Crank Scraper for 3.622" Stroke Gen III & IV LS / Vortec Engines Crank Scraper for 3.622" Stroke Gen III & IV LS / Vortec Engines Improved Racing Improved Racing's crankshaft scrapers (also known as crank wipers) help reduce oil starvation by closely contouring the crankshaft and rods to remove excess oil, ensuring more oil makes it to the bottom of the sump. Crank scrapers also help reduce parasitic drag and windage losses caused by excess oil on the crank, which reduces rotational mass and results in a typical gain of 2-5 horsepower at the wheels. This crank scraper is designed to be sandwiched between the main caps and windage tray. It's designed to work with factory 3.622" stroke LS1/LS6, LS2, LS3 and Gen III and IV Vortec engines and is compatible with all windage trays and oil pans used in those engines. It is compatible with both factory oil pan baffles and Improved Racing oil pan baffles, in addition to most aftermarket rods. Note: Choose "Gen III LS" if you have an LS1, LS6 or Gen III Vortec engine with stock internals. For all others listed under "Applications" below, choose "Gen VI LS". These scrapers are not compatible with aftermarket hardware such as ARP rod bolts or main studs, but are compatible with most aftermarket rods.
