DBA DBA43769XS 4000 Series XS Cross-Drilled Slotted Rear Brake Rotor

The DBA DBA43769XS is a high-performance 4000 Series XS brake rotor designed specifically for the Toyota Land Cruiser LC300 (2021 and newer) rear axle position. This premium single-piece rotor combines advanced metallurgy with distinctive cross-drilled and slotted design to deliver enhanced braking performance beyond OE specifications.

Advanced Construction and Materials:

• Cast from XG-150 high-carbon alloyed iron for superior heat resistance and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and maximizes thermal stability
• Patented Kangaroo Paw ventilation system features 144 diamond and teardrop-patterned pillars
• Up to 30% increase in surface area and 20% improvement in cooling efficiency versus traditional straight-vane designs

XS Cross-Drilled and Slotted Design:

• Non-directional cross-drilled and slotted pattern eliminates need for left/right specific rotors
• Gold-finished hub for enhanced appearance and corrosion protection
• Cross-drill and slot design evacuates brake pad friction dust and gases for more consistent stops
• Unique combination of dimples and drilled holes provides enhanced structural support over traditional cross-drilled techniques
• Painted non-friction areas prevent rust and enhance appearance

Performance Features:

• Designed for high-performance street applications and enthusiast drivers seeking upgraded braking
• Handles intense braking applications repeatedly without fade
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation
• Thermo-Graphic Heat Paint markings change color at specific temperature thresholds to assist with monitoring rotor performance

The DBA 4000 Series XS rotor is ideal for Land Cruiser LC300 owners who want enhanced stopping power with an aggressive cross-drilled and slotted appearance. While not recommended for extreme off-road or track use, this rotor excels in high-performance street driving and provides significantly improved braking over stock rotors.
