Product Details

The Sealed Power E925K40 is a premium plasma-moly engine piston ring set designed as a direct-fit replacement for 6-cylinder engines. Manufactured to ISO and QS certified standards, this set is engineered to meet or exceed OEM specifications and is built to handle the demands of both daily drivers and rebuilt engines.

The top compression rings feature a plasma-molybdenum (plasma-moly) facing — a heat-resistant, porous coating with excellent oil retention properties that promotes rapid break-in and consistent contact with the cylinder wall. The second compression ring uses a cast iron facing for added durability, while the oil control rings are constructed from stainless steel to help minimize oil consumption and resist corrosion.

Key Features:

  • Plasma-moly coated top compression rings for fast break-in and scuff resistance
  • Cast iron second ring for superior long-term durability
  • Stainless steel oil control rings to reduce oil consumption
  • Exacting tolerances — meets or exceeds OEM specifications
  • Excellent resistance to ring face flaking due to improved plasma-moly bond strength
  • Reduced friction for improved engine efficiency
  • High melting point moly coating for extreme heat resistance
  • Suitable for street use, marine use, and non-file-fit racing applications
  • Manufactured under ISO and QS certified quality processes
  • Made in the USA

This set is sized at a +0.040 in. oversize bore, making it ideal for engines that have been bored or honed during a rebuild. Cross-reference part numbers include Clevite 41870CP040 and Hastings Piston Rings 2M4815040.

Ordered monroe struts and shocks best price I could find. Will order again from Autoplicity when I need something else for one of my cars.

Great price, and quick processing of my order. Will use again.

Excellent Service! Product shipped out the day after being processed and was sent via overnight delivery. Autoplicity also offered the lowest cost available for the product online.

By the time you add in shipping, even the "Rock" can't compare! Thanks!

After shopping around for a specific cargo carrier, Autoplicity had the best total price by over $50 and great ratings, so I gave them a try. I received the SportRack Aero XL - A90275 last Thursday and am VERY impressed with their price and service. The cargo carrier arrived quickly (ordered Sat, rec'd Thurs) and in fine shape. I will recommend Autoplicity to my friends, and plan to shop with them for my future automotive needs.

Super easy + best price on the web. Very pleased am I.

Excellent--- fast response and shipping.

Ordered a K&N cold air intake for my 2010 ford focus in hopes to add a little horsepower and mpg. Well, autoplicity has great customer service and my part arrived exactly when it was supposed to. Very pleased with autoplicity, will be going back for my future purchases, you can't beat their prices and service!
