Enginetech S39116-020 is a premium .020" oversize piston ring set for 1992-2003 Dodge 3.9L 239ci V6 engines, sold as a complete set covering all cylinders.
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.
- Premium. Steel or Moly top. 2.0 / 2.0 / 4.0mm. Shallow oil ring.

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.
