DBA 4000 Series T3 Slotted Front Brake Rotor - Toyota 4Runner / FJ Cruiser / Lexus GX460 2010-2023

The 4000 Series T3 is a direct replacement front rotor cast in high carbon, heat treated iron and machined with DBA's tri-symmetrical bi-directional slotting, which multiplies the exit points for pad friction dust and brake gases so the friction surface stays clean and pedal response stays consistent. Behind the face sits DBA's patented Kangaroo Paw ventilation, a dense array of small pillars in place of conventional straight vanes that moves more air through the disc and spreads heat more evenly across the braking surface. The disc measures 338mm in diameter and 32mm thick with a 68.5mm height and a 29mm minimum machining thickness, and mounts on a 6 x 139.7 bolt pattern with a 108mm centering diameter. It is sold individually, so two are required to do the front axle.
