Oil Pan kits
The High Clearance Oil Pan pan is needed if running factory style power assist steering and will fit similar to the original engine. The f-body oil pan gives a little more ground clearance and is recommended for extremely lowered cars, but does not clear the factory power assist slave cylinder. It does work great with cars that have been converted to a power steering gearbox. Includes windage tray, pickup tube, hardware, and gasket.
Oil pan kits come with our exclusive pickup tube girdle.
BRP Oil Pump Pickup Tube Girdle
Original GM oil pickup tubes are fastened to the pump with a single bolt mating flange on the tube. The bolt hole on the other side is not used. Our Girdle is cnc machined aluminum and goes over the original mating flange, wraps around the tube, and fastens using both bolt holes. Use with a little Locktight and it’s cheap insurance against an engine meltdown. It comes with two longer bolts for install.
