Rebuild a classic V8 with the Sealed Power Engine Piston Ring Set E-175X, a Vintage-line ring set that reseals the combustion chamber, holds compression, and controls oil film on the cylinder walls. It's a direct-fit set for many vintage Ford and Mercury V8 applications — including the 1956-1957 Ford Thunderbird, 1964-1965 Ford Mustang, 1962-1965 Mercury Comet, and more — covering the V8-4.3L and V8-5.1L engines. This is an 8-cylinder set (Quantity Per Application: 1) for one engine.
Vintage coverage: part of the Sealed Power Vintage program, developed to support engine rebuilds on applications over 35 years old.
Ring build: top and second rings in grey iron with a phosphate coating; second-ring face is a reverse torsional design; oil ring uses a 3-piece Flex Vent design (0.1875 in wide).
Standard-bore fit: 3.8000 in bore diameter with groove widths of 5/64 x 3/32 x 3/16; not oversized and not file-fit.
Premium grade: made to exacting tolerances with ISO & QS certified manufacturing and built to meet or exceed OEM specifications.
It's cataloged for the V8-4.3L and V8-5.1L engines in many vintage Ford and Mercury models, such as the 1964-1965 Ford Mustang and 1962-1965 Mercury Comet. Check the Buyer's Guide tab for the full list.
What comes in this set?
It's an 8-cylinder piston ring set covering one V8 engine, with top, second, and oil rings. The Quantity Per Application is 1, so one set services the engine.
What are the ring specifications?
The set is built for a 3.8000 in bore with groove widths of 5/64 x 3/32 x 3/16 and a 0.1875 in oil ring width. It is a standard-bore set — not oversized and not file-fit.
What are the rings made of?
The top and second rings use grey iron with a phosphate coating. The second-ring face is a reverse torsional design and the oil ring is a 3-piece Flex Vent design.
What are signs the piston rings may need replacing?
Blue exhaust smoke, high oil consumption, low compression, or excess blow-by can point to worn rings. Diagnose the cause first; if worn rings are the issue, this set replaces them during a rebuild.
