The latest Tundra and Sequoia platforms tow harder, haul more and run larger wheels and tires than ever. The factory front brakes were not designed around a truck that’s near max Gross Combined Weight all the time.
The 7642TK kit is built for that use case: work trucks, tow rigs and family SUVs that live with payload, hitch weight and real miles. A forged 6-piston caliper with 63.5 cm² (9.84 in²) of piston area and 32 mm thick high-carbon rotors gives your Tundra or Sequoia the margin it needs when you’re coming off a mountain with a camper, boat or enclosed trailer behind you.
If your Tundra or Sequoia is used as a serious tow rig or loaded family hauler, 7642TK is the front brake upgrade that lets you use that capability with less drama at the pedal.
The 7642TK Tundra/Sequoia kit takes our heavy-load 6-piston hardware and tailors it to the latest Toyota full-size truck and SUV platform.

Ensure your Tundra or Sequoia is running 17" or larger wheels that can accept a front big brake kit.
Measure from the rotor mounting face to the back of the wheel spokes. You need at least 94 mm (3.7 in) of clearance.
Confirm your Tundra or Sequoia model year, engine and brake package. If you’re unsure, send us your VIN, wheel specs and how you use the truck, and we’ll help you verify fitment.

Look, we know you get it. Your brake kit is custom-made for your specific car. That means once it's built, it's yours. We can only accept returns if there’s a genuine quality defect from our side.
Sometimes, aftermarket wheels can be tricky. Depending on the design, you might need spacers for clearance. We’ll do our best to help you figure it out, but issues related to wheel spacers don't qualify for a return.
To get this right the first time, we need your help. Before you order, please give us the following info:
We’ll likely ask you to confirm some measurements and send a few photos of your wheels. Please double-check everything you send us. TTSPORT isn't responsible for fitment issues if the specs you provided were off.
