Product Description

The **DBA 42737S 4000 Series T3 Rear Brake Rotor** is a high-performance direct-replacement rotor engineered for rear braking applications on select Toyota and Lexus SUVs. Designed with DBA's advanced tri-symmetrical T3 slot pattern and patented Kangaroo Paw ventilation system, this rotor improves brake pad engagement while helping remove gas, dust, and heat more efficiently than standard OEM rotors -- providing more consistent stopping power and smoother pedal feel under everyday driving and towing conditions.

Constructed from premium high carbon alloyed iron and processed with Thermal Stability Profiling (TSP) for enhanced durability and resistance to heat-related warping, the DBA 42737S offers stronger thermal performance and longevity compared with conventional rotors. Its slotted surface and corrosion-resistant painted areas help maintain brake performance and protect against rust over time. Ideal for drivers of Toyota 4Runner, Toyota FJ Cruiser, and Lexus GX460 models seeking improved rear braking performance without modifying their factory brake systems.
