The NS1-HDG6 kit pairs ACT's most popular Heavy Duty pressure plate with a 6-pad, spring-centered race disc, sized for the Nissan SR20DET 2.0L turbo. This is a common swap into the S13/S14-chassis 240SX and matches the factory clutch dimensions used in the JDM Nissan Silvia and 180SX. The Heavy Duty pressure plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and extend clutch life; every diaphragm goes through a four-stage heat-treating process, and cover stampings are precision-made for rigidity and consistency. The 6-pad, spring-centered race disc damps torsional vibration and resists failure under hard use, with wraparound spring windows and thicker retainer stampings for added strength. Engagement is firmer than a street disc, but shifts are quicker, and the larger pad design helps the disc absorb more heat.

Vehicle Applications
NS1-HDG6 is built to the SR20DET 2.0L turbo bellhousing and spline specification rather than a single OE vehicle listing. It matches the factory-fitment SR20DET clutch used in the JDM Nissan Silvia (S13/S14) and 180SX (S13), and is a common fitment for SR20DET-swapped Nissan 240SX (S13/S14) chassis in North America. Confirm bellhousing and spline match before ordering if your swap uses a non-factory adapter or transmission.
FAQ
Does this kit fit a stock 240SX?
Not directly. A stock USDM 240SX did not come with the SR20DET; this kit matches the SR20DET clutch specification used by the JDM Silvia/180SX and is a common fitment for SR20DET-swapped 240SX chassis.
What does HD/Race Sprung 6 Pad mean?
It refers to the pairing in this kit: an ACT Heavy Duty pressure plate matched to a 6-pad, spring-centered race disc for higher clamp load and quicker shifting than a stock setup.
Is this kit streetable?
It can be driven on the street, but engagement is firmer than a street disc; it suits drivers who want faster shifting and more heat capacity and can tolerate more driveline feel.
What's included in the kit?
The kit includes the ACT Heavy Duty pressure plate and the 6-pad, spring-centered race disc sized for the SR20DET.
