The Cometic GM LT1/L86/L87 4.125in Round Bore .58in MLX Head Gasket - C15427-058 is a precision-engineered head gasket with a 4.125" bore and .125" compressed thickness.

The Cometic MLX Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring MLX Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers for superior sealing under extreme cylinder pressures and temperatures. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.

  • Material: MLX Multi-Layer Steel (MLS)
  • Bore Size: 4.125"
  • Thickness: .125" compressed
  • Part Number: C15427-058

Verified fitment: Chevrolet Camaro (2016–2021); Chevrolet Corvette (2014–2019).
