Improved Racing designed this baffle and crank scraper kit specifically for the wet sump C6 Corvette oil pan. This second generation kit offers variants with clearance for 4.000" stroke engines with most aftermarket connecting rods and crankshafts as well as ARP main studs.

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 nearly 2% at the wheels. Gains of up to 9 WHP can be expected on a 500 WHP engine.

Improved Racing's second generation crankshaft scrapers are CNC-machined from 0.190" thick, 6061-T6 billet aluminum, making them twice as strong as our first generation steel scrapers. The trap door baffle has been updated to accept ARP main studs and clear up to 4.000" stroke setups. Because the baffle itself acts as a windage tray in this configuration, no windage tray is required.

The baffle crankshaft scrapers and 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.
