Jeep TJ Jerry Can Mount: Secure Your Adventure Fuel
Reading Time: 8 minutes If you drive a Jeep TJ, you know that adventures often take you far from gas stations. Carrying extra fuel can be a real lifesaver, especially on trails or during long road trips. That’s why many Jeep owners consider installing a Jerry can mount. This simple upgrade lets you bring extra fuel safely and securely—no more worrying about running on empty in the middle of nowhere. But with so many options and installation styles, finding the right mount and using it correctly can be confusing, especially for beginners.
This article explains everything you need to know about Jeep TJ Jerry can mounts. We’ll cover types, installation tips, safety, and how to pick the best mount for your Jeep. If you’re new to off-roading or just want to be prepared, you’ll find clear, simple advice here.
Why A Jerry Can Mount Matters For Your Jeep Tj
The Jeep TJ has a small fuel tank—usually about 19 gallons. If you drive off-road, through remote areas, or on long trips, that’s sometimes not enough. A Jerry can mount allows you to carry extra fuel cans outside your Jeep, freeing up space inside and reducing fumes or spills.
Key reasons to use a Jerry can mount:
- Extra range: Carrying 5–10 extra gallons can add 100–200 miles to your trip.
- Safety: Keeps fuel outside the cabin, away from passengers.
- Convenience: Quick access to spare fuel when you need it most.
- Better weight distribution: Mounting cans outside or on the rear helps balance the Jeep.
Many Jeep owners say a Jerry can saved their trip at least once. For example, off-roaders on the Rubicon Trail often need extra fuel to finish the route.
Types Of Jerry Can Mounts For Jeep Tj
There are several styles of Jerry can mounts. Each fits different needs and budgets. Here are the main types:
1. Rear Bumper Mounts
These attach to the back bumper, often as part of a tire carrier system. They are popular because:
- They don’t block the rear window.
- They’re easy to access.
- Some allow you to carry more than one can.
2. Swing-out Tire Carrier Mounts
Many aftermarket tire carriers include spots for Jerry cans. These swing out with the spare tire, making it easy to open the tailgate.
3. Side Body Mounts
Some mounts attach to the Jeep’s side, usually behind the rear wheels. They:
- Are less common.
- Can affect visibility.
- Are easy to reach, but may reduce ground clearance.
4. Roof Rack Mounts
If you have a roof rack, you can install Jerry can holders there. These are great for long trips, but:
- Lifting heavy cans onto the roof is hard.
- Spilled fuel is more likely to drip down the Jeep.
5. Hitch-mounted Carriers
These fit into the standard 2-inch hitch receiver. They are easy to remove and work well for extra storage on long trips.
Comparison Of Popular Mount Styles
Here’s a quick comparison of the main mount styles for Jeep TJ:
| Mount Style | Capacity | Accessibility | Installation Difficulty |
|---|---|---|---|
| Rear Bumper | 1-2 cans | Easy | Medium |
| Swing-Out Carrier | 1-2 cans | Very Easy | Hard |
| Side Body | 1 can | Easy | Hard |
| Roof Rack | 2+ cans | Hard | Medium |
| Hitch Carrier | 1-2 cans | Easy | Easy |
If you’re new to modifying your Jeep, the hitch carrier or rear bumper mount is usually the simplest choice.
What To Look For When Choosing A Jerry Can Mount
Not all mounts are made the same. Here are important factors to help you choose the right one:
- Compatibility: Make sure the mount fits your Jeep TJ. Some are “universal” but may require drilling or adapters.
- Weight rating: Each mount has a weight limit. A full 5-gallon steel Jerry can weighs about 40 lbs. Carrying two means 80 lbs or more.
- Material: Strong steel is best for off-road use. Aluminum mounts are lighter but can bend more easily.
- Security: Look for locking features to prevent theft.
- Ease of use: Can you remove and replace the can quickly?
- Weather resistance: Powder-coated or stainless steel mounts last longer in harsh weather.
Here’s a simple data table comparing typical mount materials:
| Material | Strength | Weight | Rust Resistance |
|---|---|---|---|
| Steel | High | Heavy | Medium |
| Aluminum | Medium | Light | High |
| Plastic | Low | Very Light | High |
Most Jeep owners prefer steel for durability, but aluminum is good for less extreme use.
How To Install A Jerry Can Mount On Your Jeep Tj
Installing a Jerry can mount is a job most beginners can handle with basic tools. Here’s a general step-by-step for a rear bumper or hitch mount:
- Read the instructions: Every mount is a bit different. Always start with the manufacturer’s guide.
- Gather tools: You’ll usually need wrenches, a drill (for some mounts), and safety glasses.
- Position the mount: Hold the mount in place to check fitment and clearance. Make sure it doesn’t block the tailgate or lights.
- Mark the holes: For mounts that require drilling, use a marker or punch to mark where you’ll drill.
- Drill holes (if needed): Use the right size drill bit for your bolts. Go slow and wear safety gear.
- Bolt on the mount: Use the supplied hardware. Tighten all bolts fully.
- Test fit the Jerry can: Place the can in the holder. Make sure it fits snugly and doesn’t move.
- Check tailgate operation: Open and close the tailgate to ensure nothing is blocked.
Practical Example
Let’s say you buy a Smittybilt Jerry Can Holder for your Jeep TJ’s rear bumper. It comes with bolts and a strap. You line it up on the bumper, mark two holes, and drill them. After bolting it down, you strap in a full can and check for movement. The whole process takes about 30 minutes.
Tips For A Safe Install
- Use lock washers or threadlocker to stop bolts from loosening on rough trails.
- Paint drilled holes to prevent rust.
- Double-check all bolts after your first drive.
Safety Tips For Carrying Fuel
Carrying fuel on your Jeep is serious. A mistake can cause fires or spills. Here’s how to stay safe:
- Always use approved Jerry cans (steel or heavy-duty plastic).
- Never carry fuel inside the passenger area.
- Check for leaks before every trip.
- Secure the can tightly so it can’t bounce or slide.
- Keep fuel away from heat sources, like exhaust pipes.
- Do not overfill the can—leave space for expansion.
- Carry a small fire extinguisher in your Jeep.
Non-obvious insight: Many beginners forget to check if their Jerry can vent is working. A clogged vent can cause the can to swell or leak in hot weather.
How Much Extra Fuel Do You Need?
The right amount depends on your trip. Here’s how to estimate:
- The Jeep TJ gets about 15–19 mpg (miles per gallon) in real-world driving.
- A 5-gallon Jerry can gives you about 75–95 extra miles.
- For a long off-road trail, two cans (10 gallons) is usually enough.
But remember, carrying extra weight lowers your fuel economy. Plan for a little less range than you calculate.

Common Mistakes To Avoid
Even experienced Jeep owners make mistakes with Jerry can mounts. Here are the most common:
- Overloading the mount: Never exceed the weight rating.
- Loose installation: Bolts can loosen over time—check them regularly.
- Blocking the license plate or lights: This can get you a ticket.
- Using cheap plastic cans: They crack easily, especially off-road.
- Ignoring local laws: Some states have rules about carrying extra fuel outside the vehicle.
Non-obvious insight: If you drive in very hot climates, pressure can build up in your Jerry can. Open the cap slowly to release pressure safely.

Real-world Example: Off-road Trail Use
Imagine you’re taking your Jeep TJ on the Moab White Rim Trail in Utah. The full loop is about 100 miles with no gas stations. The Jeep TJ’s 19-gallon tank can cover about 285 miles on the road, but off-road driving uses more fuel—sometimes only 12 mpg. You might only get 228 miles per tank. Carrying two 5-gallon Jerry cans (10 gallons) gives you a safe buffer, letting you finish the trail and get back to a gas station.
Maintenance And Care For Your Jerry Can Mount
To keep your mount in good shape:
- Check all bolts and straps every month or after rough trails.
- Clean dirt and mud off the mount to stop rust.
- Spray moving parts (like swing-out hinges) with lubricant.
- Inspect the can holder for cracks or bends.
A well-maintained mount can last as long as your Jeep.
