5150 AutoSport Billet Main Cap Locating Dowels – BMW S58
These locating dowels are used when installing our 5150 AutoSport Billet Main Caps. They help keep the caps properly located in the engine block and prevent cap movement under high horsepower and RPM.
At extreme power levels, main cap movement can affect bearing alignment and oil clearances. Adding dowels helps keep everything in place and provides additional support for the bottom end.
Features:
-
Keeps billet main caps properly located in the block.
-
Helps reduce main cap walk under heavy loads.
-
Maintains consistent main bearing alignment.
-
Designed for our 5150 AutoSport Billet Main Caps.
Installation Note: Machining is required to install the dowels into the block and main caps. Proper alignment and main bore measurements must be verified during installation.
