Product Details

The Wiseco 9425XX is a replacement piston ring set designed specifically for Wiseco pistons with a 94.25mm (3.711") bore. Engineered to Wiseco's exact specifications, this three-ring set delivers superior cylinder sealing, reduced friction, and efficient heat transfer for high-performance 4-stroke engines.

Ring Set Specifications:

  • Top Ring: 1.00mm (.039") stainless steel, gas-nitrided, barrel-faced design for maximum compression sealing and durability
  • Second Ring: 1.20mm (.047") cast iron, phosphate-coated, taper-faced under-hook style for optimized oil scraping and sealing
  • Oil Control Ring: 2.80mm (.110") 3-piece assembly featuring gas-nitrided rails and a stainless steel flex-vent spacer for precise oil control

Key Features:

  • Manufactured to Wiseco's precise tolerances for optimal fit with Wiseco pistons
  • Gas-nitrided top ring provides exceptional wear resistance and long service life
  • Part of Wiseco's popular XX-series ring sets, covering bore sizes from 75–100mm (2.953"–3.937")
  • One ring set services a single piston
  • Designed and tested for race-ready performance across motorcycle, automotive, ATV, snowmobile, marine, and powersports applications

Wiseco piston rings are only compatible with Wiseco pistons. Each set provides rings for one piston. For multi-cylinder engines, order one set per cylinder.
