Precision Engine Assembly with ARP 86.5mm Ring Compressor

Achieve professional-grade engine builds with the ARP 86.5mm Tapered Piston Ring Compressor. Designed for master engine builders and performance enthusiasts, this tool eliminates the frustration of piston installation. The CNC-machined, tapered design ensures that your piston rings are compressed smoothly and evenly, preventing damage to the rings or cylinder walls during insertion.

Key Features and Benefits

  • Precision Fit: Specifically engineered for 86.5mm bore applications.
  • Tapered Entry: Allows for a seamless transition of the piston into the cylinder bore.
  • Durable Construction: Manufactured from high-strength billet aluminum with a hard-anodized finish for long-lasting wear resistance.
  • Damage Prevention: Eliminates the risk of snagging or breaking rings during assembly.

Using a high-quality ring compressor is critical for maintaining proper ring seal and optimal compression ratios. Unlike universal band-style compressors, this ARP tapered tool provides a consistent, uniform squeeze around the entire circumference of the piston. Whether you are performing a routine rebuild or a high-performance engine upgrade, this tool is an essential addition to your workshop. Experience the difference in quality and ease of use that only ARP engineering can provide. For all your high-performance automotive needs, trust the selection available at GGCRACING.
