ARP 86.0mm Ring Compressor for Honda K20 Nissan SR20DET

This ARP 86.0mm Ring Compressor is a precision tool for installing pistons in 86mm bore engines found in Honda K20-equipped Civics, RSX, Type R and Nissan SR20DET 240SX. It applies even pressure to compress rings smoothly during cylinder insertion, preventing damage and ensuring leak-free seals for high-performance rebuilds. Built tough for multiple uses by engine builders.

Key Features

  • Exact 86.0mm Sizing: Matches Honda K20 and Nissan SR20DET bores for secure ring compression without slippage or distortion
  • Durable Construction: High-strength materials resist cracking and wear through repeated high-heat engine builds
  • Tapered Design: Gradually compresses rings as piston enters bore, reducing risk of ring breakage or misalignment
  • Application-Specific Engineering: Developed by ARP for popular performance engines, includes matched components for quick setup
  • Easy Identification: Clear size markings speed up tool selection in busy shops or garages

Product Notes

  • Inspect cylinder bores for cleanliness and roundness before use
  • Store in dry conditions to maintain shape and performance
  • Ships in compact box, weight 0.80 lbs with protective padding

Installation Notes

  • Professional installation recommended.
  • Lubricate rings and bore lightly before compressing and inserting piston
  • Compatible with stock and aftermarket pistons in listed 86mm applications
