Product Details

The MAHLE Perfect Circle S41517.020 is a .020" oversize piston ring set engineered for precise fitment during engine rebuilds and overhaul applications. Manufactured under the trusted Perfect Circle brand — a division of MAHLE, one of the world's leading engine component suppliers — this ring set is built to restore proper compression, oil control, and sealing performance to worn or bored engines.

MAHLE Perfect Circle piston ring sets are produced to strict OEM-equivalent tolerances, ensuring reliable performance and longevity. The .020" oversize designation makes this set compatible with cylinder bores that have been machined 0.020" over the standard factory diameter, a common specification in professional engine rebuilding.

Key Features:

  • Oversize: .020" (+0.020" overbore) for use in machined/bored cylinders
  • Brand: MAHLE Perfect Circle — an OEM-trusted name in engine components
  • Function: Restores compression, minimizes oil consumption, and improves engine sealing
  • Construction: Manufactured to precise dimensional tolerances for proper ring end gap and tension
  • Application: Designed for engine rebuild and overhaul use
  • OEM-equivalent quality: Meets or exceeds original equipment specifications

MAHLE Perfect Circle piston rings are a go-to choice for professional engine builders and rebuilders who demand consistent quality. Always verify cylinder bore measurement prior to installation to confirm .020" oversize fitment is correct for your application.

thank u

Easy checkout. I'll leave further comment when it arrives.

All parts I ordered were in stock and arrived 4 days after I ordered them! One item was even 46% less than any other place online. I'm super pleased.

I'm unsure how it's connected to my amazon account but that made it faster.

Like the free shipping on the fuel tank!
