Oil Pan 4WD/Truck GM LT Swap - Black

The Oil Pan 4WD/Truck GM LT Swap - Black by WEIAND is purpose-built for enthusiasts undertaking a modern LS-based LT engine swap into classic trucks, muscle cars, and 4x4 platforms. When retrofitting GM's cutting-edge GenV LT-Series engine into a chassis originally designed for older powerplants, the factory oil pan no longer fits—or doesn't position correctly for ground clearance and suspension geometry. This rear-sump pan solves that problem with a drop-in design engineered specifically for truck applications where underbody space is constrained.

Constructed from lightweight aluminum with a durable black powder-coat finish, this 5.6-quart capacity pan features an integrated baffle system that maintains oil supply to the pickup tube during aggressive cornering, acceleration, and off-road articulation. The complete kit includes the pan, cover, pickup assembly, and all necessary mounting hardware, eliminating the need to source fasteners separately. The rear-sump configuration positions the pickup at the deepest point of the pan, ensuring consistent oil delivery to the LT engine's high-volume pump even during severe suspension compression or extreme lean angles typical of 4WD operation.

This pan is ideal for builders converting first-generation Chevrolet and GMC trucks, Broncos, Blazers, and similar platforms to modern LT propulsion. Its compact 15 x 11-inch footprint and 24.3-inch depth allow fitment in tight engine bays while maximizing ground clearance—critical for lifted 4WD trucks and low-slung classic restorations. Verify your specific LT variant and frame configuration before purchase; rear-sump design requires adequate clearance below the transmission and crossmember. Installation typically requires custom motor mounts and exhaust routing, making professional fabrication guidance recommended for first-time swappers.
