Precision engine assembly requires tools that protect your components during critical steps. The ARP 900-2125 Tapered Piston Ring Compressor is CNC-machined from 6061-T6 aluminum billet and features a specific radius for its designated bore size. Unlike universal adjustable band-style compressors, this fixed-diameter tool provides a smooth, tapered transition that ensures rings are compressed evenly into the cylinder without the risk of snagging or breakage.

  • Bore Size: 4.2125 inches
  • Material: CNC-machined 6061-T6 aluminum billet
  • Finish: Type III hard-anodized for long-term durability and wear resistance
  • Design: Precision-tapered bore with internal radius for seamless piston installation
  • Manufacturer Part Number: 900-2125
