Difference Between the Jeep Wrangler’s Selec-Trac vs. Command-Trac 4x4 Systems

If you’re a Jeep enthusiast like all of us here at LiftedJeeps.com, then you’re probably aware of the fact that the automaker provides two different full-time drive systems for their iconic Wrangler SUV, with both being capable of switching between two- and four-wheel drive based on the road conditions in which you find yourself. However, do you know the difference between them? The two 4x4 systems that we’re speaking of are, of course, Selec-Trac and Command-Trac. Both are great options, but if you’re curious about the difference between them, we’re here to give you the full rundown today.

We’ll start by giving you the rundown on the Command-Trac 4x4 System, as it’s the standard 4WD system found standard on most Jeep Wrangler models. As mentioned, the system does allow drivers to swap between two- and four-wheel drive whenever they need. This ability is available even when driving at speeds of up to 55 miles per hour, which is pretty incredible. It’s an especially useful feature when switching between driving on ordinary roads and hitting the off-road trails you’re likely to tackle in your Wrangler.

The system features a two-speed transfer case with options for both high- and low-range gearing, with the former being better for regular driving and the latter enhancing off-road driving or towing. When the four-wheel drive system is triggered, it distributes torque evenly with a 50/50 split for maximized traction.

The Selec-Trac system, on the other hand, is an available upgrade in certain Wrangler trim levels, including Unlimited Sahara, Sport and 4xe models. While this system also allows you to switch into a two-wheel drive mode to maximize efficiency on ordinary, clear road conditions, it also offers five driver-selectable driving modes so that you can optimize power distribution and other aspects of the system based on the type of driving you’re doing. The five different modes include Track, Sport, Tow, Snow and Auto.

This system also features a two-speed transfer case, enabling seamless transition between the different modes. It also includes an automatic four-wheel drive mode, which will allow the vehicle to adjust its torque distribution between each wheel based entirely on the actual road conditions you face. It also includes a 2.72:1 low-range gear ratio and heavy-duty Dana front and rear axles, with the latter featuring a ratio of 3.45.

Hopefully, all of the above information has helped to discern the difference between the two systems, but you might still be asking yourself which one you should choose. To answer that question, you’ll have to ask yourself whether you want a part-time or full-time system, which will largely depend on how you plan to use your Jeep Wrangler. The full-time Selec-Trac system is great for everyday driving and the occasional off-road trek, while the Command-Trac system is the best option for off-road driving, tailored entirely to the types of activities you’ll be tackling.

All of this information should help you better understand what each system has to offer in addition to the differences between them. Really the major difference between the two systems is just the part-time versus full-time 4WD, so you’ll have to decide which style works better for the type of driving you’re going to do. We can of course answer any additional questions or dive into greater detail on what these two systems have to offer, so feel free to give us a call here at the sales desk if you’d like. We look forward to seeing you behind the wheel of a new lifted Jeep Wrangler!
