GM LS Alm R/R Oil Pan

The MOROSO GM LS Aluminum Rear Sump Oil Pan (Part No. 21152) is specifically designed for LS-powered vehicles that require a rear-mounted oil pan configuration. This product is essential for automotive enthusiasts and fabricators who are converting non-LS platforms or modifying existing LS installations where the stock pan geometry may interfere with suspension or chassis components. It is particularly useful for those building street rods or swapping LS engines into classic cars.

Constructed from lightweight aluminum, this rear sump oil pan reduces unsprung weight compared to traditional cast-iron alternatives while ensuring structural integrity under high-performance conditions. The aluminum material also enhances heat dissipation, which is crucial for maintaining optimal oil temperatures during extended driving or in high-performance scenarios. This design fundamentally alters the oil return path to the engine, allowing for more flexible chassis layouts.

Ideal for fabricators, restorers, and performance builders, this oil pan is compatible with GM LS engine families, including LS1, LS2, LS3, and LSx. Its design accommodates tight engine compartments without requiring extensive modifications to the surrounding chassis. This makes it a versatile choice for various automotive applications, ensuring that enthusiasts can achieve their desired performance and aesthetic goals.
