Hastings Piston Rings for 3.498" Bore, +0.040" Oversize

Enhance your engine's performance and longevity with the Hastings Piston Rings for 3.498" bore, engineered for precision and durability. This comprehensive set provides superior sealing and heat transfer, crucial for maintaining optimal engine health.

Description

These Hastings Piston Rings are meticulously designed to deliver exceptional engine performance and reliability. The set includes top compression rings, second compression rings, and oil control rings, all crafted to exacting standards. The top compression rings feature a barrel face design, optimized to facilitate efficient heat transfer between the piston and cylinder wall, while precisely controlling combustion chamber gases. This ensures maximum energy transfer from expanding combustion gases to the crankshaft, boosting overall power output. The second compression rings utilize a reverse torsional taper face, specifically engineered to promote superior side sealing. This critical design element prevents oil from being forced under and behind the ring, leading to improved oil economy and reduced consumption. The reverse twist ring, combined with a taper-machined face, effectively duplicates the scraping edge of a positive twist torsional ring, further enhancing its sealing capabilities. For uncompromising oil control, the set incorporates three-piece Flex Vent oil control rings. Their innovative three-piece construction allows for rails with a small cross-sectional area, ensuring better conformability to the cylinder bore. With uniform pressure maintained through four steel rails and two expanders, these rings guarantee positive oil control, preventing blow-by and maintaining lubrication integrity. Manufactured with a durable Moly Coated ring material and proudly Made in the USA, this piston ring set is a testament to quality and precision engineering, designed for a 3.498" bore with a +0.040" oversize.
