Switching from a soft top to a hardtop on your Jeep requires the right mounting hardware and wiring connections. The short answer to the question can you put a hardtop on a soft top jeep is yes, but it is not a simple swap. You need to understand the differences between soft top and hardtop mounting systems, wiring for rear defrost and wipers, and storage for the soft top.
Many Jeep owners love the open-air feel of a soft top in summer but want the security and insulation of a hardtop in winter. The good news is that most Jeep models are designed to accept both tops. However, a soft top Jeep often lacks the hardware that a hardtop needs to latch securely.
This guide walks you through everything you need to know. We cover compatibility, required parts, installation steps, and common mistakes. By the end, you will know exactly what your Jeep needs to make the switch.
Can You Put A Hardtop On A Soft Top Jeep
The answer is a definitive yes for most Jeep Wrangler models, including the TJ, JK, and JL. The same applies to Jeep Gladiator trucks. The body and roll bar structure are identical whether your Jeep came with a soft top or a hardtop from the factory. The difference lies in the mounting points and electrical connections.
Soft top Jeeps typically come with a simpler tailgate bar and door surrounds. Hardtop Jeeps have additional brackets and a different rear window seal. If you are adding a hardtop to a soft top Jeep, you will need to install the proper mounting hardware. This includes the front header brackets, side brackets, and rear liftgate brackets.
Do not assume your Jeep has all the holes and threads ready. Some soft top models may have plastic plugs covering the mounting points. You will need to remove these plugs and install the correct bolts or nutserts. Check your specific year and model for exact requirements.
Compatibility By Jeep Model
Not all hardtops fit all Jeeps. You must match the hardtop to your Jeep’s model year and body style. Here is a quick breakdown:
- Jeep Wrangler TJ (1997-2006): Hardtops from other TJs fit directly. You need the mounting hardware kit.
- Jeep Wrangler JK (2007-2018): Two-door and four-door hardtops are different. A two-door hardtop will not fit a four-door JK Unlimited.
- Jeep Wrangler JL (2018-present): Same rule applies. Two-door and four-door hardtops are not interchangeable.
- Jeep Gladiator JT (2020-present): Uses a unique hardtop that is not compatible with Wrangler hardtops.
If you are buying a used hardtop, always verify the model year. A hardtop from a 2012 JK will not fit a 2020 JL without modifications. Measure the width and length of your Jeep’s tub before purchasing.
What Hardware Do You Need
Your soft top Jeep likely came with the following items missing or different:
- Front header brackets that attach the hardtop to the windshield frame
- Side brackets that secure the hardtop to the roll bar
- Rear liftgate brackets for the tailgate
- Bolts, washers, and nutserts for mounting
- Wiring harness for rear defroster and wiper (if your hardtop has them)
You can buy a hardtop installation kit from Mopar, Bestop, or aftermarket suppliers. These kits include all the brackets and hardware. Expect to pay between $100 and $300 for a complete kit, depending on your Jeep model.
Some Jeeps have the wiring harness already tucked behind the roll bar. Others require you to run new wires. Check your Jeep’s wiring diagram before starting.
Step-By-Step Installation Guide
Installing a hardtop on a soft top Jeep is a straightforward job if you have the right tools. You will need a socket set, screwdrivers, a torque wrench, and possibly a drill for nutserts. Allow yourself a full afternoon for the first installation.
Step 1: Remove The Soft Top
Start by taking off your soft top completely. This includes the fabric, bows, door surrounds, and tailgate bar. Store these parts in a clean, dry place. If you plan to switch back to the soft top in summer, keep all hardware organized.
Remove the soft top door surrounds carefully. They may have screws or clips holding them to the roll bar. The tailgate bar usually unbolts from the tub. Set everything aside.
Step 2: Install Mounting Brackets
Now you need to install the hardtop mounting brackets. Begin with the front header brackets. These attach to the windshield frame above the sun visors. Your soft top may have plastic covers here. Remove them and install the brackets using the provided bolts.
Next, install the side brackets on the roll bar. These brackets hold the hardtop’s side windows in place. They typically bolt into existing holes on the roll bar. If your Jeep does not have threaded holes, you may need to install nutserts.
Finally, install the rear liftgate brackets. These go on the tailgate hinge area. They provide a latch point for the hardtop’s rear glass. Make sure they are aligned correctly before tightening.
Step 3: Wire The Hardtop
If your hardtop has a rear defroster and wiper, you need to connect the wiring. Most hardtops come with a pigtail harness. Locate the corresponding connector in your Jeep. It is usually behind the rear roll bar or under the rear seat.
If your Jeep did not come with a hardtop from the factory, the connector may be missing. You will need to splice into the rear wiper and defroster circuits. Use a wiring diagram for your specific model. Connect the ground wire to a clean chassis point.
Test the defroster and wiper before installing the hardtop fully. It is easier to fix wiring issues with the top off.
Step 4: Lift And Secure The Hardtop
Hardtops are heavy. A factory hardtop weighs around 150 to 200 pounds. You will need at least two strong people or a hoist. Lift the hardtop onto the Jeep’s tub carefully. Align it with the front header brackets and the side brackets.
Lower the hardtop slowly. Make sure the weatherstripping seats properly against the tub. Once in place, install the bolts at the front header. Then bolt the side brackets to the hardtop. Finally, latch the rear liftgate to the tailgate brackets.
Tighten all bolts to the manufacturer’s torque specifications. Overtightening can crack the fiberglass or strip threads.
Step 5: Test Fit And Adjust
Close all doors and the rear liftgate. Check for gaps or misalignment. The hardtop should sit flush with the body. If you see large gaps, loosen the bolts and adjust the top’s position. Tighten again once aligned.
Test the rear wiper and defroster again. Make sure the liftgate opens and closes smoothly. If the liftgate is hard to close, adjust the latch striker.
Common Mistakes To Avoid
Many people rush the installation and end up with leaks or rattles. Here are the most common errors:
- Skipping the wiring check: Always test electrical connections before bolting the top down.
- Using wrong bolts: Hardtop bolts are specific. Do not use soft top bolts as they may be too short.
- Forgetting weatherstripping: Replace old or cracked weatherstripping on the tub and hardtop.
- Not torquing bolts: Loose bolts cause rattles and wind noise.
Another mistake is assuming the hardtop will fit perfectly without adjustment. Every Jeep tub is slightly different. Take time to align the top properly.
Cost And Time Considerations
Adding a hardtop to a soft top Jeep involves costs beyond the top itself. Here is a rough breakdown:
- Used hardtop: $800 to $2,000 depending on condition and model
- New hardtop: $2,500 to $4,000 from Mopar or aftermarket brands
- Mounting hardware kit: $100 to $300
- Wiring harness (if needed): $50 to $150
- Hoist or lift system: $100 to $300 (optional but recommended)
Installation time is about 2 to 4 hours for a first-timer. If you need to install nutserts or run new wiring, add another hour. Plan for a weekend project if you are not experienced.
Pros And Cons Of Switching To A Hardtop
Before making the switch, consider the trade-offs. Hardtops offer better insulation, security, and noise reduction. They also hold their value well. However, they are heavy and difficult to remove alone. Soft tops are lighter and easier to take off but are less secure and noisier.
If you live in a cold climate, a hardtop is almost essential. The heater works better, and you will not have as much wind noise. In warm climates, a soft top allows you to enjoy open-air driving more easily.
Some owners keep both tops and switch seasonally. This requires storage space for the top not in use. A hoist in your garage makes swapping much easier.
Frequently Asked Questions
Can I install a hardtop on a Jeep that never had one?
Yes, as long as you install the correct mounting hardware. Most Jeeps have the necessary body structure. You may need to add nutserts for the brackets.
Do I need to modify my soft top Jeep for a hardtop?
Minor modifications may be needed. You might have to drill holes for nutserts or run new wiring. No major structural changes are required.
Will a hardtop from a different Jeep model fit mine?
Only if the model and body style match. A two-door hardtop will not fit a four-door Jeep. Always check compatibility before buying.
Can I use my soft top door surrounds with a hardtop?
No. Hardtops use different door surrounds or no surrounds at all. You will need hardtop-specific door surrounds if your hardtop requires them.
How do I store my soft top when using a hardtop?
Store the soft top in a clean, dry area. Fold it carefully to avoid creases. Keep all hardware in a labeled bag for easy reinstallation.
Final Tips For A Succesful Swap
Take your time during installation. Rushing leads to leaks and misalignment. Use a helper to lift the hardtop to avoid injury. If you are unsure about wiring, consult a professional or a Jeep forum for your model.
Check all weatherstripping before installing the hardtop. Replace any that is cracked or compressed. This prevents water leaks and wind noise. Apply a silicone lubricant to the seals to help them seat properly.
After installation, drive the Jeep for a few days and check for rattles. Tighten any loose bolts. The hardtop may settle slightly after a few heat cycles. Re-torque the bolts after a week.
Remember that a hardtop adds weight to the roof. This raises your center of gravity slightly. Be cautious when off-roading or cornering hard. The handling difference is minor but noticeable.
Switching from a soft top to a hardtop is a rewarding upgrade. It makes your Jeep more comfortable in bad weather and more secure when parked. With the right hardware and a little patience, you can complete the swap in a weekend.
If you plan to switch back and forth seasonally, invest in a hoist. It makes the job much easier and prevents damage to the hardtop. Store your soft top properly to extend its life.
Ultimately, the answer to can you put a hardtop on a soft top jeep is yes, and the process is straightforward. Follow the steps in this guide, and you will enjoy a quieter, warmer, and more secure Jeep all year round.
