What does 'file fit' mean for these piston rings?

File fit means the ends of the top and second rings are intentionally made slightly too long. You will need to carefully file them down to achieve the correct end gap for your specific cylinder bore size and engine application. This allows for precise tuning of ring seal.

What is the ring tension for this set?

This single ring set is designed for applications that require 7 to 11 pounds of ring tension. This specification is important for ensuring proper sealing against the cylinder wall.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and this 87.5mm single ring set is no exception. If you're rebuilding an engine and need to set your piston ring end gaps precisely, these file-fit rings are the way to go. They allow you to custom-machine the gap to your specific cylinder bore and application, ensuring optimal sealing and performance.

This set features a 1.2mm top ring, a 1.2mm second ring, and a 2.8mm oil ring. The 'file fit' designation means you'll need to carefully file down the ends of the top and second rings to achieve the correct clearance in your cylinder bores. This is a standard procedure for many performance engine builds where exact tolerances are critical. The rings are designed for applications requiring 7-11 lbs of tension.

Please note that these rings are not CARB approved and cannot be shipped to California. Also, be aware of California Proposition 65 warnings associated with this product.
