Our Vehicle-Specific 6-Piston Big Brake Kit is engineered as a direct bolt-on upgrade for Toyota Tundra XK50/XK70 trucks. It’s built for owners who tow often, run larger-than-stock tires, or use their Tundra as a real work truck—not just a daily driver.
A large 6-Piston forged caliper and oversized 362 mm two-piece rotor work together to increase clamping force and heat capacity. You get a firmer pedal and more controlled stops when you’re coming down a long grade with a camper, boat, or car trailer behind you—while still fitting behind most factory 18"+ and compliant 17" wheels that meet the clearance requirement.
The data below shows how this kit is matched to the weight and towing capability of the Tundra platform. The piston area and rotor size are chosen to support heavy loads and frequent towing, while keeping pedal feel natural for daily driving. Every kit ships with our high-carbon rotors and M-01 street performance pads for quiet, consistent braking in real-world use.
