This high-quality piston ring set is designed to provide reliable performance and improved engine efficiency.
Each set includes four piston rings: two compression rings, one oil control ring, and one top oil ring. The compression rings are made from a durable, heat-resistant material that ensures a tight seal between the piston and cylinder wall, reducing engine blow-by and improving combustion efficiency. The oil control ring, on the other hand, helps to control oil consumption by directing oil to the piston skirt, reducing oil consumption and improving engine lubrication.
The top oil ring, the final ring in the set, helps to prevent oil from leaking past the piston and into the combustion chamber. This is especially important in high-performance engines, where excess oil can lead to engine knocking and reduced power output.
The NOS Hastings Standard Piston Ring Set is compatible with Toyota Corona, Hilux, and Crown models with a cylinder bore of 88mm.
