3.622" Stroke LS, Vortec Engine Crank Scraper & Windage Tray Kit

These kits are compatible with most factory and aftermarket oil pan setups (see application list table below). 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. This equates to gains of up to 9 WHP on a 500 WHP vehicle. 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 crankshaft scraper kits also include an aluminum windage t
