- This rebuild kit fits New Venture and New Process 263XHD Extra Heavy Duty transfer cases. Please check your transfer case tag and verify your model number is 263 XHD GM. This kit will not fit LD or HD models as each model has different size bearings, pump splines, and chain widths and link counts.
- Our rebuild kit includes a bearing, gasket, and seal kit with high quality Japanese bearings. No Chinese garbage anywhere in this kit. Included are all new internal bearings, input and output seals, all new o-rings, (2) planet thrust washers, range fork inserts, and a new tail housing snap ring grommet.
- All Rigid Axle rebuild kits include case halfs that come reinforced around the pump. The BRNY wear plate and Merchant Automotive pump upgrade kit are NOT needed. This will save you time and money! Our casting features a precisely machined oil pump seat that fixes the "pump rub" issue found on the OEM magnesium models. Your pump will no longer wear through the case causing leaks. Even though the BRNY transfer case wear plate is not required, it can be used for extra insurance and peace of mind. This casting also features strengthened ribs with 5mm more material. If that isn't enough, each case is 100% leak tested before it leaves our facility. Our case half comes with two threaded sensor ports, a sensor port plug in case your truck only requires one speed sensor, a tailshaft bushing already pressed in, and the output shaft needle bearing already installed. You are guaranteed to get a far superior product when ordering through Rigid Axle!
- The transfer case chain is the second biggest headache when you own one of these units. In our experience, the chains start to stretch around 160,000 to 200,000 miles. When the chain stretches a number of things can happen. One sign of a stretched chain is a loud popping sound heard when the transfer case is under load. That sound tells you the chain has stretched enough to skip on the teeth of the sprockets. At that point, not only are you eating up sprockets, but you're sending metal through your transfer case. Don't let metal go through your planetary or the cost of your rebuild just went up significantly!
- Wouldn't you be upset if you took your vehicle in for a full oil change and the mechanic didn't replace your oil filter? Well, we would. That's why we include a new oil pump filter screen with every NP261/NP263 kit that is sold with a new pump. Keep your transfer case protected and well lubricated with our pump and filter kit.
