FAQ
Are these truly “drop-in” pistons?Yes—this is a standard-bore set machined to OEM spec and includes rings, pins, and clips. Always measure and set proper clearances during assembly.
Do these pistons have valve reliefs?This PDM-360STD set is de-lipped and supplied without valve reliefs. If you need fly-cut valve reliefs for high-lift cams, see the forged PDM-362 series or fly-cut options in oversizes.
What coatings are used?A thermal barrier coating is applied to the crown and a ceramic friction-reducing coating is applied to the skirts to handle heat and load under heavy use.
Which supporting mods are most important?ARP head studs, correct head gaskets, and (for LML trucks) a CP3 conversion when increasing fueling. Quality tuning and fuel filtration are also key.
