Rear Oil Passage Plug Barbell GM LT Gen-5

The Rear Oil Passage Plug Barbell GM LT Gen-5 by MOROSO is a precision-engineered oil galley plug designed specifically for General Motors Gen-V LT-series engines. This component serves as a critical sealing element in the engine's lubrication system, preventing oil leakage at the rear oil passage while maintaining system integrity under varying operating pressures and temperatures. Built for enthusiasts and professional technicians who demand OEM-quality replacements or performance upgrades, this plug is essential for maintaining proper oil circulation in modern LS-based powerplants.

Manufactured from durable aluminum and featuring a reliable O-ring seal design, the Rear Oil Passage Plug Barbell ensures a press-in installation that creates a leak-free fit without requiring additional fasteners or thread sealants. The natural aluminum finish resists corrosion while the precision O-ring compresses uniformly to provide a positive seal across engine operating cycles. The barbell configuration allows for straightforward handling and alignment during installation, reducing assembly time and minimizing the risk of cross-threading or seal damage that can occur with traditional threaded plugs.

Ideal for engine rebuilds, performance modifications, or routine maintenance on Gen-V LT-series engines, this OEM-style replacement plug is compatible with a wide range of GM applications utilizing the latest LT platform architecture. Whether you're assembling a high-performance engine, servicing a street machine, or restoring original specifications, this Moroso component delivers reliable performance and a proper factory fit. Installation requires basic engine knowledge and appropriate press-in tools to ensure the plug seats correctly without damaging the aluminum body or compromising the seal integrity.
