ACT HD/Race Sprung 6 Pad Kit Toyota Crown | Hi-Lux 1967-1971

If you're looking to upgrade your clutch setup, the ACT HD/Race Sprung 6 Pad Kit (T41-HDG6) is a solid choice that I can personally vouch for. This kit packs a punch with ACT's heavy-duty pressure plate, which is known for its killer performance and durability. They’ve really nailed it with the diaphragm design—it's built to increase clamp load while minimizing deflection, so you can expect a longer clutch life even under some serious stress.

What I love about this kit is the four-stage heat-treating process that the diaphragms go through. It’s not just marketing fluff; it genuinely enhances performance and reliability. The precision cover stampings on the pressure plate add a level of rigidity that you can feel when you’re driving. It's all about that confidence when you’re pushing your ride to the limit.

Now, let’s talk about the 6-pad, spring-centered race disc. This thing is a beast. It dampens torsional vibrations and holds up well even in harsh conditions. Sure, the engagement is a bit harsher than what you might be used to, but that’s part of the deal when you want faster shifts. It’s designed for larger clutch sizes, which helps absorb more heat, making it ideal for high horsepower street or race applications.

Installation is straightforward, but if you need a hand, you can check out the installation instructions here.

Here’s what you can expect with this kit:

  • Light to moderate pedal effort, with an aggressive engagement that might cause a bit of gear rattle—nothing too crazy, though.
  • Moderate friction life, thanks to that exclusive diaphragm design, prolonging the lifespan of your clutch.
  • Carefully engineered and balanced, using select ceramic friction materials for high heat tolerance.
  • Great for high horsepower setups, whether you’re hitting the streets or the track.
  • Every unit is 100% clamp load tested and dynamically balanced, ensuring smooth operation at high RPMs.
