Description HKS 21005-AN018 Piston Ring Set d-86.5 (6 pcs)

The HKS 21005-AN018 piston ring set (diameter 86.5 mm, 6 pieces) is designed to improve sealing performance, reduce friction, and enhance engine durability. Incorporating the latest advancements in piston ring technology, this renewed specification addresses the evolving demands of modern internal combustion engines.

Features: Top Ring

  • Reduced blow-by gas through a 27% smaller gas passage area at room temperature
  • High thermal expansion coefficient material reduces joint gap by approx. 88% at high temperature
  • Improved thermal conductivity (+37% vs. conventional) for better cooling and reduced groove wear
  • Lower ring tension decreases friction
  • Revised surface treatment and optimized film thickness extend service life

Features: 2ND Ring

  • Enlarged joint gap (~25%) reduces second land pressure and stabilizes top ring
  • Prevents top ring fluttering, enhancing sealing power
  • Approx. 18% lower ring tension reduces friction compared to conventional design

Features: Oil Ring

  • Three-piece oil ring design replaces conventional two-piece type
  • Approx. 10% lower ring tension significantly reduces friction
  • Maintains effective oil scraping function without increased oil consumption
