{"product_id":"improved-racing-ls-ve-vf-crank-scraper-windage-tray-kit-4-0-stroke","title":"Improved Racing - LS, VE-VF, CRANK SCRAPER\/WINDAGE TRAY KIT, 4.0\" STROKE","description":"\u003cp\u003eCrank scraper \u0026amp; windage tray kit  to suit 4.0\" stroke LS engines, with either factory or aftermarket crankshafts and rods. These kits are compatible with most factory and aftermarket oil pan setups except low front clearance pans, Corvette pans, and front sump pans (see separate listings for those applications).\u003cbr\u003e\u003cbr\u003eImproved Racing's patented (Pat. No. D860,258) crankshaft scrapers help reduce oil starvation by closely contouring the crankshaft and rods to remove excess oil, ensuring oil is quickly returned 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 dyno-proven gains of 5-10 HP at the wheels.\u003cbr\u003e\u003cbr\u003eOur scrapers are CNC-machined from 0.190\" thick, 6061-T6 billet aluminum. The crankshaft scraper kits also include an aluminum windage tray that is 10% lighter, 70% stronger, and provides more clearance for aftermarket rods than the factory windage tray. The included windage tray bolts directly to the scraper with self-clinching lock nuts instead of the main cap studs, allowing it to be installed without disturbing the scraper alignment.\u003cbr\u003e\u003cbr\u003eThe crankshaft scrapers and windage trays were designed in CAD software using actual GM part models, prototyped, and test-fitted for a completely bolt-on fit in every listed application. The factory oil pump pickup tube is kept in the factory location with no compromises or modifications required.\u003cbr\u003e\u003cbr\u003eCrank Scraper kits are compatible with factory or ARP main cap studs. Reducer spacers as well as Class 10, flanged zinc-plated steel distorted thread lock nuts are included for use with factory main cap studs. For ARP main cap studs, use the nuts supplied by ARP.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan class=\"subHeading\"\u003eFeatures and Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncreases horsepower by up to 10 WHP\u003c\/li\u003e\n\u003cli\u003eScraper and windage tray assembly is 70% stronger and 10% lighter than the factory windage tray\u003c\/li\u003e\n\u003cli\u003eReduces oil starvation and aeration\u003c\/li\u003e\n\u003cli\u003e100% bolt-on installation\u003c\/li\u003e\n\u003cli\u003eWindage tray is secured with locking, vibration-resistant hardware\u003c\/li\u003e\n\u003cli\u003eIncludes reducer bushings and upgraded main cap stud lock nuts for factory studs\u003c\/li\u003e\n\u003cli\u003ePatented design (Pat.
