minimize the risk of surface cracking under intense or prolonged braking. The result is a rotor that maintains consistent stopping power under demanding street and performance conditions alike.

Key Features:

• XG-150 High Carbon Alloyed Iron Construction — Premium alloy formulation optimized to work in conjunction with DBA's TSP heat treatment process
• Thermal Stability Profiling (TSP) — Proprietary DBA process that increases fatigue resistance and reduces warping under extreme heat cycles
• Thermographic Heat Paint (THGP) — Paint markings on the rotor edge permanently change color when temperature thresholds are exceeded, allowing monitoring of rotor health and braking temperatures
• Kangaroo Paw Ventilation — DBA's patented internal ventilation system featuring 144 diamond- and teardrop-shaped pillars for up to 20% improved heat dissipation over conventional straight-vane designs
• Direct Replacement Fit — Bolts directly onto the vehicle with no modifications required
• Anti-Rust Protection — Painted non-friction surfaces resist corrosion and maintain appearance
• Moisture-Proof Corrosion Protection Packaging — Ensures rotor arrives in ready-to-install condition
• Plain (Non-Slotted) Surface — Smooth friction surface for quiet, refined braking suited to street and daily performance driving

DBA (Disc Brakes Australia) has grown from its origins as a family-owned Australian manufacturer in the 1970s into a globally recognized brake technology leader. The 4000 Series is recommended for a wide range of applications including street driving, SUVs, light utility vehicles, track days, and armored vehicles. Sold individually.
