MAHLE Performance Piston Ring Set Bore File Fit

The MAHLE Performance piston ring set line gives engine builders file-fit piston rings for performance and racing engines. File-fit rings are supplied with an unfinished end gap. You file the gap to match your bore, piston and power-adder setup. This lets you set precise ring end gap clearances, which are key to good cylinder sealing, power and ring life. These sets are also known as performance piston rings or racing ring sets.

Key Features:

• File-fit design lets you set the end gap to suit your build
• Performance Series construction is designed for high-output street, drag, circle track and other racing engines
• Advanced coatings and materials are offered across the line. These include plasma-moly faced rings and steel top rings with MAHLE's HV385 thermal-spray process, depending on the part number
• Multiple ring thickness and tension options are offered, so you can match the ring package to your piston ring grooves and application
• Engineered with MAHLE's ring design experience, including computer simulation and development, to help control ring seal and wear

MAHLE Motorsports supplies race teams across many top racing series. Choose the child option that matches your bore, ring groove dimensions and tension requirements. Always confirm and set the proper ring end gap during assembly.
