Product Details

The ARP 901-9050 is a precision-engineered piston ring compressor designed for professional engine builders and serious enthusiasts. CNC-machined from 6061-T6 billet aluminum tube material, this tool features a true radius design that matches the exact bore diameter for superior piston installation compared to conventional tapered compressors.

Key Features:

  • CNC-machined from 6061-T6 billet aluminum for durability and precision
  • True radius design provides even compression around the entire piston ring pack
  • Relieved bottom edge accommodates wire O-rings without interference
  • Type 3 hard anodized finish for long-lasting wear resistance
  • Bore size prominently engraved in 3/4-inch high numbers for easy identification
  • Professional-grade tool widely acclaimed by engine builders

Unlike tapered ring compressors that can cause uneven compression and potential ring damage, the ARP true radius design ensures smooth, consistent installation every time. The precision machining and hard anodized finish make this compressor a lifetime tool for your engine building arsenal.
