Add horsepower and get superior protection for your GM LS stroker engine with Mast’s all-new Black Label windage tray. The custom engineered contours optimize oil return to the sump while providing optimum protection against oil splashback. The Mast Black Label windage tray fits all GM LS oil pans except 4th Gen F-Body that require a shorter tray and is ideal for racing or street/strip applications. The windage tray clears up to a 4.250” stroke crankshaft with H-beam connecting rods, is compatible with multiple pickup tubes, and accepts factory GM windage tray nuts.
