Description: The ZX4-XTG4 kit is tailored for the most demanding drivers, featuring an Xtreme pressure plate renowned for its exceptional performance. ACT Xtreme pressure plates utilize an exclusive diaphragm design to enhance clamp load, reduce deflection, and maximize clutch life. Through a four-stage heat-treating process, all diaphragms are meticulously treated for unparalleled performance. Precision cover stampings ensure rigidity and consistency, providing a reliable driving experience.

This kit includes ACT's 4-pad spring-centered race disc, designed with a spring-center construction to effectively dampen torsional vibrations and resist failure even under harsh conditions. ACT spring retainers are engineered with wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and enhance strength and reliability. Although engagement may be harsher with the 4-pad spring-centered race disc, shifting is notably faster, making it ideal for high-horsepower street or race applications. Moreover, this disc is well-suited for smaller disc sizes in smaller engines.

Key Characteristics:

  • Feel: Moderate to heavy pedal effort, aggressive engagement, OE to mild gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, using select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for high horsepower street or race use, delivering exceptional performance and reliability.

ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.

Vehicle Fitment: Compatible with various Mazda models, including the 2006-2013 Mazda 3 Mazdaspeed and the 2006-2007 Mazda 6 Mazdaspeed equipped with the 2.3 L4 GAS FI 2260cc | DOHC engine.

Best pillow I've ever owned
Color: Cut-out White, Size: Queen
While the pillow looks anemic when it first comes out of its packaging, it puffs/firms up beautifully after time in the dryer. I haven't had any odor issues. I'm mostly a side sleeper and at first I thought there wasn't enough of the extra fill, so I put it all in. I've ended up needing to take at least half back out to keep my head at the correct angle. While this can fit in a standard pillow case, it just barely fits and keeps coming out - at least at my fill level. Queen pillow cases are much better. This is so much more comfortable than any of my previous pillows. I don't need to stack multiple pillows to get the right support. I'm no longer waking up with neck or shoulder or arm pain. I'm recommending it to pretty much everyone and I've purchased a second pillow to keep at my parents for when I visit!

So nice your wife will steal it for herself
Color: Original White, Size: Queen
This, this is the god of all pillows I’ve ever purchased. It’s the perfect balance of firm and soft and it’s easily adjustable using the added filler. I’m a side sleeper so having a primary pillow is a must. Combined with a decent secondary pillow this one provides a perfect amount of support. This pillow is so nice, my wife ‘borrowed it’.

Favorite pillow!!
Color: Original White, Size: Queen
Absolutely love this pillow! Bought my husband one a year ago after he was waking up with neck pain. Just recently bought myself one, we both love them! Very comfy and comes with a bag of extra foam to add/remove from the pillow. The zipper on the side of the pillow cover is hidden but durable. We take it with us wherever we go, and always sleep so good.

Super comfortable!!!!
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
They are super soft and large; they come vacuum-sealed and expand very quickly. They aren't heavy, and they are incredible for sleeping and watching TV in bed.
