Oil Pan 4WD/Truck GM LT Swap - Natural

The WEIAND Oil Pan 4WD/Truck GM LT Swap in natural aluminum is a purpose-built engine oil pan kit engineered for GM GenV LT-series engine conversions in 4x4 trucks and performance vehicles. This rear-sump design delivers the complete hardware package needed for seamless LT engine integration into platforms that demand reliable oil management under demanding terrain and extreme operating conditions.

With a 5.6-quart capacity, the kit includes an internal baffle system that maintains consistent oil delivery to the pickup tube during aggressive off-road angles and rapid directional changes common to 4WD operation. The aluminum construction provides weight savings over stock steel pans while offering excellent thermal dissipation. All fasteners, the pickup tube assembly, and a protective cover are included, eliminating the need to source individual components. The natural finish resists corrosion in harsh environments where salt spray and moisture exposure are unavoidable.

This kit targets serious enthusiasts performing LT engine swaps into first-gen and second-gen Silverado and Sierra trucks, as well as custom 4x4 builds where space constraints and mounting geometry differ from stock LS configurations. The rear-sump design accommodates frame rails and transfer case clearance requirements that front-sump pans cannot manage. Fabricators and engine builders rely on this complete kit to avoid fabrication delays and ensure proper oil circulation from first start.

LT engine swaps demand precision component selection; using a generic pan risks inadequate oil return, cavitation, and bearing starvation under load. The WEIAND rear-sump design addresses the specific geometry requirements of truck-based LT installations, making it the engineered solution for builds where fitment and reliability cannot be compromised.
