Product Details

The Enginetech M40558-030 is a premium molybdenum-coated piston ring set designed for Ford FE engine family, specifically the 360, 390, and 410 cubic inch V8 engines. This .030 inch oversize ring set is engineered for engine rebuilds requiring slightly oversized pistons due to cylinder boring operations.

Key Specifications:

  • Ring widths: 5/64" (top compression), 3/32" (second compression), 3/16" (oil control)
  • Bore size: 4.050 inches (102.87mm)
  • Oversize: .030 inch
  • Configuration: 8-cylinder complete set
  • Material: Premium moly-faced compression rings with high-quality gray iron construction

Important Installation Notes:

  • This ring set does not fit 1966-1967 OE pistons - aftermarket pistons required for these model years
  • Always verify piston groove dimensions before installation
  • Manufactured in OE facilities using the highest quality materials

Cross-Reference Numbers: Dana-Perfect Circle 40134CP, Federal Mogul E-180K, Hastings 2M574
