• Description:

  The Mopar Front Main Crankshaft Seal (4663618) is a genuine OEM engine sealing component designed to prevent engine oil leakage at the front of the crankshaft. Manufactured to Mopar factory specifications, this seal ensures precise fitment, reliable sealing performance, and long-term durability while helping maintain the integrity of the engine lubrication system.

  Specifically engineered for the front crankshaft position, this seal is installed where the crankshaft exits the front of the engine block or timing cover area. Its primary function is to retain engine oil within the engine while preventing contaminants such as dirt, dust, and moisture from entering the crankshaft opening. Proper seal performance is essential for maintaining oil pressure, reducing oil loss, and protecting critical engine components.

  Constructed from high-quality automotive-grade sealing materials, this front main crankshaft seal is designed to withstand continuous crankshaft rotation, engine heat, pressure variations, and long-term exposure to engine oil. Its durable construction helps resist hardening, cracking, wear, and premature deterioration while maintaining dependable sealing characteristics throughout its service life.

  Designed as a direct replacement for the original component, this front crankshaft seal utilizes factory dimensions and specifications for proper installation and OEM-quality fitment. Replacing a worn, leaking, or damaged seal can help restore proper engine sealing, prevent oil leaks, and maintain overall engine reliability.
