LC300 and LX600 builds rarely stay close to stock weight. GVM upgrades, long-range tanks, bar work, underbody protection, roof loads and serious towing quickly turn them into true heavy vehicles.
The 7642TK front kit is engineered for that kind of duty. A forged 6-piston caliper with 63.5 cm² (9.84 in²) of piston area and 32 mm thick high-carbon rotors adds the thermal capacity and clamp force a loaded 300 Series or LX600 really needs on long, steep descents.
If your LC300 or LX600 is built to cross countries with real payload and towing, 7642TK is the front brake system that lets you use that capability without wondering if the brakes will keep up.
This kit uses our heavy-duty 6-piston architecture in a Land Cruiser 300 / LX600-specific configuration. The spec below is what turns a heavily built 300 platform into something that still feels composed halfway down the pass.
