White Box Speed Shop's popular cast aluminum oil pans (PN# WB11004 and WB11005) are designed to swap LS engines into trucks, muscle cars, and more that require additional clearance on the front half of the oil pan. These vehicles are exposed to prolonged sessions of braking, turning, and accelerating need extra protection from oil starvation. That's where the WB11006 oil pan baffle comes in. This oil pan baffle kit is designed to maintain proper oil level at the oil pump pick-up during vehicle accelerations, both lateral and linear. The baffle maintains the oil at the oil pump pick-up preventing loss of engine oil pressure during maximum cornering in a high-performance touring or road-racing, as well as under hard acceleration in drag racing vehicles. The baffle is fabricated from sheet aluminum, and TIG welded for strength. One-way directional trap doors allow oil flow towards the oil pump pick-up but not away. This baffle is designed to be used in the White Box Speed shop GM Ls retro-fit oil pans (#WB11004 and #WB11005) with a standard pickup, and is a drop-in replacement for the standard tray baffle.
