NP263 Pumps

Having trouble keeping your transfer case lubricated? We have the NP263 pumps and accessories you need to get it working again. The NP263 was used in GM trucks from 2003–2007 and came in several versions, including “LD” for light-duty trucks, “HD” for heavy-duty gas trucks and “XHD” for heavy-duty diesel trucks. The input shafts on these models may have 29, 31 or 32 splines. NP263 oil case tubes and pumps are different between these versions, so be sure to check the part description. We list models, spline counts and compatible part numbers, so you can be sure you’re ordering what you need for your transfer case.

If you need these parts, be sure to check the rear case half. The NP263 pump assembly has a design flaw that can cause it to wear a hole in the case.
