ACT HD/Perf Street Sprung Kit Nissan | Infiniti 1985-2001 - NM1-HDSS

ACT NM1-HDSS Heavy Duty Clutch Kit

If you're looking to enhance your driving experience in your 1996-1999 Infiniti I30 or 1985-2001 Nissan Maxima, the ACT NM1-HDSS Heavy Duty Clutch Kit is a solid choice for both street and spirited driving. This kit combines ACT's most popular Heavy Duty pressure plate with a performance street disc, ensuring you get the best of both worlds—reliability and performance.

Why Choose the NM1-HDSS?

The NM1-HDSS features an exclusive diaphragm design that significantly increases clamp load while reducing deflection, which ultimately extends the life of your clutch. Each diaphragm undergoes a rigorous four-stage heat-treating process, giving you the confidence that it can handle the heat of aggressive driving without compromising performance.
