Product Details

The MAHLE 40787.020 is an oversize engine piston ring set engineered to OEM specifications for use during engine rebuilds and overhauls. The .020" (0.50mm) oversize designation makes this set the standard first-oversize choice when cylinder bores have been honed or bored to restore proper wall geometry and clearance tolerances.

MAHLE Original piston rings are manufactured to strict dimensional and metallurgical standards, ensuring proper ring tension, seal integrity, and long-term durability. Each ring is precision-ground to deliver consistent gap tolerances, supporting optimal compression, minimized oil consumption, and efficient combustion.

Key Features:

  • Oversize: +0.020" (0.50mm) over standard bore diameter
  • Manufactured to OEM fit, form, and function specifications
  • Precision-ground ring faces for consistent sealing and break-in performance
  • Engineered for proper ring tension and gap tolerances
  • Supports reduced oil consumption and improved compression retention
  • Complete set includes compression rings and oil control rings for all cylinders
  • Made by MAHLE, a globally recognized OEM supplier to major engine manufacturers

MAHLE Original piston ring sets are a trusted choice for professional engine rebuilders and performance shops requiring reliable, specification-grade components. The 40787.020 set is designed as a direct replacement for worn or damaged rings in applications requiring a first oversize bore.

Autoplicity had by far the best price I found for the part I needed. My order shipped promptly. I recommend them to all.

So far great.

I ordered a new clutch on June 12, and the item shipped the same day. Had the item on time as expected. They also beat all other retailers prices by a significant amount. Their shipping costs were also reasonable. The only issue I experienced is that it is virtually impossible to get order status from their Website if you do not have an account. Anytime I used the link provided in the order confirmation E-Mail would always return an error.

Amazing shipping and low prices

Quite shipping and awesome support. Definately going to do business again.

So far so good
