Special applications engine sump

Designed for high-performance engines with cylinder bores of 4.000"
The camshaft support plate moves 0.250" outwards to allow the crankcases to accommodate large-diameter pistons.
With tolerance for races up to 5,000"
Relocating the oil pickup on the camshaft support plate increases transmission sump anchorage and virtually eliminates oil drag at constant high revs.
Machined to accommodate the standard oil filter assembly used in Big Twins from '92 to '99
An enlarged duct with ports and a machined vent window allows oil mist from the rotor cavity to flow to the engine camshaft support plate with minimal restriction.
Crankcase ventilation can be achieved via two crankcase breathers, the cylinder heads, or both; S&S recommends using both crankcase breathers on engines larger than 95".
Platform height: 5.875"
Made in the USA
Machined for installation with a crankshaft position sensor, allowing the use of the crankcases in electronic fuel injection applications and also enabling easy installation of the S&S IST ignition and VFI fuel injection; a set is included.
All S&S sump pans manufactured after 1 June 2008 have no slot or locking ring and do not use alignment dowels. The mating surface is flat, and alignment is achieved via locating bushes.
