This set includes four complete piston ring kits from Supertech, designed for Subaru engines with a 93mm bore. Each kit contains the necessary rings for one piston: a 1.2mm top ring, a 1.5mm second ring, and a 4.0mm oil control ring. These are essential components for rebuilding or refreshing your engine's top end, ensuring proper sealing between the piston and cylinder wall.

Supertech is known for making well-built engine parts, and these piston rings are no exception. The specific ring sizes—1.2x3.30mm for the top ring, 1.5x3.7mm for the second ring, and 4.0x3.65mm for the oil control ring—are designed to meet the precise specifications needed for optimal performance and durability in your Subaru engine. Proper ring installation is key to preventing blow-by and oil consumption, so take your time and follow the manufacturer's guidelines.
