LH8 LS Oil Pan with Wider Crankshaft Clearance
When dropping an LS mill into a narrow GM chassis, the LH8 Oil Pan tackles both clearance and oil starvation risks by offering extra room around the crankshaft without reshaping frame rails. Its low profile housing and widened sump area clear steering linkages and crossmembers while the integrated pickup tube girdle secures the inlet so that lateral forces cannot starve the pump. Constructed from corrosion resistant aluminum alloy and machined for direct PF48 filter mounting, this oil pan aligns precisely with 1955 to 2005 GM frames to simplify installation and maintain consistent oil pressure under hard cornering or sudden braking.
Integrated Pickup Girdle Ensuring Steady Oil Inlet Contact
The LH8 pan features a pickup girdle that locks the main tube inside a reinforced chamber to maintain continuous oil inlet contact. This design holds the pump inlet submerged even during rapid lateral shifts, preventing momentary pressure loss that can harm crank bearings and cam journals under track or spirited driving. By securing the pickup without extra baffles or internal welding, the pan delivers a true drop in solution that bypasses the need for custom modifications. Engine starvation is eliminated under sudden stops, ensuring reliable engine operation under demanding maneuvers. The guided pickup tube also reduces stress on the inlet fitting, increasing service life of the assembly and preserving oil pump health. The result is consistent lubrication regardless of cornering forces or abrupt deceleration.
Corrosion Resistant Aluminum Alloy for Efficient Heat Management
Manufactured from a premium aluminum alloy, this oil pan combines reduced weight with superior thermal conductivity to dissipate heat far more effectively than steel alternatives. Under sustained load, the alloy resists distortion during thermal cycles, maintaining a flat sealing surface and preventing leaks even after repeated use. Its natural resistance to corrosion from water and chemicals found on the road extends service life and reduces maintenance requirements. The pan's robust wall thickness and sealed welds contribute to overall structural integrity and resist flex under high engine output. The reduced mass also contributes to faster engine response, lower rotating mass loads, and improved fuel efficiency. Together, these traits provide reliable cooling for extended track sessions or long highway runs.
Direct PF48 Filter Integration for Cleaner Oil Circulation
The LH8 chassis is machined to accept an AC PF48 filter directly under the pump outlet, eliminating the need for adapters and reducing potential leak points. Positioned in an optimal flow path, the filter captures contaminants before they can recirculate, safeguarding critical components and extending oil life. Simplified plumbing paths result in cleaner engine bay layouts and fewer fittings to manage, saving hours during installation and future servicing. The low mounting point also improves filter access for rapid oil changes without complex hose rerouting. Consistent oil pressure through the filter supports pump longevity and reliable lubrication under all driving conditions, from daily commutes to track duty.
Precise Fit across GM Chassis from 1955 to 2005
The pan's bolt pattern matches GM frame rails produced between 1955 and 2005, providing a direct bolt in installation without cutting or drilling. Its low profile sump clears steering linkages and crossmembers, allowing LS engines to slip into narrow engine bays with minimal modifications. For Gen III and Gen IV LS blocks the accurate flange layout reduces trial fitting and eliminates common clearance headaches that often arise with standard pans. Builders benefit from a design that preserves original frame geometry and minimizes body work. This universal approach simplifies engine swaps, giving installers confidence that the pan aligns perfectly every time, whether under a classic coupe or a modern truck chassis.
This LH8 Oil Pan delivers precise fitment and dependable lubrication for any LS chassis project.
