Product Details

The MAHLE 3021339B is a high-performance piston ring set engineered for precision engine applications requiring a 3.5531-inch bore diameter. This professional-grade ring set features a steel Napier-style second ring design, combining durability with optimal oil control and combustion sealing.

Key Specifications:

  • Bore diameter: 3.5531 inches
  • Ring thickness: 1.2mm
  • Radial wall thickness: 0.135 inches
  • Steel Napier second ring configuration for enhanced oil control
  • Plain ring set design
  • Manufactured to MAHLE OE specifications

MAHLE performance ring sets are precision-manufactured using advanced materials and coatings to provide superior wear resistance, reduced friction, and consistent compression throughout the engine's operating range. The Napier ring design features a hooked profile on the second compression ring that effectively scrapes oil while maintaining proper cylinder wall lubrication. Ideal for performance rebuilds, racing applications, or high-quality engine restoration projects.

Easy enough until it came to payment. "Check out with Amazon, it'll be faster." It wasn't.

so far so good

Quick comment

It would be nice to have a time quote for how long shipping will take

Was GREAT!!!!

Found exactly what I was looking for.

Always good and quick service.

great site

I like this site. Large variety to choose from.

So far, so good.

Good price, the only decent place I could find this part online.

Best price for the particular part I was ordering. Their staff/customer service is very helpful and polite, but unfortunately their shipping times are lacking. Before ordering on Monday, I called to verify the item was in stock, and asked what shipping method I would need to ensure it would arrive before Saturday. I was told 2nd Day Air. I ordered that same day (around 1pm). The package wasn't shipped until Wednesday evening, AFTER I called and inquired a to why it hasn't moved. What really upset me though was that the package ended up being shipped UPS Ground anyways, to arrive here the very next day. Long story short, I shouldn't have had to pay the extra $20+.
