Akerly-Childs 19525-5 Xtreme Piston Ring Set for 4.380-Inch Bore, High Tension

Upgrade engine sealing performance with the Akerly-Childs 19525-5 Xtreme piston ring set. Designed for engines with a 4.380-inch bore, this file-fit ring set is engineered for precise installation and dependable operation in high-performance applications. The set is configured for 8-cylinder engines and includes high-tension rings made from ductile iron with a plasma moly face coating for enhanced durability and wear resistance.
The file-fit design allows the end gap to be adjusted to suit the engine build, operating conditions, and performance requirements. With a 0.017-inch thickness and 1/16-inch and 3/16-inch ring profiles, the Akerly-Childs 19525-5 supports consistent compression control and effective oil management when properly fitted and installed. High-tension construction helps maintain ring contact with the cylinder wall, supporting reliable sealing across demanding driving and racing conditions.
Plasma moly technology provides a durable running surface designed to promote extended service life and stable performance during break-in and continued operation. The ductile iron construction offers strength and resilience under elevated cylinder pressures, while the precision-focused file-fit format gives builders greater control over final ring-gap specifications. Verify bore size, groove configuration, ring placement, and application requirements before installation to ensure compatibility with the intended engine combination.
