About the NP261-HD
The NP261HD transfer case was originally manufactured by New Venture Gear and is a manual shift unit. This model was manufactured with left side drop output and has a low gear ratio of 2.72 to 1. This unit offers a combination of 2-high, 4-high, neutral and 4-low.
The 261HD has a 32 spline front input, 32 rear slip output, female spline front output.

Our unique replacement case half completely eliminates the "pump-rub" issue. These case halves are made of heavy grade aluminum, not the thin magnesium used in the OE cases. In addition, the Transfer Case Express upgrade corrects a snap-ring groove issue and eliminates the need for as adapter plate.
