What is a gapless top piston ring?

A gapless top piston ring has no gap, meaning the ends meet perfectly when installed. This design significantly reduces the amount of combustion gases that can leak past the ring, known as blow-by, leading to improved sealing and performance.

What does the 1.5mm, 3.0mm sizing refer to?

These measurements refer to the height of the piston rings. The 1.5mm is the height of the top compression ring, and the 3.0mm is the height of the second compression ring. This sizing is critical for proper fitment in the piston's ring grooves.

About this part

Product Details

This set includes the gapless top piston rings you need for your engine build. Specifically designed for a 4.035-inch bore, these rings feature a 1.5mm top ring and a 3.0mm second ring, engineered to create a tighter seal within the cylinder.

Manley Performance is known for its well-built engine components, and these gapless top rings are no exception. The gapless design means the top ring has no gap, which significantly reduces blow-by and helps maintain consistent cylinder pressure. This improved sealing can lead to better power output and more efficient combustion. The rings are made from durable materials to withstand the rigors of high-performance engines.

When rebuilding or upgrading your engine, proper ring seal is crucial for performance and longevity. These Manley rings are a solid option for builders looking for that extra edge in sealing efficiency. Please note that this product is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
