Forged 4-Piston Caliper
Two-piece forged aluminum body keeps caliper deflection low under high line pressure, so pedal travel stays short and predictable lap after lap.

Classic 5440 Front 4-Piston Big Brake Kit
The TTSPORT Classic 5440 is a front-axle 4-piston big brake kit built for drivers who want stronger initial bite, firmer pedal feel, and repeatable stopping power under heavy or repeated use. Two-piece forged aluminum calipers, staggered 38/41 mm pistons, and two-piece vented iron rotors work together to raise thermal capacity and tighten modulation versus an undersized factory setup.
Why Builders Choose the 5440
Staggered Piston Bores
38 mm × 2 leading and 41 mm × 2 trailing pistons load the pad evenly across the rotor face, reducing taper wear and helping bite stay consistent as the pad heats up.
Two-Piece Vented Rotors
Heat-treated high-carbon iron, internally vented, in Ø330 or Ø345 mm × 28 mm. Directional left/right design with curved-slot, grain-slot, wave-slot, or drilled-and-slotted faces.
Stainless Braided Lines
PTFE inner liner, SUS304 stainless braid, PVC outer sheath. Reduces line expansion for a firmer, more linear pedal under hard braking.

Will It Fit? Your 3-Step Check
The 5440 caliper requires a minimum 86 mm spoke clearance and a 17-inch or larger wheel. Always verify spoke profile, barrel shape, and offset against the caliper envelope before purchase. Caliper brackets and brake-line fittings are vehicle-specific.
1. Wheel Diameter
17-inch or larger wheels are required.
2. Spoke Clearance
Minimum spoke clearance is 86 mm. Spoke shape and offset matter as much as diameter.
3. Vehicle Model
The 5440 is a platform-adapted big brake kit. Caliper brackets and brake-line fittings are built for your specific vehicle. Confirm fitment with our team before ordering.

Installation & Break-In
- Caliper mounting uses radial mount with vehicle-specific brackets.
- Brake-line fittings are vehicle-specific on the caliper side and chassis side.
- Forged body and stainless lines keep system compliance low, so pedal pressure tracks linearly with deceleration.
- Two-piece vented iron rotors at 28 mm thickness shed heat across repeated stops, helping resist fade on canyon, track, or towing duty.
- A proper bedding-in procedure is required before hard use.
- Inspect and clean the caliper area more frequently in wet, dusty, salted, or high-debris environments.
Frequently Asked Questions
Will the 5440 caliper fit my wheels?
The caliper requires a minimum 86 mm spoke clearance and a 17-inch or larger wheel. Spoke shape and offset matter as much as diameter — confirm with a clearance check or contact us with your wheel specs.
What rotor size should I choose, 330 mm or 345 mm?
Both run 28 mm thickness. The 345 mm rotor adds thermal mass and leverage for heavier vehicles or repeated heavy braking; the 330 mm fits more wheels and is the lighter option for lighter cars.
Are the pads street-friendly?
The included pads operate from 0–600 °C with an average μ of 0.38, so they work cold on the street and continue to perform under track or canyon use. They are compatible with iron/steel rotors only.
Why are the pistons exposed without dust boots?
Star-profile racing pistons reduce heat transfer into the caliper during repeated hard braking. The trade-off is more frequent caliper cleaning in wet, dusty, or salted environments.
Is this a direct bolt-on kit?
The 5440 is a platform-adapted big brake kit. Caliper brackets and brake-line fittings are built for your specific vehicle. Confirm fitment with our team before ordering.
Do I need to bed in the brakes?
Yes. A proper bedding-in procedure is required to transfer pad material evenly to the rotor face and establish full bite, modulation, and fade resistance.

the "fit" is very precise
Style: BE-176H 1-Pack
Nice Fabrication, Good materials, perfect adhesive applications, "clean joints" etc.
Appears to be a good UPGRADE from the stock Motorcraft product.
CONs: The FIT was a "smidge TIGHT", and took very precise initial alignment and "pressure" to begin to slide into the rectangular hole. I measured the "Hole" at 7.375" wide, or (187.33 mm)... the FILTER is exactly the SAME.
I would suggest maybe reducing the Width by 1 mm, to allow for an easier installation.
The MOTORCRAFT uses an "open-cell" foam structure for the (2) Side pieces on their filter assembly, allowing some "compression to fit", of the Width, easing the difficulty of installation, yet still filling all voids.
In summation, the "fit" is very precise. Not to be hurried or rushed, maybe a bit meticulous for the impatient or weak of heart.

Breathe Easy!
Style: BE-728H 1-Pack
Ladies and gentlemen, buckle up, because we're about to embark on a whirlwind adventure of cleaner air and contortionist-worthy installation feats with the Spearhead HEPA Breathe Easy Cabin Filter!
First off, let's talk about installation. If you're someone who loves a good yoga session or considers themselves a Cirque du Soleil dropout, this is the filter for you. The instructions are so clear and helpful that even a goldfish could follow them. However, be prepared to twist and turn in ways you didn't know your body could. And let me tell you, I'm not in the best of shape. I discovered muscles I never knew I had and positions that would make a pretzel jealous. But don't worry, it's all worth it.
Once installed, my car’s air quality shot up faster than a rocket to Mars. And although my car is old and doesn't have any fancy AI, it felt like it was saying, "Ahh, finally, some quality air!" The air was so crisp and pure, I half expected to see little cartoon birds chirping around my head. And let me emphasize this: the product quality is top-notch. It not only works great but looks good too.
I purchased this gem because my wife has bad allergies, and so far, it's been a game-changer. She hasn't sneezed once, and the car doesn't smell as musty with the air conditioning on. It's like we've been transported to a fresh, alpine air paradise every time we drive.
In summary, the Spearhead HEPA Breathe Easy Cabin Filter is a game-changer. It's as easy to install as putting on socks—if putting on socks required you to become a human origami. But trust me, once it's in place, your lungs will thank you, and your car will feel like it's breathing the fresh, alpine air of the Swiss Alps. Five stars, and a standing ovation from my now incredibly limber body!

Great Cabin Filter Upgrade
Style: BE-729H 1-Pack, Style: BE-729H 1-Pack
I recently replaced my old cabin air filter with this one, and the difference was noticeable right away. Installation was quick and straightforward took less than 10 minutes with no special tools needed.
What I appreciate most is the air quality improvement. The airflow feels stronger, and there’s a clear reduction in dust, odors, and outside pollution entering the cabin.
If you’re looking for an easy, affordable upgrade that actually makes a difference in everyday driving comfort, this cabin filter is definitely worth it.
