These high-quality piston rings fit both the original Ford pistons and the SCCA-legal forged pistons (standard 3.188" / 81mm bore only) on the Formula Ford 1600 Kent "Uprated" engine. This is a full set of rings for 4 pistons (enough for one complete engine).
Our rings are oversized to give you enough extra material to file the ring end gaps as tight as you like.* The oil rings in this set have standard tension for better sealing at the expense of a little friction. You can adjust the tension to your exact requirements by slightly tweaking the oil ring expander. Proper ring preparation and fitting is detailed in Chapter 9 of Jake Lamont's book How to Build Competitive (yet legal) FF1600 Engines. Ask your machine shop to finish the cylinder walls for moly rings.
* These rings are oversized and must be filed (gapped) to fit your engine.
Note: These rings ONLY fit the standard 81mm bore (after filing to fit). If you have re-honed your cylinders to the SCCA-permitted 0.005" oversize (3.194"), you will need different rings to fit the 0.005" oversize pistons.
