The Jeep Gladiator is a pickup truck that stands out for its strong off-road abilities. One feature that many off-road fans want is differential lockers—special devices that help all wheels turn together for better traction. But not every Gladiator comes with lockers. If you’re thinking about buying one or want to know more, this article will help you understand which Jeep Gladiator models have lockers, why they matter, and what else you should consider.
What Are Lockers And Why Do They Matter?
Lockers, or locking differentials, connect the left and right wheels on the same axle. This means both wheels spin at the same speed, even if one is slipping. In tough terrain like mud or rocks, lockers help prevent getting stuck because power reaches both wheels.
Most trucks and SUVs come with open differentials, which send power to the wheel with the least resistance. That’s not good when one wheel is in the air or on loose ground. That’s when lockers make a big difference. They’re useful for:
- Rock crawling
- Deep mud and sand
- Slippery hills
Without lockers, it’s easier to lose traction and get stuck. So, if you want the Gladiator for more than just city driving, lockers can give you peace of mind and more adventure options.
Jeep Gladiator Trim Levels: Which Have Lockers?
Not every Gladiator comes with lockers. Let’s look at the main trims and what they offer.
| Trim Level | Front Locker | Rear Locker | Notes |
|---|---|---|---|
| Sport / Sport S | No | No | Base trims, no lockers |
| Overland | No | No | Focus on comfort, not off-road |
| Rubicon | Yes | Yes | Both front and rear, standard |
| Mojave | No | Yes | Rear only, tuned for high-speed desert |
| Willys | No | No (Trac-Lok LSD) | Limited slip, not full locker |
Rubicon: The True Off-road King
If you want front and rear lockers, choose the Gladiator Rubicon. It comes with Dana 44 axles and electric locking differentials on both ends. You can activate the rear locker in 4-High or 4-Low, and the front only in 4-Low. This model also includes:
- Off-road tires
- Sway bar disconnect
- Heavy-duty suspension
The Rubicon is the go-to for serious off-roading. No other Gladiator trim matches its locker setup.
Mojave: Desert Runner With Rear Locker
The Gladiator Mojave is built for high-speed desert driving. It has a rear locker only. The front end uses a standard open differential, but the rear locker still helps in loose sand or when traction drops.
Willys And Other Trims: Limited Slip, Not Lockers
The Willys trim comes with a Trac-Lok limited-slip differential in the rear. This is not the same as a locker. It helps if one wheel slips, but it won’t force both wheels to turn together like a true locker. Entry-level trims like Sport and Overland don’t have lockers or limited-slip, focusing more on comfort and daily driving.
How To Check If A Gladiator Has Lockers
If you’re looking at used Gladiators or want to check your own, here’s how to know:
- Check for Axle Lock buttons on the dashboard. Only Rubicon and Mojave will have these.
- Look under the vehicle. Lockers often have wiring going to the differential.
- Ask the dealer for a window sticker or build sheet.
- Use the VIN on Jeep’s website to check equipment.
Buyers sometimes confuse limited-slip with lockers. Double-check before you buy.
Locker Operation: How Do They Work In The Gladiator?
The lockers in Gladiator are electronic. You press a button, and a motor locks the axle. But there are rules:
- Rear locker can be engaged in both 4-High and 4-Low (Rubicon, Mojave)
- Front locker (Rubicon only) works in 4-Low
If you turn too sharply with lockers on, it can be hard on the drivetrain. Use lockers only when needed.
| Locker Location | Engage Mode | Best For |
|---|---|---|
| Rear Only | 4-High, 4-Low | Most off-road, mud, sand |
| Front & Rear | 4-Low only | Serious rock crawling |
Should You Add Lockers To Other Gladiator Trims?
Some owners want lockers but don’t buy a Rubicon or Mojave. You can add aftermarket lockers to other trims, but it’s costly:
- Parts can cost $1,500–$3,000 per axle
- Labor adds $1,000 or more
- May affect warranty
Also, factory lockers are integrated with other off-road systems. Aftermarket kits sometimes lack this, making them less user-friendly. For most, it’s simpler (and cheaper) to buy a Rubicon if you want lockers.
Other Gladiator Features That Help Off-road
Lockers are not the only thing that matters. The Gladiator Rubicon also includes:
- Rock-Trac 4×4 system for better crawl ratios
- Sway bar disconnect for more wheel movement
- Skid plates for underbody protection
- All-terrain tires
The Mojave, while made for speed, has Fox shocks and a special frame for desert running. The Willys uses a limited-slip, but it’s not as strong as a true locker.
Non-obvious Insights For Buyers
- Lockers help most when one tire loses contact (like on rocks or in deep ruts). If you drive mostly on flat dirt, you may not need them.
- Limited-slip diffs like Trac-Lok are not lockers. They help, but can’t match a true locker in extreme conditions.
- Some drivers rarely use lockers, even on hard trails. Good tires and driving skill go a long way. Lockers are a safety net, not a cure-all.

Frequently Asked Questions
What Is The Main Benefit Of Lockers In A Jeep Gladiator?
Lockers ensure that both wheels on an axle spin together, giving you more traction in tough off-road conditions. This prevents one wheel from spinning while the other stands still.
Which Jeep Gladiator Trims Have Both Front And Rear Lockers?
Only the Rubicon trim comes with both front and rear locking differentials as standard equipment.
Is The Trac-lok Limited-slip The Same As A Locker?
No, Trac-Lok helps if one wheel slips, but it doesn’t force both wheels to move together like a true locker. It’s less effective in extreme off-road situations.
Can I Add Lockers To A Gladiator Sport Or Overland?
Yes, you can add aftermarket lockers, but it’s expensive and may affect your warranty. Factory lockers offer better integration with the Jeep’s systems.
How Do I Know If My Gladiator Has Lockers?
Look for the Axle Lock button near the dashboard controls, check your window sticker, or use your VIN to check the Jeep’s official build sheet.
If you plan to tackle tough trails, lockers are a must-have. For everyday driving or light off-roading, they’re nice to have, but not essential. Choose the Gladiator that fits your adventure style.
