Manley Piston Ring, RING-100mm/3.937 1.5,3mm GAPLESS TOP

This set includes Manley Performance gapless top piston rings designed for a 100mm (3.937 inch) bore. You'll receive rings with a 1.5mm top ring and a 3.0mm second ring, both featuring a gapless design. This specific configuration is crucial for high-performance engine builds where sealing is paramount.

The gapless top ring design is a notable feature, meaning the ring ends meet without a gap. This creates a more effective seal against the cylinder wall, preventing combustion gases from blowing past the piston. This improved sealing can lead to better power output and more consistent engine performance, especially under demanding conditions. The rings are constructed from durable materials suitable for performance applications, aiming to withstand the heat and pressure found in modified engines. Proper installation is key to realizing the benefits of this design; ensure your cylinder walls are honed correctly and the rings are seated properly according to Manley's specifications.

Please note that these rings are not CARB approved and cannot be shipped to California. Additionally, they are subject to California's Proposition 65 warning. Always refer to the manufacturer's detailed installation instructions to ensure correct fitment and performance for your specific engine build.
