MAHLE Piston Ring Set Bore File Fit Low Tension

The MAHLE Low Tension File Fit Piston Ring Set is a performance engine piston ring set for builders who want less friction and good ring sealing. MAHLE developed these rings using piston ring simulation and computer-aided design. The goal is to free up horsepower by reducing friction. Each set is a file fit design. You can gap the rings to your own bore and application during assembly.

Key Features:

• Top ring: plasma moly-coated ductile iron with a barrel-face profile for durable sealing and break-in
• Second ring: cast iron with a reverse twist design for good compression sealing and oil control
• Oil ring: low tension design to reduce drag against the cylinder wall
• Ultra-flat ring flanks: improve ring-to-piston sealing
• File fit: rings are sized so the end gap can be set to your build
• Ring thickness options: offered in conventional and ultra-low friction configurations across the product line

These piston rings are meant for performance and racing engines. They suit builders who want to cut internal friction while keeping cylinder sealing. Each part number is matched to a specific bore size. Choose the variant that matches your bore and ring groove dimensions.
