LH8 Oil Pan for LS Engine Swap Applications
When fitting a Gen III or IV LS into a narrow GM engine bay the LH8 Oil Pan tackles oil starvation under cornering or sudden braking by using a low profile sump and an integrated pickup tube girdle to maintain reservoir contact. Crafted from corrosion resistant aluminum alloy it draws heat away from the oil faster than steel pans and endures repeated thermal cycles without warping. Its precise flange pattern aligns with 1955 to 2005 GM frame rails to clear steering components and crossmembers without any cutting or drilling. Installers gain direct PF48 filter compatibility to simplify plumbing and sustain clean oil flow under demanding driving conditions.
Pickup Tube Girdle Maintaining Constant Oil Supply
The integrated pickup tube girdle secures the oil pickup inside a reinforced pocket, ensuring the pump inlet remains submerged even when lateral forces shift the oil mass. This design prevents momentary pressure loss that can starve bearings and camshaft journals during aggressive cornering or sudden stops. By locking the tube in place, the LH8 pan delivers uninterrupted lubrication under high G loads without requiring internal baffles or extra modifications. Installers benefit from a straightforward drop-in assembly that keeps the oil reservoir in contact at all times, safeguarding critical engine components from wear and heat damage.
Aluminum Alloy Structure for Rapid Heat Dissipation and Durability
Crafted from a high-grade aluminum alloy, the LH8 pan offers a lightweight yet rigid enclosure that resists corrosion and withstands extreme thermal cycling without warping. Aluminum's high thermal conductivity draws heat away from the oil faster than steel alternatives, helping maintain stable oil viscosity under extended load or track conditions. The material’s natural resistance to road salt and moisture promotes long-term durability, while reduced mass contributes to a lower overall center of gravity. This combination of strength and heat management ensures reliable performance in both street and racing applications.
Direct AC PF48 Filter Integration for Cleaner Oil Flow
The LH8 pan is precision-machined to accept an AC PF48 filter element without adapters or additional fittings. This seamless integration cuts potential leak points and streamlines plumbing by positioning the filter directly beneath the pump outlet. The PF48 medium features a generous pleat design and fine filtration media that trap contaminants before they can circulate back into the engine. A simplified routing path reduces installation time and effort in tight bays, while consistent flow rates through the filter help preserve pump life and maintain steady oil pressure under all driving conditions.
Engine Bay Fitment for GM Chassis from 1955 through 2005
Engineered to align precisely with GM frame rails built between 1955 and 2005, the LH8 pan slips into narrow engine bays without any cutting or drilling. Its low-profile sump tucks close to the block face, clearing steering components and crossmembers on most classic and late-model chassis. The bolt pattern matches factory dimensions for a direct mount on Gen III and Gen IV LS blocks, simplifying swap work and reducing mock-up time. Builders appreciate this precise fit, which eliminates common clearance headaches and preserves the integrity of the original frame geometry.
Designed for precise fit and consistent oil management in LS swaps, the LH8 Oil Pan ensures reliable engine protection.
