xThe Bolt-On Solution for Toyota Tundra XK50 & Sequoia XK60
Our Vehicle-Specific AR6 6-Piston Big Brake Kit is a direct bolt-on upgrade for Toyota Tundra XK50 trucks and Sequoia XK60 SUVs. It’s built for owners who actually use these vehicles for what they’re made to do: towing campers and boats, hauling tools and gear, loading up the family, and driving long grades with real weight on board.
A large 6-piston forged caliper and oversized 362 mm two-piece rotor work together to increase clamping force and heat capacity over the stock setup. The result is a firmer, more confident pedal and more controlled stops when you’re coming down a mountain pass with a trailer, a full bed, or three rows of passengers—while still clearing most factory 18"+ wheels and 17" wheels that meet the clearance requirement.
Technical Specifications & Kit Options
The numbers below show how this kit is matched to the weight and towing capability of the Tundra XK50 and Sequoia XK60 platforms. Piston area and rotor size are chosen to support heavy loads and frequent towing while keeping pedal feel natural in daily traffic. Every kit ships with high-carbon rotors and our M-01 street performance pads for quiet, consistent braking in real-world use.

Will It Fit? Your 3-Step Check
1. Wheel Diameter
Confirm your Tundra XK50 or Sequoia XK60 is running 17" or larger wheels.
2. Spoke Clearance
Measure from the rotor mounting face to the back of the wheel spokes. You need at least 102 mm (4.02 in) of clearance.
3. Vehicle Model
Use the vehicle filter or contact us with your Tundra/Sequoia year, engine, and trim so we can confirm the correct kit for your setup.
Want a printable fitment template? Contact us with your vehicle's year, make, and model, and we'll email you a 1:1 wheel-clearance template.
Frequently Asked Questions
Is this kit a direct bolt-on for my Tundra or Sequoia?
Yes. For the listed Tundra XK50 and Sequoia XK60 applications, the AR6 kit is designed to bolt to factory mounting points. No cutting, drilling, or fabrication is required—installation is similar to a standard front brake service with caliper and rotor replacement.
Will this really fit my factory wheels?
This system was engineered around common Tundra and Sequoia wheel packages. It is compatible with 17" or larger wheels that provide at least 102 mm (4.02 in) of spoke clearance. Most OEM 18"+ wheels meet this requirement, but because aftermarket designs vary, we recommend confirming with our printable template or contacting us with your wheel specs before ordering.
What's the main benefit for towing and heavy hauling?
Shorter, more controlled stops under load. Stock brakes can overheat quickly when you’re near the vehicle’s rated capacity—whether that’s a Tundra with a full bed and trailer or a Sequoia with three rows of passengers and gear. The larger 6-piston caliper and 362 mm rotor add both clamping power and heat capacity, helping you keep a consistent pedal and predictable stopping distances on long grades and in stop-and-go traffic.
What’s included in the AR6 front kit for Tundra XK50 & Sequoia XK60?
Yes, this is a complete, vehicle-specific front big brake kit. Each kit includes:
- 2x 6-Piston Forged AR6 Calipers
- 2x 2-Piece 362 mm High-Carbon Steel Rotors
- 1x Set of M-01 Street Performance Brake Pads
- 2x Stainless Steel Braided Brake Hoses (Tundra/Sequoia-specific)

xHeads Up! What to Know Before You Install
You’re here because you’re passionate about your ride, and so are we. We want your TTSPORT brake upgrade to be a total win. Here’s some straight talk to make sure everything goes smoothly, from fitment to bedding in.
Our Return Policy
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.
1. Let's Nail the Fitment
To get this right the first time, we need your help. Before you order, please give us the following info:
- Your vehicle's Make, Model, Year, and VIN.
- Your wheel size and specs.
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.
We check every single part before it leaves our shop. When your kit arrives, give it a good look-over. If you spot any potential quality issues, let us know within 24 hours.
2. The Fun Part: Bedding In Your New Brakes
This is key to awesome performance. Don't skip it.
- Find a safe, open road. Bring your car up to 40 mph (approx. 65 km/h) and apply firm, steady pressure to slow down to 10 mph (approx. 15 km/h). Don't come to a complete stop. Do this 10 times to get the pads and rotors acquainted.
- For the next 300-600 miles (approx. 500-1,000 km), take it easy. No crazy hard stops. This cures the pads and rotors and ensures a long, happy life.
- You'll notice our high-carbon steel rotors have a colored, grooved surface. This isn't just for looks—it helps speed up the bedding-in process and fights off corrosion.
3. Our Promise: The TTSPORT Warranty
We build our kits to last, and we stand by our work. Here’s the breakdown:
- Calipers: Covered for 1 year against manufacturing defects. We also offer lifetime maintenance (you just pay for parts).
- Rotors & Hoses: Covered for 90 days against manufacturing defects. These are wear items, but you can expect them to last 25,000-35,000 miles (approx. 40,000-60,000 km) depending on your driving style.
- Brake Pads: Covered for 90 days against manufacturing defects. Typically good for 15,000-25,000 miles (approx. 25,000-40,000 km).
- Custom Hats/Brackets: We guarantee they'll fit perfectly out of the box. Once they're installed, they're not covered under warranty.
4. Pro Tips for Long-Lasting Performance
- After a session of hard driving, let your brakes cool down naturally. Don't spray them with cold water—that's a fast way to warp rotors.
- Brakes feel different in the rain. Give yourself some extra stopping distance.
- If you hear or feel anything weird—grinding, shaking, etc.—talk to your installer right away.
Recommended Service Intervals:
- Rotors: Replace them when wear exceeds 3 mm (approx. 0.12 inches).
- Front Pads: Plan on swapping them every 20,000 miles (approx. 32,000 km) or so.
- Rear Pads: Usually last longer, around 35,000 miles (approx. 56,000 km).
- Brake Fluid: Flush and replace every 25,000 miles (approx. 40,000 km) or every 2 years, whichever comes first.
- Choosing a selection results in a full page refresh.
