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.
