Product Details

The DBA DBA43770 is a 4000 Series HD (Heavy Duty) front brake rotor engineered for the Toyota LandCruiser 300 Series (2021 and newer). As a direct OE-replacement single-piece rotor, it delivers a meaningful upgrade in stopping performance over the factory unit without requiring caliper relocation, brackets, or any additional hardware.

The 4000 Series HD variant features a smooth OE-style rotor finish, making it ideal for drivers who want the performance benefits of DBA's 4000 Series platform while maintaining a factory look — popular for fleet use, controlled race divisions, and daily-driven 4WDs that see heavy loads or towing duty.

Key Features:

  • High-Carbon Alloyed Iron Construction: Cast from premium XG-150 high-carbon alloyed iron for superior heat resistance and durability under intense, repeated braking.
  • Thermal Stability Profiling (TSP): DBA's proprietary metallurgical heat treatment process increases the rotor's capacity to handle constant and extreme heat over prolonged periods, reducing warping and hot-spotting.
  • Kangaroo Paw Vane Ventilation: Internal vane design features 144 diamond and teardrop-patterned pillars, delivering up to a 30% increase in surface area and up to 20% improvement in cooling efficiency compared to traditional straight-vane designs.
  • Smooth OE-Style Finish: The 4000 Series HD offers a clean, unslotted rotor face for a factory appearance while retaining all the metallurgical and thermal advantages of the 4000 Series platform.
  • Direct OE Replacement: Bolt-on fitment — no caliper relocation or additional brackets required.
  • Rust-Resistant Painted Non-Friction Areas: Non-braking surfaces are coated to prevent corrosion and maintain a clean appearance throughout service life.
  • Thermo-Graphic Heat Paint: Paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue.

The DBA DBA43770 is the smart choice for LandCruiser 300 Series owners who demand reliable, fade-resistant stopping power for towing, off-road, and heavy-duty daily driving — backed by DBA's decades of Australian engineering expertise.

Great price

Purchase was smooth and delivery was fast. Can't ask for much more

Right size and price !! will be a repeat customer!!

Great service and good prices

I had placed my order and then had been checking the confirmation email site for updates on processing and when it was shipped. It had been over a week with no updates noted just that the order was received. I emailed customer service to see if my order had shipped yet and was told they would check with the warehouse to check the status. They responded quickly to let me know what date it was shipped and provided tracking information. I appreciated the quick response and follow up by your customer service representative. Perhaps keeping the "progress of order" page updated to real time more often would be beneficial.
