Detailed Description

The Sealed Power E-183X piston ring set is made for classic engine rebuilds where correct bore size, ring width, and ring profile matter. With a 4.3000 in. bore diameter, 5/64 in. top ring, 3/32 in. second ring, and 3/16 in. oil ring, this set matches standard groove dimensions used in select vintage V8 engines. The barrel-face top ring, reverse torsional second ring, and 3-piece flex vent oil ring support proper sealing and oil control during restoration work. This part cross-references 50140 and BC1438 for the same application. It is a strong match for restoration projects involving Lincoln Continental, Ford Thunderbird, and Mercury Colony Park engines, including the Sealed Power E-183X application range.

Common Uses

  • Restoring worn piston ring sealing in vintage engines
  • Correcting oil consumption caused by aged ring sets
  • Improving compression retention during a rebuild
  • Replacing damaged or out-of-spec rings in standard bore cylinders
  • Supporting classic Lincoln Continental, Ford Thunderbird, and Mercury Colony Park engine rebuilds

Installation Notes and Tips

Verify bore diameter, ring groove widths, and cylinder condition before installation. The E-183X is a standard-size set and is not file fit, so ring end gaps should be checked against the engine builder’s specifications during assembly. Clean ring grooves thoroughly and confirm the piston and cylinder measurements match the listed 4.3000 in. bore and 5/64 x 3/32 x 3/16 in. groove widths. Fits 1958-1965 Lincoln Continental, N/A; Fits 1959-1960 Ford Thunderbird, N/A; Fits 1958-1960 Mercury Colony Park, N/A.

Quality Assurance

Sealed Power vintage components are manufactured with controlled materials and ISO- and QS-certified processes to support consistent performance and long service life in classic engine rebuilds.
