It runs a 2,200 to 2,800 RPM stall and is built with a much thicker lock-up liner and a modified stator to keep the converter cooler and address the factory converter's problem areas. It uses a factory 13 in core, an 11.675 in bolt circle, a 35-spline input shaft, an oversized extreme-duty single-disk lock-up, an extreme-temp heavy-duty O-ring, and a 1.703 in crank pilot. Make sure your gear ratio matches your setup, especially with taller tires. 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 4L80E, 4L85E (LS, lock-up)\u003c\/li\u003e\n\u003cli\u003eStall Speed: 2,200-2,800 RPM\u003c\/li\u003e\n\u003cli\u003eCore: 13 in (factory)\u003c\/li\u003e\n\u003cli\u003eBolt Circle: 11.675 in (factory)\u003c\/li\u003e\n\u003cli\u003eInput Spline: 35\u003c\/li\u003e\n\u003cli\u003eImpeller Hub: 2 in snout, hardened chrome moly\u003c\/li\u003e\n\u003cli\u003eLock-Up: Oversized extreme-duty single disk; extreme-temp heavy-duty O-ring\u003c\/li\u003e\n\u003cli\u003eBearings: Torrington-style encased\u003c\/li\u003e\n\u003cli\u003eStator: Modified extreme duty\u003c\/li\u003e\n\u003cli\u003eCrank Pilot: 1.703 in\u003c\/li\u003e\n\u003cli\u003eBolt Size: 10mm x 1.5 (Class 10.9+)\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: 49482\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.
