It runs a 2,200 to 2,800 RPM stall and is designed to strengthen the weak points of the factory converter with a much thicker, stronger lock-up liner, a modified heavy-duty stator, an extreme-temp heavy-duty O-ring, and new Torrington-style encased bearings so it handles more power and runs cooler. It uses the factory 12 in core, a 10.75 in bolt circle, and a factory 1.703 in crank pilot. Note the 27-spline input, which sets it apart from the 30-spline 48442; count the smaller set of splines to confirm. Every unit is leak and pressure tested, digitally balanced, and made in the USA.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSeries: Night Stalker\u003c\/li\u003e\n\u003cli\u003eTransmission: GM 700R4, 200-4R (298mm, lock-up)\u003c\/li\u003e\n\u003cli\u003eStall Speed: 2,200-2,800 RPM\u003c\/li\u003e\n\u003cli\u003eInput Shaft: 27-spline, three-step (count the smaller splines)\u003c\/li\u003e\n\u003cli\u003eCore: 12 in (factory)\u003c\/li\u003e\n\u003cli\u003eBolt Circle: 10.75 in\u003c\/li\u003e\n\u003cli\u003eLock-Up: Yes (extreme-duty); extreme-temp heavy-duty O-ring\u003c\/li\u003e\n\u003cli\u003eImpeller Hub: Hardened chrome moly\u003c\/li\u003e\n\u003cli\u003eBearings: Torrington-style encased\u003c\/li\u003e\n\u003cli\u003eStator: Modified heavy duty\u003c\/li\u003e\n\u003cli\u003eCrank Pilot: 1.703 in (factory)\u003c\/li\u003e\n\u003cli\u003eBolt Size: 10mm x 1.5\u003c\/li\u003e\n\u003cli\u003eAnti-Balloon Plates: No\u003c\/li\u003e\n\u003cli\u003eBalance: Digitally balanced\u003c\/li\u003e\n\u003cli\u003eBuild: Leak \u0026amp; pressure tested; made in USA\u003c\/li\u003e\n\u003cli\u003ePart Number: 48402\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWARNING: This product can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm.
