These are the pistons and rings we install in our Stage 1, Stage 2 and Stage 2.5 engines. We have been using these for 15+ years without issues. We have our kits made for us with Hastings Moly rings.
Each set is inspected to insure all pistons are the same weight, consistant size and correct taper.
They include new pistons, wrist pins, pin clips and a full set of Hastings Moly rings.
Your machine shop will need these before they bore your block and they'll need the wrist pins to resize your rod bushings, so plan ahead.
Available in standard, .50mm (.020”), 1.00mm (.040”) and for 22R/22RE 1.5mm (.060”)
(.060" not available in cast for 22RTE, see our forged piston options)
