The LS Barbell Oil Galley Plug, often referred to as the "barbell," is a crucial component in LS-series GM engines. This small but vital part plays an integral role in maintaining proper oil control and pressure within the engine.
The LS Barbell is located behind the timing cover and is responsible for directing oil flow within the engine block. It separates the oil that feeds the lifters from the oil used to lubricate the camshaft bearings, ensuring that the oil goes where it's needed most and preventing any possible cross-contamination.
The LS Barbell's unique design helps maintain optimal oil pressure throughout the engine. It's made of high-quality materials to ensure durability and longevity, even under harsh conditions inside an engine.
For those who are rebuilding or tuning up their LS engine, the LS Barbell Oil Galley Plug is an essential component to check and replace if necessary. It's a small part that plays a big role in keeping your engine running smoothly and efficiently. These barbells have a smaller less restrictive shaft and replaceable high-temperature Viton o ring that completely seals the oil gallery barbell in LS engine block for better engine protection.
How We Choose the Best LS Barbell Oil Galley Plug
When it comes to choosing the best LS Barbell Oil Galley Plug, there are a few key factors to consider. First and foremost, you want to make sure that the plug is made of high-quality materials that can withstand the demanding conditions within an engine. Look for plugs made of durable materials such as stainless steel or aluminum.
You also want to ensure that the plug has been designed specifically for LS engines. This will ensure proper fitment and compatibility with your engine, maximizing its performance and longevity.
Another important factor is the design of the plug itself. Look for a barbell-shaped plug with smooth edges that can easily direct oil flow without any obstruction or restrictions. This will help maintain optimal oil pressure and prevent any potential damage to your engine.

The factory plastic barbell has a clearance of about .020”, allowing particles up to 500 Microns to leak past it. When oil leaks through, it bypasses filtration and reaches critical engine components like the Cam Bearing, Lifters, Crank, and Rod Bearings. Most oil filters can only trap particles as small as 25 Microns, depending on the brand. Their Precision Billet Aluminum Barbell provides a tighter fit with a .001” clearance, allowing only 20-25 Microns to pass through – comparable to the filter's efficiency. Additionally, the shaft of the Barbell plays a key role in oil flow. This Billet Barbell features a 30% smaller shaft, reducing flow restrictions significantly.

GM Gen V LT Engine Billet Rear Galley Plug Barbell Oil Diverter
Improved Racing's billet aluminum rear passage plug enhances oil flow in GM Gen V small block engines ("LT" series) by preventing dirty engine oil from bypassing the filter. Unlike the plugs for Gen III & IV ("LS" engines), this plug stands out with its unique length and diameter.
Featuring a second O-ring, Improved Racing's passage plug effectively separates dirty oil from clean oil, ensuring that all oil flow passes through the filter. Precision machining techniques are employed to eliminate sharp corners in favor of smooth fillets, promoting optimal oil flow. The bullnose tip further aids in seamless oil flow to the filter.
With a smaller shaft diameter compared to the OEM plastic barbell, flow restriction is minimized. Additionally, a threaded hole at the plug's end allows for easy removal using any M4x0.7 screw.
LS Barbell FAQs
What does the barbell do?
The barbell acts as a flow control device, regulating oil flow from the pickup tube to the main oil gallery in the engine. The stock plastic barbell is designed for a specific amount of oil flow. Upgrading to an aluminum rear galley plug can increase oil pressure and improve overall engine performance.
What are the benefits of upgrading to a billet aluminum plug?
A billet aluminum plug, like the Improved Racing barbell, has a smaller shaft diameter compared to the stock plastic one. This allows for less flow restriction and improved oil flow through the engine. The bullnose tip also helps promote smooth oil flow to the filter for better filtration.
How do I install and maintain my LS barbell?
Installation of the Improved Racing LS barbell is a straightforward process and can be done by following basic instructions or seeking professional help. The plug comes with two O-rings, which should be replaced if there are any signs of wear or damage. A rebuild kit is available for purchase if necessary.
Are there any additional benefits to upgrading to a billet aluminum plug?
Aside from better oil flow and durability, upgrading to a billet aluminum plug can also provide better sealing properties. The stock plastic barbell may develop leaks over time due to wear and tear, whereas the aluminum plug provides a tighter seal.
Conclusion
The oil gallery plug in your LS-based engine is something that is overlooked. And yet it serves a very important mission of directing oil to the oil filter. If oil leaks past the barbell it will go unfiltered directly to the cam bearings, lifters, crank, and rod bearings causing unfiltered oil back into your oil pan. The plastic factory barbell isn't the best solution to stop the smaller particles from bypassing the oil filter.
Whether you are looking for improved oil flow, durability, or additional features, upgrading to a billet aluminum LS barbell is a worthwhile investment for any LS engine owner. Get yours today!
