LH8 Oil Pan for LS Engine Swap Installations
For anyone installing an LS mill into a tight 1955 to 2005 GM frame the LH8 Oil Pan solves sump clearance and oil starvation issues. Its low profile sump and integrated pickup tube girdle keep the inlet submerged under lateral force while clearing steering linkages and crossmembers. Precision machined flanges match PF48 filter interfaces directly to Gen III and IV blocks without modifying chassis rails. Installers gain consistent oil pressure under aggressive cornering and heavy braking thanks to optimized sump geometry and corrosion resistant aluminum construction.
Pickup Tube Girdle Ensuring Submerged Inlet Under Lateral Loads
The LH8 oil pan's integrated pickup tube girdle holds the inlet securely in place to maintain oil flow even when the vehicle is subjected to hard cornering or sudden braking. By bracing the pickup tube against engine block movement, the girdle prevents the inlet from rising out of the oil reservoir and drawing air. This design minimizes the risk of oil starvation during track sessions or spirited street runs where g forces shift fluid away from a conventional sump. Technicians will appreciate that the girdle installs directly onto the pan without additional brackets, streamlining assembly. The result is a stable supply of lubricant to the LS engine pump under aggressive driving conditions.
Seamless PF48 Filter Integration for Enhanced Contamination Control
By matching the pan flange to GM's PF48 oil filter footprint, the LH8 oil pan allows direct mount of the filter assembly without custom adapters or modifications. This precise interface reduces potential leak points and aligns the filter housing squarely with the block, simplifying torque specifications and service procedures. Employing a widely available PF48 element ensures access to a range of high quality filtration media to capture particulates and protect critical engine components. Keeping contaminants out of the oil extends component life and helps preserve performance of the LS powerplant. Installers benefit from a reliable, plug and play solution that delivers cleaner oil under all operating scenarios.
Corrosion Resistant Aluminum Alloy for Lightweight Strength and Heat Dissipation
Constructed from a premium aluminum alloy, the LH8 oil pan offers a balance of rigidity and weight savings critical for high output LS installations. The material resists corrosion from road salts and moisture, maintaining structural integrity over many seasons of service. Its thermal conductivity draws heat away from the sump, helping oil remain within optimal temperature range during sustained high rpm or heavy braking events. Precision welding and consistent wall thickness prevent distortion when the engine reaches operating temperature, maintaining a true seal against the block. Together, these attributes deliver a durable foundation for sump applications in narrow GM frames from mid-fifties to early millennial models.
Engineered to deliver reliable oil flow and exceptional durability in tight LS swap applications.
