Your low-gear settings have helped you creep over some tough terrain in your time, but sometimes those settings just aren't low enough. The last thing you want is to encounter boundaries when you're off-roading, which is why installing a crawler box might be the right move for you and your vehicle. These parts are fairly simple to install, and work alongside your current settings to help you crawl over tough terrain that may not have been accessible with your former limited technology.

Getting Started
In order to get the results you really need, you'll likely require the use of a number of adapters during the installation process. This ensures your new NP231 crawl box is able to interface correctly with your existing transfer case and power source, so it can then provide you with the force you need to keep moving forward. The types of adapter you'll need relies largely on the type of transfer case and transmission you have installed in your truck, Jeep or SUV. It may be easier in some cases to purchase a complete NP231 crawl box kit instead, which should give you everything needed for a proper installation in one convenient place.

Installation
Again, the installation procedure depends on what type of vehicle you have, which transmission you use and where your transfer case is located. One crawl box might need to be installed the transfer case and transmission, while yet another might belong elsewhere. Some might require shifter knobs while others do not. Therefore, it's always a good idea to do a bit of research and reach out to one of our expert staff members for advice before making your purchase if you don't quite know what you're looking for.

A Guarantee You'll Love
The only thing better than getting new power for your ride in the form of a 231 crawl box is getting that power for a bargain. Our low price guarantee allows us to offer you the best deal out there because it allows us to match any lower prices you might find, for up to 90 days after you complete the transaction.

When your off-road vehicle looks brown instead of its original color, you know you've had a successful off-road adventure. On other days when you're not satisfied with your ride's performance, you may consider modifying the vehicle by adding a crawler box to enhance it. 4 Wheel Parts has you covered...
