Product Details

The MAHLE 3021069 is a second compression piston ring designed for 8-cylinder engines with a 4.350-inch bore. Constructed from cast iron with a reverse-twist taper-faced profile and 1/16-inch (0.0625 in.) axial thickness, this ring delivers reliable oil control and combustion sealing performance in high-demand applications.

The second ring serves a dual role in engine operation: it is primarily responsible for controlling oil migration past the piston, handling up to 80% of oil control duties, while also contributing to compression sealing. MAHLE's precision-ground ring flanks ensure consistent ring-to-groove contact and optimal sealing throughout the engine's operating range.

Key Specifications:

  • Ring Position: Second (Lower Compression) Ring
  • Material: Cast Iron
  • Bore Size: 4.350 in.
  • Axial Thickness: 1/16 in. (0.0625 in.)
  • Engine Configuration: 8-Cylinder
  • Ring Profile: Reverse-twist, taper-faced

MAHLE is the world's largest piston ring manufacturer, with over a century of experience supplying rings for both original equipment and aftermarket applications. This second ring is sold individually and is engineered to MAHLE's exacting OE-grade tolerances, making it a trusted choice for engine rebuilders and performance enthusiasts alike.

REALLY HARD ITEM TO FIND VERY SATISFIED

So far, so good. Easy to purchase. Good fit and speedy delivery.

it was one of the most easiest sites to use and the order shipped really quick. will buy from again.

fast and great pricing

Best price.

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.

good price

Quick and easy, lowest price available, plus free shipping!

very low prices

Shipping it a little high.. I think offering different shipping methods for lower prices would be nice. Other that that the transaction went as smoothly as possible!
