LH8 Oil Pan for LS Engine Swap Applications
Swapping an LS powerplant into a narrow 1955-2005 GM frame demands precise clearance and oil delivery solutions that the LH8 Oil Pan provides. It sports a low profile sump and an integrated pickup tube girdle that keeps the inlet submerged under lateral loads while clearing steering linkages and crossmembers. Machined for direct PF48 filter mounting from corrosion-resistant aluminum alloy, the pan bolts in without reshaping chassis rails and maintains consistent oil pressure through aggressive cornering, heavy braking and spirited driving for road and track settings.
Strategic Sump Chamber Design for Crankshaft Clearance and Oil Capacity
The LH8 oil pan features a carefully shaped sump chamber that clears steering linkages and crossmembers without altering the vehicle frame. Its low profile housing is widened around the crankshaft to maintain ample oil volume while fitting narrow engine bays. This design prevents the need for trimming chassis rails and preserves original frame geometry during engine swaps. By balancing clearance with reservoir capacity, the pan holds sufficient oil to supply the pump under sustained high engine speeds and lateral forces. The geometry also ensures that oil returns to the sump quickly, reducing slosh and preventing the pump from drawing air when cornering or braking. Vehicle builders gain confidence in consistent oil pressure and capacity without sacrificing fitment or requiring sheet metal work.
Precision Machined Flange and Weld Integrity for Reliable Sealing
Each LH8 pan is CNC machined on its sealing flange to achieve razor flatness and consistent bolt pattern alignment with GM frame rails. This precision machining creates a flawless sealing surface that mates perfectly with the engine block, reducing the likelihood of leaks even after repeated thermal cycles. The body is assembled using robust welds that fuse the aluminum walls without warping the structure, and sealed welds add extra protection against oil seepage. Wall thickness is engineered to resist flex under high output engines, ensuring the pan retains its shape under track use or spirited driving. Together, these manufacturing steps deliver long term durability and leak free performance, simplifying installation and minimizing maintenance concerns. Installers benefit from a pan that locks onto the block with predictable torque values and holds a secure seal without resorting to custom gaskets or sealants.
