If you have the 261or 263 HD transfer case a great way to identify what chain and sprockets you need is by the transmission it is married to.
If married to either a 4L60e or a 4L80e transmission then this is the transfer case sprocket & chain that you need.
If your transfer case is married to an Allison/Duramax transmission you have the XHD model.
