Holley 302-4BK GM LS Swap Oil Pan 4WD / Truck / Off-Road Black Fits 1973-1987 GM K10 LS Swapped Trucks and Other 4WD LS Swap

GM's popular LS engines find their way into a huge variety of vehicles. Unfortunately, the factory LS pans don't always fit in the vehicles we would like.

Holley's new LS 4WD Off-Road Engine Swap Oil Pan is designed to help. It provides maximum clearance to the chassis and drivetrain for the K10 chassis and other LS swapped 4WD applications, plus provides an OE (Original Equipment) Style fitment for durability and proper sealing.

In addition, the 302-4 and 302-4BK are compatible with all popular transmissions (SM465, NV4500, TH350, TH400, 700R4, 4L60-4L70, 4L80, 6L80 and 6L90). Holley also offers an optional off-road hinged door baffle (#302-33 for LS engines and #302-34 for Lt engines) and rock shield (#302-35) that can be added at any time to further protect your investment.
