First-gen Tundra and Sequoia are workhorses now, not light-duty commuters. Slide-in campers, steel bumpers, bigger tires, boats and car trailers all add up. The factory front brakes were never designed around a truck that’s a ton heavier than stock and towing on a regular basis.
The OR6 front kit is built for that life: forged 6-piston calipers with 79 cm² (12.25 in²) of piston area and 32 mm thick high-carbon rotors, giving XK50 Tundra and XK60 Sequoia a serious bump in torque and heat capacity for real-world towing and off-road use.
If your XK50 Tundra or XK60 Sequoia is doing truck work – hauling, towing, exploring – OR6 is the front brake system that lets it slow down with the same confidence it accelerates.
The Tundra XK50 & Sequoia XK60 OR6 kit uses our off-road hardware in a truck-specific configuration. The spec below is what turns a loaded, older full-size Toyota into something that stops like a modern heavy-duty system.
