ARP Tapered Piston Ring Compressor - 88.0mm

The ARP Tapered Piston Ring Compressor guides pistons into the bore with the rings fitted, its tapered true-radius bore squeezing the rings into their lands as the piston slides through. It is CNC-machined from 6061-T6 billet aluminum, Type 3 black anodized, with the bore size engraved. This is the 88.0mm size.
