LH8 Oil Pan for LS Engine Swap Installations
When fitting an LS engine into a narrow GM chassis the LH8 Oil Pan addresses the risk of oil starvation by maintaining reservoir contact under hard cornering or sudden braking. Its low profile sump and integrated pickup tube girdle lock the pickup in place so the pump inlet stays submerged even when lateral forces shift the oil away from the reservoir. Crafted from corrosion resistant aluminum alloy it dissipates heat faster than steel pans and aligns precisely with 1955 through 2005 GM frame rails to clear steering components and crossmembers without cutting or drilling. Direct PF48 filter compatibility further simplifies plumbing and sustains clean oil flow under demanding driving conditions to protect critical engine components.
Integrated Pickup Tube Girdle for Constant Oil Delivery
The LH8 pan features an integrated pickup tube girdle that locks the oil pickup securely in place, keeping the pump inlet submerged even under sudden stops or sharp turns. By holding the tube within a reinforced chamber, the design prevents momentary oil pressure loss that can starve critical bearings and camshaft journals. This approach removes the need for additional baffles or internal modifications, offering a straightforward drop-in solution. As a result, lubrication remains continuous under lateral forces, protecting engine components during spirited driving or track sessions.
High Grade Aluminum Alloy for Rapid Heat Dissipation
Constructed from a corrosion resistant aluminum alloy, the LH8 pan combines structural rigidity with superior thermal conductivity to cool oil faster than steel alternatives. Under sustained load, this material resists warping through repeated thermal cycles, maintaining flat sealing surfaces and preventing leaks. The reduced weight also contributes to a lower overall mass, which can improve throttle response and reduce stress on the engine block. Long term durability is enhanced by the alloy's natural resistance to moisture and road chemicals, ensuring the pan remains free from pits and corrosion.
Precision PF48 Filter Mounting for Simplified Plumbing
This oil pan is machined to accept an AC PF48 filter element directly under the pump outlet, eliminating adapters and minimizing seal points. With the filter positioned in a clean flow path, contaminants are captured before recirculating, reducing engine wear and extending oil life. The direct mount location streamlines plumbing runs, making installations faster and neater, especially in tight engine bays. Consistent oil flow through the filter maintains steady pressure, supporting pump longevity and reliable lubrication under all driving conditions.
Direct Bolt In Fitment across GM Frames from 1955 to 2005
The LH8 pan uses a precise flange pattern that aligns with GM frame rails manufactured from 1955 through 2005, allowing a direct bolt-on installation without cutting or drilling. Its low profile sump tucks close to the block face, clearing steering components and crossmembers found in classic and late model chassis. For Gen III and Gen IV LS blocks, the matching bolt pattern reduces mock-up time and eliminates common clearance headaches. Builders benefit from consistent fitment that preserves original frame geometry and simplifies engine swap projects.
