Upgrade Your Clutch with the ACT ZT2-XTR4 Kit

If you're a Mazda B-Series owner from 1987-1988 looking to enhance your vehicle's performance, the Advanced Clutch Technology (ACT) ZT2-XTR4 4 Pad Kit is a robust upgrade designed specifically for the demands of spirited driving and track days. This kit features an Xtreme pressure plate, engineered to deliver increased clamp load and reduced deflection, ensuring your clutch performs at its best under pressure.

Performance-Driven Design

The heart of the ZT2-XTR4 is its exclusive diaphragm design, which not only maximizes clutch life but also provides a high level of reliability during aggressive driving. Each diaphragm goes through a rigorous four-stage heat treatment process, resulting in unparalleled performance that you can count on during high-stress situations.

Race-Proven Components

• The 4-pad rigid race disc is constructed from high-quality ceramic friction materials, providing excellent heat tolerance and consistent performance.
• With a lightweight and rigid design, shifts become quicker and smoother, making it ideal for those who value performance and responsiveness.
• Note that while the engagement is more aggressive, it translates to faster shifts—a necessary trade-off for serious racers.
