Product Details

The MAHLE 4140MS-112 is a premium file-fit piston ring set engineered for precision engine builds requiring exact ring end-gap specification. Designed for a 4.135-inch bore with a +0.005-inch oversize (4.140-inch actual bore diameter), this three-piece ring set delivers optimal compression sealing and oil control in high-performance and racing applications.

Ring Configuration:

  • Top compression ring: 1.0mm (0.039-inch) thickness
  • Second compression ring: 1.0mm (0.039-inch) thickness
  • Oil control ring: 2.0mm (0.079-inch) thickness

Key Features:

  • File-fit design allows custom end-gap adjustment for precise piston-to-ring clearance
  • Manufactured to MAHLE's OEM quality standards with premium materials
  • Low-tension design reduces friction for improved horsepower and fuel efficiency
  • Ideal for performance rebuilds, custom engine builds, and racing applications
  • Compatible with 4.135-inch +0.005-inch overbore pistons

MAHLE piston rings are precision-engineered to provide superior sealing, reduced blow-by, and extended engine life. The file-fit feature makes these rings essential for engine builders who demand exact tolerances and optimal performance from their builds.

Quick experience. Good prices. A little concerned that the order didn't display my exact vehicle for verification of fit purposes.

Fast and inexpensive!!

i like

Absolutely satisfied and will order more products for my vehicle from Autoplicity! !

great service

It has been good. The only confusing thing was whether the different anco model blades were winter or not (I want winter). E.g. c26-oe and a26-oe versus 3026oe.

Good so far. Easy registration and login. Nice line of products.
