The latest Tundra and Sequoia platforms can tow and haul more than ever. The brakes have to keep up. Add a canopy or camper, armor, 35" tires and a big trailer and you quickly move beyond what the stock front system was comfortably designed for.
The OR6 front kit gives XK70 Tundra and XK80 Sequoia the kind of margin you expect from a serious tow and overland setup: forged 6-piston calipers with 79 cm² (12.25 in²) of piston area and 34 mm thick high-carbon rotors for high torque and strong heat capacity.
If your XK70 Tundra or XK80 Sequoia is built to tow hard and travel far, OR6 is the front brake package that closes the gap between stock hardware and how you actually use the truck.
The Tundra XK70 & Sequoia XK80 OR6 kit combines our off-road caliper architecture with a thicker rotor package to match modern full-size Toyota loads. The spec below is what makes repeated hard stops with weight on the hitch feel controlled instead of marginal.
