Improved Racing designed this crankshaft scraper and windage tray kit for direct bolt-on installation in aftermarket 4.000" stroke LS engine configurations. Scrapers are available for most popular aftermarket H-beam and I-beam connecting rods and are compatible with most factory and aftermarket oil pan setups (see application list table below). If you don't see your application below, please contact us for assistance.

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 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 factory location with no compromises or modifications required.

Outstanding quality and product. I had this installed in my GPI forged/stroked LSA build -- everyone commented on the outstanding workmanship and how great the instructions/installation was. Absolutely worth every penny.

Also installed the LS Oil Pan baffle, LS Oil pickup tube support, and their fantastic oil cooler hoses!

Very nice piece! Fit my stroker setup without an issue. For the price I wish they would of included new windage tray nuts or made it an option when placing the order.
