The FX400 System uses the Power Plus I Pressure Plate with a custom, extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 4 or 6 wing (paddle) configuration, with the 4-wing being the more aggressive setup (please specify which type you prefer). The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more streetable than solid or rigid designs. This disc is designed for long life, outstanding holding capacity, and rapid heat dissipation.

The clutch for aggressive drivers. This is the perfect road-racing application. FX400 utilizes a 4 or 6 puck ceramic sprung disc complemented by a bulletproof hub assembly. It is designed for cars with significant power upgrades. Engagement is hard and quick.

Warning: Due to the solid (no Marcel) friction rivet design, the FX400 disc engages very quickly and may chatter slightly in first and reverse. To help alleviate this problem, we only use premium ceramic friction material.

Sprung Ceramic System. 170% increase in holding capacity. Ultra Heavy Duty street and/or Racing

Good for receding gums
Size: 4 Ounce (Pack of 1)
I use this Boka toothpaste daily and it is super sensitive on my receding gums. It has a subtle flavor, and isn't too strong. Highly recommend if you have sensitive teeth.

Makes my sensitive teeth have a magical shield
Size: 4 Ounce (Pack of 1)
I've been using the Boku sensitive toothpaste twice a day for almost 2 months now and it's definitely improved my tooth sensitivity since I first started. I used to have to be extra careful about what I ate or drank, specially while out in the cold because the pain I felt was unbearable. Now it's like a magical coating is protecting them because it's barely noticable anymore. I also really like that it doesn't taste bad, and it leaves my teeth looking a few shades lighter and my breath stays pretty fresh for a decent amount of time after using. The only thing I would change is the consistency because it's a lil thin and kinda flings everywhere on my spin brush but that isn't enough to make me dislike it.

Works amazing! Worth the price!
Size: 4 Ounce (Pack of 1)
I absolutely love this toothpaste, I read an article where you can 100% use it with your Sensodyne or Colgate sensitivity toothpaste to get the sensitivity benefit from that as well as the remineralizing from this toothpaste. I didn’t notice a texture difference at all, the taste was good, I will definitely be buying this again. I used it with David’s coconut oil pulling and my teeth feel amazing, no sensitivity to cold or hot anymore! Buy it yesterday you won’t be disappointed
