(HPF)Piston Set with Rings (QR25) 9.5-1 Comp (Turbo an NA)

2JR produced turbo pistons with hastings racing ring set. Hard anodized piston domes to resist detonation. Thicker ring lands to prevent cracking. Moly coating on the skirts to lubricate piston walls. 9.5-1 Comp with the best anti-detonation quench pads on the piston tops. Good for up to 450whp.
