FAQ
Are these pistons a direct drop-in?The set includes rings, pins, and clips, but a .020" overbore and precise measurements are required for correct clearances.
What’s the advantage of the FCC (coated, fly-cut) version?Thermal crown and skirt coatings improve heat management and reduce friction, while fly-cut reliefs add piston-to-valve clearance for high-lift cams.
Do I need head studs with these pistons?Head studs are strongly recommended on any performance build to maintain MLS head gasket seal under higher boost and cylinder pressure.
Which head set should I choose?Choose an HS54774 series head set that matches your needs (with or without valve cover gasket) for 2007.5–2018 6.7L Cummins.
