Oil Pan Gasket - 426 Hemi/KB/BAE 1pc.

The MOROSO Oil Pan Gasket for 426 Hemi, KB, and BAE engines is a single-piece, steel-core rubber gasket designed to provide reliable sealing between the oil pan and engine block. This gasket is engineered for Mopar RB-series big-block engines, where consistent oil containment and leak prevention are critical to engine longevity and performance. The steel-reinforced construction ensures durability under thermal cycling and maintains a tight seal across thousands of operating hours.

The one-piece design eliminates the multiple-gasket approach, reducing assembly complexity and the risk of leaks at junction points. Steel-core rubber gaskets are the industry standard for high-performance and classic engines because they resist oil degradation, maintain compression under vibration, and tolerate the temperature fluctuations inherent to engine operation. For 426 Hemi and RB-series applications, this gasket specification matches original equipment requirements and is suitable for both street and competition use. The gasket dimensions of 17.5 x 32.1 inches accommodate the full oil pan perimeter, ensuring comprehensive coverage.

This gasket is essential for engine builders, restoration specialists, and performance enthusiasts working on classic Mopar muscle cars, drag racing engines, and vintage hot rods equipped with 426 Hemi or RB-series powerplants. Whether replacing an original gasket that has hardened over decades or installing a fresh seal during a complete rebuild, this MOROSO product delivers the reliability expected from a manufacturer with deep roots in racing and engine specification. Proper gasket selection prevents costly oil leaks that compromise engine cleanliness and allow contaminant ingress.
