Improved Racing Crank Scraper and Windage Tray Kits

Not Yet Reviewed

With the installation an Improved Racing crank scraper and windage tray kit, you'll enjoy additional horsepower and improved oil control from your factory 3.622 in.
With the installation an Improved Racing crank scraper and windage tray kit, you'll enjoy additional horsepower and improved oil control from your factory 3.622 in. or aftermarket 4.000 in. stroke LS engine. They reduce oil starvation by closely following the contours of the crankshaft and connecting rods to remove excess oil, ensuring oil is quickly returned to the bottom of the sump. The kits also reduce parasitic drag and windage losses caused by excess oil on the crank, reducing rotational mass and providing dyno-proven gains. Scraper/windage tray kits are available for most factory and aftermarket oil pan setups
With the installation an Improved Racing crank scraper and windage tray kit, you'll enjoy additional horsepower and improved oil control from your factory 3.622 in. or aftermarket 4.000 in. stroke LS engine. They reduce oil starvation by closely following the contours of the crankshaft and connecting rods to remove excess oil, ensuring oil is quickly returned to the bottom of the sump. The kits also reduce parasitic drag and windage losses caused by excess oil on the crank, reducing rotational mass and providing dyno-proven gains. Scraper/windage tray kits are available for most factory and aftermarket oil pan setups, and include a crank scraper (CNC-machined from 0.190 in. thick 6061-T6 billet aluminum) and aluminum windage tray (made from 5052-H32 aluminum) that provides more clearance for aftermarket rods than factory windage trays. The windage tray bolts directly to the scraper with self-clinching lock nuts instead of the main cap studs, so they can be installed without disturbing the alignment of the scraper.

Features and benefits include:

* No modifications required to OE oil pump pickup tube
* Bolt-on installation
* 70 percent stronger and 10 percent lighter than OE windage trays
* Lifetime warranty
* Minor clearancing around counterweights may be required for aftermarket 4.000 in. stroker crankshafts
