FAQ

FCC denotes a competition-oriented piston spec designed for higher cylinder pressures and sustained heat vs. stock/CC versions intended for OE-like use.

Yes. The kit includes matched rings, wrist pins, and clips to pair with your .040" overbore.

Studs are strongly recommended for boosted/competition builds to maintain clamp load and sealing. See the ARP kit linked above.

Standard thickness (HS4068) suits most builds; thicker options like HS4068A can help target quench/compression with decked blocks or larger lift cams.
