Mounting a Jerry can on your Jeep TJ frees up interior space for gear without sacrificing cargo capacity. A Jeep TJ Jerry can mount is one of the best upgrades for overlanding or daily driving, giving you extra fuel or water storage right where you need it. Whether you’re hitting the trails or just want more room for camping gear, this guide walks you through everything you need to know.
You don’t need to be a mechanic to install one. With basic tools and a little patience, you can have a secure mount in under an hour. Let’s break down the options, installation steps, and pro tips to get the most out of your setup.
Why You Need A Jeep Tj Jerry Can Mount
Your Jeep TJ is built for adventure, but interior space is tight. A jerry can mount on the rear bumper, tire carrier, or tailgate frees up room for passengers and gear. It also keeps fuel or water outside, reducing fumes and spill risks inside the cabin.
Many TJ owners struggle with where to store extra fuel for long trips. The factory fuel tank is only 15 gallons, which limits range. A jerry can mount solves this by adding 5 to 10 gallons of capacity without cluttering the trunk.
Plus, it looks tough. A well-mounted jerry can gives your Jeep that classic off-road aesthetic. But function comes first, so choose a mount that fits your driving style.
Types Of Jerry Can Mounts For Jeep Tj
There are three main types: bumper mounts, tire carrier mounts, and tailgate mounts. Each has pros and cons depending on your setup.
- Bumper mounts: Bolt directly to the rear bumper. They are simple to install and keep the can low for better stability. However, they can block rear access or taillights.
- Tire carrier mounts: Attach to the spare tire carrier. They save space but add weight to the tailgate. You may need a reinforcement kit.
- Tailgate mounts: Use brackets that secure to the tailgate hinges. These are less common but work well for light loads like water cans.
Most off-roaders prefer bumper or tire carrier mounts for durability. Tailgate mounts are fine for short trips but may wobble on rough terrain.
Jeep Tj Jerry Can Mount Installation Guide
Installing a mount is straightforward. Follow these steps for a secure fit. Always check your specific mount’s instructions, but this general guide works for most kits.
Tools And Materials Needed
- Socket set and ratchet
- Torque wrench (optional but recommended)
- Drill with metal drill bits (if drilling is required)
- Safety glasses and gloves
- Anti-seize compound for bolts
- Jerry can (NATO or metal style fits best)
Step-By-Step Installation
- Position the mount: Hold the mount against your bumper or tire carrier. Mark bolt holes with a marker. Make sure it clears the tailgate and taillights.
- Drill holes (if needed): Some mounts use existing holes, but others require drilling. Use a center punch to avoid bit slippage. Drill slowly with cutting oil.
- Attach the bracket: Bolt the mount to the Jeep using supplied hardware. Tighten bolts to spec—usually 30-40 ft-lbs. Use anti-seize on threads to prevent rust.
- Secure the jerry can: Place the can in the mount. Tighten straps or locking mechanism. Test for wobble by shaking the can.
- Check clearance: Open the tailgate fully. Ensure the can doesn’t hit the bumper or spare tire. Adjust if needed.
That’s it. Most installs take 30-60 minutes. If you’re using a tire carrier mount, you might need to adjust the spare tire position first.
Common Mistakes To Avoid
- Over-tightening bolts: This can strip threads or crack the bumper. Use a torque wrench.
- Ignoring weight limits: A full 5-gallon jerry can weighs about 40 pounds. Make sure your mount and Jeep can handle it.
- Skipping lock washers: Vibration can loosen bolts over time. Use lock washers or thread-locker.
- Blocking the license plate: Some mounts obscure the plate. Use a relocation bracket if needed.
Best Jeep Tj Jerry Can Mount Options
Not all mounts are created equal. Here are top-rated choices based on durability, ease of install, and price. Prices vary, but expect to spend $80 to $250.
1. Smittybilt Jerry Can Carrier
This bumper-mounted carrier is a favorite among TJ owners. It fits most aftermarket bumpers and uses a locking pin for security. The steel construction handles rough trails. Installation is bolt-on with no drilling required on compatible bumpers.
Pros: Affordable, sturdy, easy to install. Cons: May need a bumper with pre-drilled holes.
2. Rugged Ridge Jerry Can Mount
Rugged Ridge offers a tire carrier mount that works with their spare tire carriers. It holds a standard 5-gallon can and includes a strap system. The mount is powder-coated to resist rust.
Pros: Integrated design, good for tire carriers. Cons: Requires specific carrier model.

Teraflex makes a tailgate hinge mount that’s ideal for water cans. It uses the existing hinge bolts for a clean install. The bracket is aluminum, so it’s lightweight but strong.
Pros: Lightweight, no drilling. Cons: Not for heavy fuel cans; best for water.
4. DIY Options
If you’re handy, you can build a mount using steel plate and bolts. Many forums have templates. This saves money but requires welding skills. A DIY mount can be custom-fit to your bumper.
Pros: Cheap, custom. Cons: Time-consuming, needs welding.
Tips For Using A Jerry Can On Your Jeep Tj
Once your mount is installed, use these tips to stay safe and efficient. Fuel and water storage require care, especially off-road.
Choosing The Right Jerry Can
NATO-style metal cans are best for fuel. They are durable and seal well. Plastic cans are lighter but can crack in extreme cold. For water, use a dedicated can to avoid contamination.
Always label your cans. Fuel and water cans look similar. A simple sticker or paint mark prevents mistakes.
Securing The Can Properly
Use straps or locks to prevent theft. Many mounts include locking pins. Add a padlock for extra security. Check straps before every trip—vibration can loosen them.
Also, leave some air space in the can. Fuel expands in heat. Fill to 90% capacity to avoid pressure buildup.
Weight Distribution
One full jerry can adds 40 pounds to the rear. This changes your Jeep’s balance. On steep climbs, the extra weight can affect traction. Drive cautiously until you adjust.
If you carry two cans, spread them evenly. Avoid mounting both on one side. This reduces stress on the bumper and improves handling.
Maintenance And Care For Your Mount
Your mount will face mud, salt, and rocks. Regular maintenance keeps it working. Inspect bolts monthly for rust or looseness. Re-torque if needed.
Clean the mount with a pressure washer after off-road trips. Apply a rust inhibitor to bare metal areas. If you see rust, sand it down and repaint with enamel spray.
Lubricate locking pins and hinges with silicone spray. This prevents seizing. Replace worn straps immediately—they can snap under load.
Legal Considerations For Jerry Can Mounts
Some states have laws about external fuel storage. Check local regulations. In many areas, you can carry up to 10 gallons without special permits. But some places restrict plastic cans or require spill-proof designs.
Also, ensure your mount doesn’t block taillights or license plate. Police may ticket you for visibility issues. Use a license plate relocation kit if needed.
For off-road parks, check their rules. Some require fuel cans to be secured with straps, not just bungee cords.
Frequently Asked Questions
Can I install a jerry can mount on a stock Jeep TJ bumper?
Yes, but most stock bumpers lack mounting holes. You’ll need to drill or use a bracket that clamps to the bumper. Aftermarket bumpers are easier to work with.
Will a jerry can mount affect my spare tire clearance?
It can. Tire carrier mounts may push the can into the spare. Measure your setup first. Some mounts are offset to avoid this.
How much weight can a TJ tailgate handle with a jerry can mount?
The stock tailgate is rated for about 50-60 pounds of spare tire. Adding a jerry can (40 pounds) may exceed this. Use a reinforcement kit for safety.
Can I use a plastic jerry can with a metal mount?
Yes, but plastic cans may not fit securely. Metal mounts are designed for NATO cans. Use rubber padding to prevent rattling.
Do I need a locking mechanism for my jerry can mount?
Not required, but recommended. Fuel theft happens at campsites. A lock adds peace of mind.
