TTSPORT 7642TK Heavy-Load 6-Piston Big Brake Kit for GWM Tank 300

If your Tank 300 lives on pavement and runs stock weight, you don’t need this kit. If you’ve added steel bumpers, winch, racks, tent, drawers and a full load of gear, you do.

The 7642TK system is built for Tank 300 owners who routinely run 1-ton+ of combined accessories, cargo and passengers on real terrain. A forged 6-piston caliper with 63.5 cm² (9.84 in²) of piston area and 32 mm thick high-carbon rotors gives you the thermal headroom the factory brakes simply don’t have when the truck is heavy and the descent is long.

  • Tank 300-specific mounting: 7642TK bolts to the factory knuckle and uses vehicle-specific brackets and one-piece rotors. No cutting, welding or master-cylinder swap – just a proper big-brake package that works with suitable 17" off-road wheels.
  • Heavy-load piston tuning: The 63.5 cm² piston area is chosen for loaded touring, not empty demo laps. Pedal effort stays familiar, but you get the extra clamp force you need when the truck is wearing armor, carrying camping gear and dragging a trailer.
  • Internal oil routing for rough roads: The caliper’s internal passages are laid out to keep pressure distribution even and bleeding straightforward, so corrugations, washboard and rocky climbs don’t turn pedal feel into guesswork.
  • One-piece 32 mm high-carbon rotors: 335 / 345 mm rotors add a lot of mass and surface area, which is what keeps braking consistent when you’re managing speed for minutes at a time instead of seconds.

Built properly, a Tank 300 carries more weight and sees harsher conditions than most factory test cycles imagine. 7642TK is the front brake system that matches that reality instead of the brochure version of the truck.

Will It Fit? Your 3-Step Check

Step 1: TTSPORT 7642TK Tank 300 brake kit requires 17-inch or larger wheels for fitment.
1. Wheel Diameter

Confirm your Tank 300 is running 17" or larger wheels that are suitable for a front big brake kit.

Step 2: Measure spoke clearance for the TTSPORT 7642TK Tank 300 kit.
2. Spoke Clearance

Measure from the rotor mounting face to the back of the wheel spokes. You need at least 94 mm (3.7 in) of clearance.

Step 3: Check your Tank 300 model and build details against the application list.
3. Vehicle Model

Confirm your Tank 300 model year and typical load-out (lift, tires, wheels, armor). If you’re unsure, contact us with your specs and we’ll help you verify fitment.

Frequently Asked Questions

Why choose 7642TK instead of a generic big brake kit on my Tank 300?
7642TK is built specifically around the Tank 300’s weight distribution, master cylinder and real-world overland use. The piston area, rotor size and internal oil routing are chosen for heavy trucks that spend time on rough roads and long descents, not just one hard stop on smooth pavement.
Will the brakes feel too aggressive when the truck is empty?
No. You’ll notice a firmer, more confident pedal, but initial bite is still easy to modulate in traffic. The goal is stable, predictable braking with a full load – not a race-car snap that makes the truck unpleasant to drive around town.
Is 7642TK compatible with lifts, 33–35" tires and aftermarket wheels?
In most cases, yes. The key is wheel barrel and spoke clearance. As long as you’re on 17" or larger wheels that clear the caliper profile, the kit works well with common Tank 300 off-road builds. If you’re unsure, send us your wheel brand, size, offset and a photo and we’ll help you check.
What’s included in the 7642TK Tank 300 front kit?

  • 2x TTSPORT 7642TK 6-Piston Forged Calipers

Heads 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.

  1. 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.
  2. 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.
  3. 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

  1. 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.
  2. Brakes feel different in the rain. Give yourself some extra stopping distance.
  3. 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.
