Piston Ring Set 4.380 HTD HT .017 1/16 3/16

The Piston Ring Set 4.380 HTD HT .017 1/16 3/16 is designed for engine builders and mechanics focused on performance applications. This precision ring set is essential for sealing combustion pressure and controlling oil consumption, particularly in modified or racing engines. It is suitable for rebuilding classic performance blocks or restoring worn engines to factory specifications.

Featuring a 4.380-inch bore diameter, this ring set is optimized for mid-sized displacement engines. The HTD (High-Temperature Duty) designation indicates enhanced material properties to withstand elevated combustion temperatures. The .017-inch top ring gap, along with 1/16-inch and 3/16-inch secondary ring thicknesses, ensures effective sealing and minimizes friction losses during operation.

This piston ring set is ideal for engine rebuilds and racing engine assembly, providing the necessary reliability for high-performance applications. It is crucial for maintaining compression integrity and controlling blow-by, making it a valuable component for any serious engine builder.
