Summary

    Improved Racing designed this crank scraper specifically for use with the C5 Corvette "Batwing" oil pan setup. Because these oil pans are shallow and well-baffled, a windage tray section isn't required and only the scraper section of our kit is included.

    Improved Racing's 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.

    These 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.

    The 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.

    Crank 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.
