FAQs
Do these pistons include rings, pins, and clips?Yes - the PDM-360.020 set includes matched rings, wrist pins, and pin locks for all eight cylinders.
Are the crowns and skirts coated?Yes - thermal barrier crown coating and low-friction skirt coating help manage heat and reduce scuffing in heavy-load use.
What ring set should I use for .020 over?Use a .020 ring set matched to your engine family (e.g., LB7 vs. LML). You can browse ring options in our Duramax Pistons & Rings category.
Should I upgrade to head studs when installing pistons?We highly recommend head studs on any performance/tow build. See ARP 230-4201.
Is machine work required?Yes, .020" oversize pistons require precision boring and honing with torque plates. Always verify clearances for your use case.
