Piston Ring Set 4.000 Moly 1/16 1/16 3/16

The MAHLE ORIGINAL/CLEVITE Piston Ring Set 4.000 Moly 1/16 1/16 3/16 is designed for engine builders and mechanics who demand OEM-quality performance in high-performance or rebuilt applications. This piston ring set is essential for restoring proper ring seal, maintaining combustion pressure, and managing oil effectively across the piston deck. Whether you're working on a stroker engine, refreshing a vintage block, or upgrading a daily driver, quality piston rings are crucial for achieving reliable horsepower and longevity.

Manufactured by MAHLE ORIGINAL/CLEVITE, a reputable OEM and aftermarket supplier, this set features moly-coated compression rings with a 1/16-inch top ring and a 1/16-inch second ring, along with a 3/16-inch oil control ring. The moly coating enhances wear resistance, reduces friction, and aids in the rapid seating of the rings during the critical break-in period. This ring geometry is specifically calibrated for 4.000-inch bore diameter engines, ensuring optimal wall contact and effective blowby control.

Engine builders and mechanics trust MAHLE piston rings for their reliability in naturally aspirated, turbocharged, and supercharged builds, where OEM fitment is essential. Proper installation requires honing, inspecting piston grooves, and adhering to torque specifications as outlined in your engine's service manual. This attention to detail ensures that the piston rings perform optimally, contributing to the overall efficiency and performance of the engine.
