The true-radius design of ARP tapered ring compressors is far superior to conventional tapered devices, and they're widely acclaimed by professional engine builders. Dozens of sizes are available for both standard and metric applications.

Type 3 anodizing is used for long life, and the bore size is prominently engraved in 3/4˝ high numbers for easy identification. Standard stocking sizes from 3.552˝ to 4.750˝ (SAE) and 75mm to 95.5mm (metric). The true radius design is far superior to conventional “tapered” devices, and widely acclaimed by professional engine builders! This is truly the very best piston ring compressor on the market today.
