MAHLE Drop-In Piston Ring Set Bore

The MAHLE Drop-In Piston Ring Set is a piston ring set for engine rebuilds and repairs. It is engineered so the rings can be installed without custom end-gap filing, which saves time during assembly. Each set is made for a specific cylinder bore size, so you can match the right set to your engine build.

Key Features:

• Drop-in design with pre-set ring end gaps, so no file fitting is normally needed
• Made by MAHLE, an original equipment supplier with a long history in piston and ring technology
• Complete ring set for an engine rebuild, with compression and oil control rings
• Built to seal combustion pressure, control oil consumption, and move heat from the piston to the cylinder wall
• Precision manufacturing for consistent fit and reliable ring seating

Whether you are rebuilding a daily driver or a performance engine, MAHLE piston rings help restore compression and engine efficiency. Choose the bore size that matches your application from the available variants.
