Each ring set is for one piston

Wiseco rings only fit Wiseco pistons

The Wiseco 7900YBX piston ring set is designed for dependable replacement performance in compatible engine applications. This precision-manufactured ring set helps restore proper cylinder sealing, support efficient combustion, and maintain consistent engine operation when paired with the correct Wiseco piston and cylinder configuration.
The 7900YBX set is specified for a 79.0 mm piston and uses a .9 mm top ring with a 1.5 mm second ring. These ring specifications are intended to match the required piston groove configuration, making accurate application verification essential before installation. Use this Wiseco ring set as a service replacement or during an engine rebuild where the original rings require replacement due to wear, loss of sealing, or routine maintenance.
Each set is supplied as a matched ring package for one compatible piston application. Follow the engine manufacturer’s installation procedures for ring orientation, end-gap inspection, groove cleaning, and break-in. Confirm piston compatibility, ring groove specifications, and application details before ordering to help ensure proper fit and reliable operation.
