- This rebuild kit fits New Venture and New Process 273D transfer cases. Please check your transfer case tag and verify your model number is 273 D.
- Our rebuild kits include a bearing, gasket, and seal kit with high quality bearings. Included are all new internal bearings, input and output seals, all new o-rings, planet thrust washers, and range fork inserts.
- The transfer case chain is a high quality chain that will last and handle 4wd abuse. In our experience, your stock chain 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!
- This kit includes two new high strength sprockets. These sprockets will guarantee a clean engagement into your new transfer case chain. We always recommend upgrading to our sprockets when replacing a stock chain!
- 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 NP271/NP273 kit that is sold with a new pump. Keep your transfer case protected and well lubricated with our pump and filter kit.
- Before ordering, please verify the spline count on your input shaft. They made four variations of the NP271/NP273 input shaft so it is very important that you select the proper one before ordering.
