Oil Galley Plug GM LS 99-13 Front 41/64

The Oil Galley Plug GM LS 99-13 Front 41/64 is a precision block component designed for General Motors LS-series engines manufactured between 1999 and 2013. This product is essential for mechanics who are rebuilding or modifying LS powerplants, as it plays a critical role in maintaining proper oil distribution and engine longevity.

This front-mount plug, with a diameter of 41/64 inches, seals the factory oil passage in the engine block, ensuring effective oil flow to the crankshaft, camshaft, and valve train. DURA-BOND is known for producing components that meet OEM standards, making this plug a reliable direct replacement for worn or damaged original plugs. Proper installation is straightforward, requiring only a socket and wrench, along with light thread sealant.

Whether you're performing a full LS engine rebuild, upgrading to a high-capacity oil pump, or swapping an LS into a non-factory platform, this plug is crucial for ensuring optimal performance. Builders working with stroker cranks or high-flow cylinder heads will find this component particularly beneficial, as it helps prevent vacuum leaks and pressure loss in the oiling circuit.
