Product Details

The MAHLE 3030746EB is a high-quality plain ring set designed for precision engine rebuilds and performance applications. This CP20 bulk oil ring expander features a 4.390-inch bore diameter with a 3/16-inch width, engineered to provide optimal tension and seal integrity for oil control rings.

Key Features:

  • Precision-manufactured oil ring expander for consistent ring tension
  • 4.390-inch bore diameter fits large displacement V8 and performance engines
  • 3/16-inch width provides robust support for oil control rings
  • CP20 specification ensures proper radial pressure distribution
  • Plain design allows for bulk packaging and cost-effective engine building
  • Manufactured by MAHLE, a trusted OEM supplier to major automotive manufacturers

This oil ring expander is a critical component in maintaining proper oil control and preventing excessive oil consumption. The precise engineering ensures even pressure distribution around the cylinder bore, helping to maintain optimal compression and reduce blow-by. Ideal for professional engine builders and serious DIY enthusiasts working on high-performance or large-displacement engines.

Found what I needed at a fair price. There was never an email confirming that my purchase was shipped so I had no way to track it or any idea when it would arrive. After I received my order I received an email stating that my purchase had been shipped but the information of when this took place was not included. Product was great, got it within a week, but communication to purchaser is lacking.

Easy sale - nice touch being able to use Amazon to pay - quick ship - well packaged

Great price looking forward to getting item

Service was great. The Diamond Eye exhaust is high quality. 100% satisfied.

I had just bought a body lift and spacer for truck, and sure enough it all came in a timely fashion. This site is a great one to check out if you need any parts. Easy access, quick processing, I believe this is the,site ill use fot now on.

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!
