Manley 46456GT-8 4.560" Bore Total Seal Gapless Top Piston Ring Set

The Manley 46456GT-8 is a Total Seal® Gapless® Top Ring Package designed for engines with a 4.560-inch bore. This 8-piece set (one ring per cylinder) is engineered for high-performance and forced-induction engine builds where minimizing blowby and maximizing cylinder sealing are critical.

Key Features:

• Total Seal® Gapless® Top Ring Technology — eliminates the end gap found in conventional top rings, dramatically reducing blowby and combustion gas leakage past the ring pack
• 4.560" Bore Diameter — precision-sized for large-bore performance engine applications
• .043" Top Ring Thickness — thin-profile design reduces radial tension and friction for improved power output
• 3/16" Oil Ring Width — standard oil ring width compatible with conventional ring groove pistons
• Steel Construction — premium steel top ring material for superior strength and durability under high-horsepower and high-temperature conditions

Important: Manley piston rings are purpose-built for use with Manley pistons. Verify bore size and ring groove dimensions match your specific piston before installation. Installed or partially installed rings are not eligible for return.
