What is the advantage of plasma moly steel construction?

Plasma moly steel construction offers enhanced durability and reduced friction compared to standard cast iron rings. This coating helps the rings wear in properly with the cylinder walls, leading to a better seal and longer engine life.

What does the '1.5MM x .151 RW' specification mean?

This refers to the dimensions of the piston rings. The '1.5MM' is the thickness of the top compression ring, and '.151 RW' indicates the width of the second ring. These precise measurements are critical for proper piston-to-cylinder wall sealing.

Are these rings suitable for all engine builds?

These rings are designed for a 4.100-inch bore and feature a plasma moly steel construction, often favored for performance or heavy-duty applications requiring robust sealing and wear resistance. It's important to confirm they match your specific engine's requirements and build goals.

Product Details

These Mahle piston rings feature a 1.5mm top ring thickness and a plasma moly steel construction, designed for a 4.100-inch bore diameter. This bulk pack contains 48 sets, making it a solid choice for engine builders or shops working on multiple engines. The plasma moly coating on the steel rings is known for its durability and ability to reduce friction, which is crucial for long-term engine health and performance. This type of ring is often used in performance or heavy-duty applications where consistent sealing and wear resistance are paramount.

The specific dimensions, 1.5mm for the top ring and .151 inches for the second ring's width, are important for ensuring a proper seal between the piston and cylinder wall. This precise fitment helps maintain compression, control oil consumption, and prevent blow-by, all of which contribute to an engine's overall efficiency and power output. Mahle OE rings are well-regarded in the industry for their consistent manufacturing and reliable performance, especially when rebuilding engines where precision is key. This bulk pack offers a cost-effective solution for projects requiring a significant quantity of high-quality piston rings.

When installing these rings, it's important to follow the manufacturer's recommended procedures to ensure optimal performance and longevity. Proper cleaning of the piston grooves and cylinder walls is essential. Remember that this product is not CARB approved and cannot be shipped to California.
