Product Details

The MAHLE Original 4007 is a premium stainless steel engine piston ring set engineered to OE specifications. MAHLE piston rings are designed to reduce friction and ring mass while minimizing engine oil consumption and delivering extended service life — making them a trusted choice for professional engine builders and automotive technicians alike.

Key Features:

  • Installer-Friendly Design: Pre-lapped rings seat immediately, virtually eliminating break-in time
  • Optimized Materials & Coatings: Ring materials, coatings, and tension are all matched to each application for reduced friction and long-term durability
  • Barrel-Faced Compression Rings: Provides more efficient compression with a CNC-controlled gap chamfer to minimize blow-by
  • Reverse Twist Intermediate Rings: Improves groove side sealing with taper race machining for enhanced cylinder wall contact
  • CP-20 Oil Ring Assemblies: Feature an exclusive 20-degree ear angle for superior side sealing against the cylinder wall, plus a chemically polished expander for enhanced oil drain-back
  • Stainless Steel Construction: Premium-grade stainless steel rings deliver durability and resistance to wear

MAHLE Original piston ring sets are built to the same exacting standards as original equipment components, making the 4007 an ideal replacement for engine rebuilds and overhauls requiring precise fitment and long-lasting performance.

Very quick and simple

Found the items right away and it was a great price.

very happy

Great Item(Husky floor mats) it was the cheapest price I could find and item arrived new in box no damage. It also arrived in a very timley manner(3days)

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 was asked if the product I was purchasing was needed by a specific date in order to complete a project on time. Autoplicity responded and had the product to me a day earlier than I asked for without additional cost to me. I will order from them again.

Fiest time here if it works I ll be back often

Found the best price at Autoplicity on my cold air intake. Quick turn-around time and inexpensive shipping. I'll definitely be back.

Great price and easy ordering. Cant wait for my nudge bar.

I ordered an AEM intake from Autoplicity because they had the best prices but it was on backorder from AEM. Autoplicity emailed me to let me know right away and sent me a confirmation when it was back in stock. I'll be shopping here again!

Very direct and effective. No BS.
