Hastings Piston Rings 1340cc .030 Over for Harley Davidson

Upgrade your Harley Davidson's engine performance with this high-quality Hastings 1340cc .030 Piston Rings set. Engineered for optimal sealing and durability, these rings are essential for a complete engine rebuild or refresh, ensuring your motorcycle runs at peak efficiency.

Description

This Hastings piston ring set is specifically designed for Harley Davidson 1340cc engines from 1978-2017, including models like the Electra Glide Classic FLHTC 1340 and Sportster Hugger XLH 883. These .030" oversize rings provide a precise fit for rebuilt engines, restoring crucial compression and oil control. The kit includes a complete set of top compression rings, second compression rings, and oil control rings for two pistons. The top compression rings feature a barrel face design, optimizing heat transfer between the piston and cylinder wall while effectively controlling combustion chamber gases. This allows the piston to efficiently transfer the energy of expanding combustion gases to the crankshaft, maximizing power output.

The second compression rings utilize a reverse torsional taper face, a design that significantly promotes side sealing. This innovative feature prevents oil from being forced under and behind the ring, leading to improved oil economy and reduced consumption. Its reverse twist, combined with a taper-machined ring face, effectively scrapes oil from the cylinder wall, duplicating the performance of a positive twist torsional ring. For superior oil management, the three-piece Flex Vent oil control rings are designed with small cross-sectional area rails for exceptional conformability to the cylinder bore. Uniform pressure is maintained through four steel rails and two expanders, guaranteeing positive oil control. Proudly made in the USA, Hastings piston rings deliver the reliability and performance serious riders demand.
