2007-2021 Toyota Tundra (XK50) & 2008-2022 Toyota Sequoia (XK60) OR6 Direct-Mount Front Big Brake Kit
The TTSPORT OR6 Front Big Brake Kit is built for loaded Toyota Tundra (XK50) and Sequoia (XK60) builds — overland weight, larger tires, armor, winch, roof tent, towing, and long mountain descents. A forged 6-piston caliper, Ø355 mm × 32 mm one-piece high-carbon iron rotors, and stainless-steel braided lines deliver predictable pedal feel and the thermal headroom factory front brakes were never asked to provide.
Why Toyota Tundra XK50 & Sequoia XK60 Builders Choose the OR6
A stock Tundra or Sequoia front system is sized for stock weight on stock tires. Add steel bumpers, a winch, drawers, a roof tent, long-range fuel and water, plus 33–35 in tires, and the front axle works harder on every stop. That extra mass and rotational inertia turns into heat, longer pedal travel, and fade on washboard descents and trail approaches. The OR6 front kit is engineered for that real-world load profile — not lap times.
6-Piston Clamping Balance
Staggered 40 mm and 43 mm pistons even out pad pressure and reduce taper wear under heavy loads.
Application-Correct Rotor Size
Toyota Tundra (XK50) and Sequoia (XK60) use the OR6 Ø355 mm × 32 mm front rotor specification.
Heat-Insulated Pistons
One-piece heat-insulated pistons with dust boots help protect seals from trail heat, dust, and water crossings.
PTFE / SUS304 Braided Lines
Three-layer PTFE / SUS304 braided lines reduce expansion under load for a firmer, more predictable pedal.
Daily, Tow & Trail Use
Built for overland trucks that see highway towing, rough access roads, and sustained descents.

Great t shirts
Number of Items: 5, Color: Navy/Heather Navy/Indigo Blue, Size: Large
Great t shirts. They fit great, and are very comfy as an under shirt or just a solid color shirt. Have washed them multiple times and they still hold up good, don’t wrinkle easy, and colors have stayed nice. The fit is great, can definitely be used for work, gym, whatever, just good comfy shirts

Bought in multiple colors! Fantastic material
Size: X-Large, Color: Light Green, Size: X-Large, Color: Light Green
I ordered this button-up for an upcoming beach vacation, and I’m honestly so impressed with the quality and feel of it. Right out of the package, the material felt soft, breathable, and exactly what you want when you know you’ll be spending long hours in the sun and heat. It’s incredibly lightweight without feeling cheap or flimsy, which was one of my biggest concerns when ordering.
What I really love is how well it helps keep you cool. The fabric allows for great airflow, so you don’t feel like you’re overheating or sweating through it like you might with heavier shirts. Even just trying it on, I could tell it’s going to be perfect for hot, humid weather. The fit is also spot-on—not too tight, not too baggy—giving it a clean, relaxed look that works great for both casual outings and slightly nicer dinners by the beach.
Overall, this shirt checks all the boxes: comfortable, breathable, stylish, and ideal for vacation wear. Already grabbing a few more colors

Slim but comfortable sizing looks upscale, wrinkle free from the dryer
Size: Medium, Color: Denim Blue
This is a very nice upscale looking shirt. It has great styling that is not over-sized. My husband normally wears a medium or large depending on the cut/style. He got a medium in this size and it is a perfect, comfortable fit. It arrived with some creases in the material from being folded in the packaging but it came out beautifully from the dryer. I'm happy he has a casual but nice shirt to wear when he takes me out to dinner!
