Ford New Venture NV271F Transfer Case Parts
http://www.quad4x4.com/fordNV273Fparts.html
Depending upon the year and transmission, Ford New Venture NV271F manual shift transfer cases will have one of three Input Shaft choices. 31 Spline input shafts were used for 1999-2004 models with 4 speed automatic transmissions and 1999-2002 trucks with ZF5-47 5 speed manual transmissions. 2003 and 2004 applications are not so cut and dried because Ford VIN based parts lookup usually shows the 31 spline input being used with 5R110W 5 speed automatics behind Diesel and V10 engines, but the transfer case assemblies listed for the same vehicles have 34 spline input shafts. A 24 spline input will be found on 1999-2002 transfer cases in V10 or Diesel trucks with ZF 6 speed manual transmissions. For the 2003 model year, the 24 spline 6 speed input shaft was replaced by a 34 spline input shaft. The 34 spline input is used on all 2005-2010 Super Duty models with all engine and transmission combinations. Link to our Ford Web

The diameter of the NV273F Rear Output Shaft is considerably larger than any previous Rear Output Shaft used on Ford 4x4 Transfer Cases. The Output Shafts are both use fixed type round flanges. Front output shafts were built in an early and late version. While they are interchangeable if you also replace the sprocket snap ring, I feel the 1999-2004 Front Output Shaft is preferred for competition or really heavy-duty use, due to the full length spline and the early Sprocket Snap Ring is significantly thicker than the one used with the later shaft.Link to our Ford Web Page Index
