Every week somebody posts the same thing in the Jeep groups: "Just picked up my JL. What should I get first?" Then 200 people answer with 200 different lift kits.
Slow down. The best first mods are the boring ones you'll use every single day: getting in and out, seeing at night, holding your phone, and protecting yourself if someone backs into you in a parking lot. The lift, the 37s, and the bumpers can wait until you've driven it for a few months and know what you actually want.
Here's the order most owners end up wishing they'd followed.

1. Running Boards (Especially for Shorter Drivers)
This is the mod new owners say they should have bought on day one. A stock JL sits high, and the factory rock rails on a Rubicon are built to take hits, not to be a step. If you or your passengers are on the shorter side, climbing in becomes a daily workout.
The fix most shorter drivers land on is a board that sits lower and sticks out farther. Two things to look for:
- Drop height. "Drop step" or "drop down" style boards put the step a few inches below the rocker. That's the difference between a comfortable step and a knee-to-chest climb.
- Depth. A wider tread gives you room for your whole foot instead of balancing on your toes. Narrow tube steps look clean but are hard to use in wet shoes.
Fitment matters. 2-door and 4-door JLs use different lengths, and Gladiators are their own size. Rubicons with factory rock rails may need the rails removed or a board designed to mount alongside them. Check the listing against your exact body style before you order.

Trade-off: low boards are the first thing to drag on a rocky trail. If you wheel hard, look at a rock slider with a built-in step instead.
2. Light Bar, Wired to the Factory Aux Switches
A 50" or 52" curved light bar across the windshield is the classic Jeep look, and it's genuinely useful on dark back roads and trails. The mistake owners make is wiring it like they would on an older Jeep, with a cheap harness and a toggle switch zip-tied to the dash.
Many JLs and Gladiators came with the factory auxiliary switch bank, the row of AUX buttons on the lower dash. If yours has it, the wiring is already run for you. JL owners on the forums report that two of the four aux circuits are rated around 40 amps and two around 15 amps, so check which switch you're using before you hook up a big bar. A typical 300-watt, 52" bar pulls roughly 25 amps at 12 volts, which belongs on one of the higher-rated circuits or on a relay. Confirm the ratings and the wire colors for your model year in the owner's manual or a factory wiring diagram before you connect anything.
No factory switches? A plug-and-play aux switch panel or a quality relay harness is the next best thing. Skip the no-name harness with a thin-gauge wire and a mystery fuse.
What you need for a windshield-mount bar:
- 52" curved LED light bar
- JL windshield light bar mounting brackets (JL and JT use their own brackets; JK brackets do not fit)
- Relay wiring harness if you're not using the factory switches
Street rule: a roof or windshield light bar is an off-road light in most states. Keep it off on public roads, and some states want it covered. If you live on the coast, put dielectric grease on the connectors; our salt-air rust prevention guide explains why corroded plugs cause half the "electrical gremlins" people chase.
3. Headlights
If your JL has the base halogen headlights, this is the single biggest upgrade for night driving. The factory halogens are fine in town and weak on an unlit highway.
The short answer: a full replacement housing with a real projector beats LED bulbs stuffed into the halogen reflector. Bulbs in a halogen bowl scatter light and blind oncoming drivers. Higher-trim JLs that came with factory LED headlights don't need this at all.

4. Dash Cam
A dash cam is cheap insurance. Parking-lot dings, someone merging into you, or a bad call at a four-way stop: footage settles the argument.
What to look for on a Jeep:
- Front and rear. A two-channel camera covers the rear-end hits that are most common in traffic.
- Hardwire option. A hardwire kit powers the camera without a cord across the dash and lets it run parking mode. A common JL trick is pulling power from the rearview mirror connector or an add-a-fuse tap.
- Low-voltage cutoff. Parking mode will drain a battery if the camera doesn't shut itself off. JLs with auto start-stop are sensitive to battery voltage, so set the cutoff conservatively.
- Heat rating. A Jeep with the top on in an Alabama summer gets hot. Supercapacitor cameras handle heat better than ones with lithium batteries.

5. Phone Mount
The JL dash has plenty of flat surfaces and almost nowhere good to put a phone. Vent clips fall out of the JL's round vents, and suction cups lose their grip in the heat.
The mounts JL owners like best bolt to the dash bezel or clip into the gap around the Uconnect screen, so the phone sits next to the screen at eye level. Look for one listed specifically for your model year range, since the dash changed with the bigger screens in later years.

6. Roof Rack (If You Actually Need One)
A roof rack makes sense if you haul a rooftop tent, kayaks, or recovery boards. It doesn't make sense just because it looks good, because it adds wind noise and hurts gas mileage on a vehicle that already gets 17 to 20 mpg.
Things to check before buying:
- Hardtop, soft top, or Sky One-Touch. These need different racks. Some mount to the hardtop, others to the body or the tub so you can still take the top off.
- Dynamic vs. static weight rating. Dynamic is what it holds while driving. Static is what it holds parked, like a rooftop tent with people in it. Don't confuse them.
- 2-door vs. 4-door length.

What Can Wait
Hold off on these until you've lived with the Jeep for a few months:
- Lift kits and big tires. They change your gearing, your speedometer, your fuel economy, and your warranty conversation with the dealer. Start with our lift kit compatibility guide and the real cost of a lift kit before you buy one.
- Steel bumpers. Heavy, expensive, and they affect your front suspension. Read our front bumper guide first.
- Tuners. Most first-year owners don't need one, and some create warranty headaches.
One thing that shouldn't wait: a basic recovery strap and a proper recovery point. Our trail recovery kit guide covers the minimum to carry.
Shopping for Someone Else?
If you're buying one of these as a Christmas gift for a new Jeep owner, the safest bets are a dash cam, a phone mount, or a recovery strap, because fitment is forgiving. Running boards, roof racks, and light bar brackets depend on the exact model, door count, and top, so confirm those first. Our Jeep gift guide by budget has more ideas and a quick way to tell a JK from a JL.
Quick Reference

|---|---|---|
| Running boards | Getting in and out every day | 2-door vs 4-door vs Gladiator; Rubicon rock rails |
| 52" light bar | Night visibility off-road | JL/JT brackets only; check aux switch amp rating |
| Headlights | Night visibility on-road | Only needed on halogen trims; buy a real projector housing |
| Dash cam | Proof after a crash or ding | Set low-voltage cutoff; start-stop is battery-sensitive |
| Phone mount | Vents and suction cups don't hold | Dash changed with larger screens; match model year |
