Product Details

The MAHLE 50787-030 is a precision-ground piston ring set engineered to OEM and performance standards. The -030 designation indicates a 0.030-inch oversize ring set, designed for use in bored or worn cylinders that have been machined to 0.030" over the standard bore size — a common specification during engine rebuilds.

MAHLE is a globally recognized OEM supplier and aftermarket manufacturer trusted by professional engine builders for consistent tolerances, superior metallurgy, and proven durability. These rings are manufactured to exacting dimensional standards to ensure proper sealing, oil control, and long service life.

Key Features:

  • 0.030" Oversize — designed for cylinders bored 0.030" over standard
  • Precision-ground profiles for consistent ring seal and minimal blow-by
  • OEM-grade metallurgy — high-strength cast iron or ductile iron construction (application-dependent)
  • Optimized face geometry for rapid break-in and long-term compression retention
  • Oil control ring included — full 3-piece ring set per cylinder or complete multi-cylinder set as applicable
  • MAHLE OEM-level quality — trusted by professional engine rebuilders worldwide

Ideal for engine rebuilds, performance builds, or high-mileage restorations requiring oversize components. Always verify bore measurements and confirm fitment with your specific application prior to installation.

Your prices for Metal Rescue were the best I could find and your shipping was fast, although I screwed up and ordered a quart when I though I ordered a gallon

Hello, i am very pleased with Autoplicity, i found that they have the best price for the item that i ordered. I ordered Borla Atak exhaust for my 2013 Mustang 5.0. they save me well over a 100.00 on this muffler. I will tell all my friends about this site too, so they can get on the band waggon and save some $'s.<br>:)
