Jeep Wrangler Brake Rotor (1) - Front - DBA - 4000 Series Plain - `99-`06. A direct-replacement front rotor engineered by Disc Brakes Australia (DBA) for 1999–2006 Jeep Wranglers, offering improved thermal management and reliable, OE-style braking performance.

This DBA 4000 Series HD plain rotor is cast from XG-150 high carbon alloyed iron and undergoes Thermal Stability Profiling (TSP) to reduce the risk of thermal cracking and maintain consistent performance under repeated heavy braking. The rotor uses DBA’s patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars to increase surface area and cooling efficiency vs. traditional straight-vane designs. The HD variant provides a smooth OE-style face for drivers who want high-performance metallurgy while retaining a stock look. Rotors arrive in moisture-proof corrosion protection packaging and include Thermo-graphic paint (THGP) markings for heat monitoring.
