DBA DBA43770S 4x4 Survival 4000 Series T3 Slotted Front Brake Rotor for Toyota LandCruiser 300 Series

The DBA DBA43770S is a 4x4 Survival 4000 Series T3 Slotted brake rotor engineered for the Toyota LandCruiser 300 Series (2021 and newer). Designed by Disc Brakes Australia (DBA), this heavy-duty rotor is purpose-built for demanding off-road and 4WD towing applications where standard rotors fall short.

The T3 Slotted surface uses DBA's patented tri-directional slot pattern to continuously clean, deglaze, and bite the brake pad surface — improving pad bite, reducing brake fade, and expelling heat, gas, and debris from the rotor face. This makes the DBA43770S an ideal upgrade for heavily loaded LandCruisers operating in remote, high-temperature, or mountainous terrain.

Key Features:

• 4000 Series T3 Slotted Technology — Patented tri-directional slots for consistent, high-performance braking
• 4x4 Survival Range — Engineered specifically for heavy-duty off-road and towing conditions
• Heat Dissipation — Slot design evacuates heat, gas, and debris to reduce fade
• Pad Deglazing — Keeps brake pad surface conditioned for optimal friction and bite
• Premium Metallurgy — High-grade cast iron construction for long service life and rotor integrity under load
• Corrosion Resistant Finish — Factory zinc-coated hat and edges to resist rust during storage and early use
• Direct OEM Replacement — Bolt-on fitment with no modifications required
• Australian Designed and Engineered — DBA is an ISO 9001 certified manufacturer with decades of motorsport and 4WD development

The DBA DBA43770S is sold as a single rotor. For full axle replacement, two rotors are required. Compatible with DBA and most leading aftermarket brake pad compounds. Manufacturer part number: DBA43770S.
