Featuring an 85.50 mm bore diameter and a 28.87 mm compression height, these pistons are purpose-built for high-output turbocharged 4G63 applications. The 0.8661 in. (22 mm) pin diameter provides a robust wrist pin interface capable of handling elevated cylinder pressures from forced induction builds.

Key Features:

  • Bore Diameter: 85.50 mm
  • Compression Height: 28.87 mm (1.137 in.)
  • Pin Diameter: 0.8661 in. (22 mm)
  • Material: 2618 high-strength forged aluminum alloy
  • ArmorGlide® Skirt Coating — seizure resistant, friction-reducing, and promotes quieter operation
  • Fully machined crown features and precision ring grooves
  • Anti-detonation groove and additional ring seal improving features
  • Forced pin oiling for enhanced lubrication under extreme conditions
  • Manufactured in the USA at Wiseco's Mentor, Ohio facility

The Wiseco K667M855 piston set is a direct solution for builders seeking a reliable, high-performance upgrade for the 4G63 engine platform. Whether rebuilding for street performance or all-out competition, these Professional Series pistons are built to withstand heavy to severe-duty use.

1. The URL does NOT show as being secure for CC entry information. 2. I did not find any assurance my phone number won't be shared. 3. A page stating my personal information won't be shared would be great.

My order was correct and fit as required. Shipment took a little longer than I would have liked but satisfactory but the tracking not so much. Overall good experience and will shop with THMotorsports again !

Fast shipping. Good communication via email. Everything as expected. (Not always as common as it should be these days.) Thanks.

I had no problems at all with this site

I am really liking the West System Epoxy products.
