Product Details

The MAHLE 3021274B is a high-performance steel piston ring set engineered for demanding racing and performance applications. This professional-grade ring set features MAHLE's THM-13 coating technology for enhanced durability and reduced friction.

Key Specifications:

  • Bore size: 4.175 inches (106.05mm)
  • Top ring: 1.5mm performance steel construction
  • Oil ring: 0.150-inch standard tension
  • Napier-style second ring design for improved oil control

  • Bulk packaging for professional engine builders

MAHLE performance ring sets are manufactured to exacting tolerances using premium materials and advanced coating technologies. The Napier ring design provides superior oil control while the steel construction ensures consistent sealing under high-temperature, high-stress racing conditions. These rings are designed for professional installation and require proper ring gap filing and fitting to engine specifications.

Got my order fast and everything was correct. Thanks for the good deal, just need some rear ones next.

Great transaction. The bike rack was about $90 less than a local retailer, and shipping was faster than promised. I wish all internet retailers were this reliable and useful.
