Jeep Jargon: Terms To Know

Souped Up

This refers to any Jeep Wrangler that has been modified with various custom Jeep parts and accessories to look and ride like a finely tuned off-roading beast.

Jeep Mods

This term is relatively easy to discern, but these are the custom modifications that are applied to any Jeep Wrangler. They can refer to the custom Jeep parts and accessories being applied for improving the look or the performance of the vehicle. In terms of their level of modifications and customization, there are three types of Jeep Wranglers you’ll find on the roads:

  • Stock - A Jeep without any custom Jeep parts or modifications performed outside of what was installed by the manufacturer.
  • Built - A Jeep which has been completely modified by a professional with custom Jeep parts for maximum performance and capabilities


This term is used to describe the various custom Jeep parts that serve as exterior protection when installed onto a Jeep Wrangler — bumpers, sliders, rocker guards, skid plates, fenders and more.


This is the act of performing work on your Jeep, whether it’s installing new custom Jeep parts and mods, giving it a tune-up, or repairing a broken or damaged component. Wrenching applies to any time you’re getting down and dirty with your Jeep in the garage or workshop, rather than out on the trails.


Wheeling is the term used by jeepers to describe trail running, rock climbing, and everything else you do off the pavement in your Wrangler.


Bogging, or “mudding,” refers specifically to times where you take your Jeep out in the mud. If you’re new to the off-road scene, we highly recommend sticking to traditional “wheeling” for a while before trying your hand in the mud pits — and when you do, have a winch nearby. If you do decide to take a dive into the mud, read our off-road driving tips first.

Locking Differentials

Also referred to often as “lockers,” these greatly improve your Jeep’s capabilities in low-traction environments, such as ice and sand. When they are needed, lockers will “lock” the left and right wheels of an axle together, providing a boost in traction for getting through tough terrain.

Aftermarket Jeep Accessories

Death Wobble

A dreaded occurrence throughout the Jeep community, the death wobble is an ill-fated effect of the suspension of your Wrangler, which leads to very intense front-end vibrations, or “wobbles.”

Overall, this is caused by the oscillation of the front axle, and it has the potential to end in a disastrous fashion if not addressed immediately. This happens most often when aftermarket Jeep lift or suspension kits are made poorly or have been installed improperly, but it can happen with any Jeep, stock or aftermarket, with the perfect storm of conditions. Learn more about the Jeep death wobble and how to fix it.


Articulation is the amount of distance that a Jeep’s suspension will allow the wheels to reach upwards and downwards. There are two forms of articulation:

  • Droop - downward articulation, or how far the tires can reach below the vehicle
  • Stuff - upward compression, or how far the tires can be pushed upwards into the wheel housing

Tire Bead

The tire bead refers to the edge of the tire that sits on the wheel rim, creating an air-tight seal. When the tire is inflated and the seal is formed, this is known as “sealing the bead.”


In a variety of off-roading scenarios, the tire bead can be compromised. For example, when climbing over rocks, tire pressure is reduced from what is used in daily driving to more easily climb. When pressure is reduced, the bead can easily become compromised. Many Jeep owners will buy a ‘bead lock’ for this very occurrence to help the bead hold, therefore maintaining tire pressure.

We hope that this guide to Jeep lingo will help you on your quest to become a Wrangler aficionado.
