Piston Ring Compressor
Ring Compressor 81.5 mm
ARP’s ring compressors are CNC Machined from 6061-T6 billet and feature a true radius for each different bore diameter. What’s more, they are relieved for wire O-rings. Anodizing is utilized to protect the material, and the bore size is engraved for easy identification.
The true radius design is far superior to the common tapered units, and used by professional engine builders. This is the best piston ring compressor on the market today.
