Product Details

The MAHLE Original S42104.040 is a premium plasma-moly piston ring set engineered for a 4.150-inch (105.41mm) bore on V8 diesel applications. Sold as a single-cylinder set, this ring package delivers OE-grade quality with features designed to reduce friction, minimize oil consumption, and extend engine service life.

Key Features:

  • Plasma-Moly Top Compression Ring — 3.14mm axial height with a barrel-faced contact surface for efficient compression sealing and a CNC-controlled gap chamfer to minimize blow-by
  • Intermediate Compression Ring — 2.5mm axial height featuring a reverse-twist design for superior groove side sealing and taper-race machining for enhanced cylinder wall contact
  • CP-20 Oil Control Ring Assembly — 3.45mm axial height with an exclusive 20-degree ear angle for optimal side sealing against the cylinder wall; chemically polished expander promotes efficient oil drain-back
  • Pre-Lapped Finish — Rings seat immediately upon installation, virtually eliminating traditional break-in time
  • Optimized Ring Tension — Materials, coatings, and tension specifications are matched to the application for reduced friction and long service life
  • Single Cylinder Set — Order quantity of 8 for a complete V8 engine set
  • UPC: 027067820341

Had the best price on the web for the item ordered. Fast processing and shipping. Only took 3 days total to receive my order.

Easy transaction

quick and easy! had no problems at all

most competitive price i've been able to find for the ebc redstuff. with the shipping price it is still hard to argue against such prices, along with a guild letting me know these brakes will fit on my car. +1

same part Firestone quoted me190 for....this was a huge savings.

SHOPPED THE PRICE EVERYWHERE. BEST DEAL ON THE WEB!

Quick shipping, good communication, low price, would purchase again from this company.

The site was easy to navigate and find what I needed. The price was the best I could find for the Husky weatherbeater floor mats that I needed for my car. Shipping was fast. Can't wait to have them in my car.

Perfect i broke one ring while installing, this set is the exact one.
