Important Notes:
- Sized for cylinders bored .020 inch oversize. Verify your finished bore diameter with a precision gauge before ordering - rings sized for the wrong bore will not seal correctly.
- File-fit and gap each ring to the manufacturer's end-gap specification for your application before installation. Improper end gap causes blow-by or ring-end butting under heat.
- Replace piston rings as a complete set during any rebuild. One set covers all cylinders for the engine.

Enginetech piston ring sets are manufactured to OEM specifications and offered in both premium and cast grades to match the demands of stock rebuilds and moderate-performance builds. Each set is application-specific, with ring widths and end-gap characteristics matched to the bore and groove geometry of the engine family it serves. Ring sets are sold by bore size - standard for unmachined bores, with oversizes for blocks that have been bored and honed - so verify your finished bore diameter with a precision gauge before ordering, since rings sized for the wrong bore will not seal correctly. Always file-fit and gap each ring to the manufacturer's specification for your application, and replace rings as a complete set during any rebuild. Enginetech documents every set with the ring stack dimensions, bore size, and cross-references so the correct set reaches the bench the first time.
