What does 'STL TOP' mean for these piston rings?

STL TOP indicates that the top ring is constructed from steel, which is known for its strength and wear resistance. This design is often chosen for performance engines that experience higher cylinder pressures and temperatures.

Are these piston rings a direct replacement for all engines with a 3.582" bore?

These rings are designed for a 3.582 inch bore, but specific ring groove dimensions and ring gap requirements can vary between engine models. Always consult your engine's service manual or Manley's specifications to ensure compatibility and proper installation.

What is the significance of the 1.5mm and 3mm ring sizes?

The 1.5mm top ring and 3mm second ring are common dimensions for performance piston ring sets. These sizes are chosen to balance sealing efficiency, oil control, and ring land strength within the piston.

About this part

Product Details

Manley Performance has built a solid reputation for making well-built internal engine components, and these piston rings are no exception. If you're rebuilding the top end of your engine, these rings are designed to create a tight seal between the piston and cylinder wall. This seal is critical for maintaining compression, controlling oil consumption, and ensuring efficient combustion. The STL TOP designation indicates a specific top ring material and design intended for high-performance applications where durability and sealing under stress are paramount.

These rings feature a 1.5mm top ring and a 3mm second ring, a common configuration for many performance builds. The steel top ring offers good strength and wear resistance, helping it maintain its shape and sealing ability even under high cylinder pressures and temperatures. Proper ring gap is essential for performance and longevity, so be sure to check the manufacturer's specifications for your specific application and bore size to ensure they are filed correctly. This set is not CARB approved and cannot be shipped to California.
