• Description:

  The Mopar Hex Flange Head Bolt, Mounting (06513099AA) M12x1.75x91.50 is a genuine OEM engine fastener designed to securely attach the main bearing cap to the engine block. Built to Mopar factory specifications, this bolt ensures proper clamping force, precise fitment, and long-term durability for critical engine bottom-end components.

  Engineered for use in select Mopar engines, this hex flange head bolt features an M12 diameter with a 1.75 thread pitch and an overall length of approximately 91.50 mm (also referenced as 89.10 mm or 91.2 mm depending on application and measurement specifications). It is specifically used for securing the main bearing cap to the engine block, helping maintain crankshaft alignment and proper engine bearing support.

  Constructed from high-strength automotive-grade steel, this fastener is designed to withstand extreme engine loads, vibration, thermal cycling, and the stresses associated with internal engine operation. Its flange head design helps distribute clamping force evenly across the mounting surface while ensuring secure retention of the main bearing cap assembly.

  Proper installation of the main bearing cap bolts is essential for maintaining crankshaft stability, bearing clearance, and overall engine reliability. As a genuine Mopar component, this mounting bolt is manufactured to OEM standards to provide the fit, strength, and performance required for critical engine assembly applications.

  Designed as a direct replacement, this genuine Mopar hex flange head bolt installs using factory mounting locations and torque specifications, helping restore original equipment fit, function, and engine integrity.
