Manley Piston Ring, RING-4.040 1.5,3mm GAPLESS TOP

Manley Performance is well-known for making strong internal engine components, and these gapless top piston rings are a prime example of their commitment to performance. If you're building or rebuilding an engine where every detail matters, especially for boosted or high-RPM applications, these rings are designed to seal exceptionally well. The gapless top ring design means there's no gap for combustion pressure to escape past the top ring, which helps maintain consistent cylinder pressure and can improve power output.

These rings are specifically sized for a 4.040 inch bore and feature a 1.5mm top ring, a 3.0mm second ring, and an oil ring. The gapless top ring design is a notable feature that sets them apart from standard rings, offering improved sealing performance under demanding conditions. This can lead to better power delivery and more consistent engine operation, especially when you're pushing the limits. They are made from durable materials intended to withstand the rigors of high-performance use.

It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures to ensure optimal performance and longevity of your engine build.
