Next Level Performance
September 19, 2026 • 9 min read
Your Jeep Wrangler JL is already the best snow-day rig in the driveway — but the moment you load four people, ski boots, and a weekend of wet gear inside, the cabin runs out of room fast. The fix is getting your winter cargo up on the roof. The right Jeep Wrangler JL roof rack, a sealed cargo box, and a locking ski carrier turn a cramped, foggy-windowed mountain drive into an easy one, and they keep salty slush and dripping gear out of your interior. At Next Level Performance in Tampa, FL, we build winter and overland Wranglers year-round, so we pulled the five cargo and rack upgrades below that actually earn their place on a JL headed for the snow.
Our Verdict
The ARB BASE Rack is the strongest do-it-all foundation for a winter-ready Jeep Wrangler JL.
If you want one permanent platform that carries a rooftop box, a ski carrier, and recovery gear through salt and snow, the ARB BASE Rack 61in x 51in kit is our top pick — a rigid, corrosion-resistant deck rated for roughly 220 lb of dynamic load. On a tighter budget, the Rhino-Rack Universal Ski Carrier at around $175 is the best value for ski-trip weekends. Below we compare five winter cargo upgrades that all fit the 2018–2026 Wrangler JL.
Shop Our Top Pick →Why a Winter Cargo Setup Matters on the Jeep Wrangler JL
A four-door Wrangler JL Unlimited gives you about 31.7 cubic feet of cargo space behind the second row and roughly 72.4 cubic feet with the rear seats folded — generous for a mid-size SUV, but it disappears the instant winter gear enters the picture. Ski bags, boot bags, wet jackets, chains, a recovery kit, and four passengers do not coexist. Moving cargo to the roof is the single most effective way to reclaim your interior for people and keep dripping, salt-crusted gear out of the cabin.
Winter also punishes the wrong gear. Road salt corrodes cheap fasteners, freezing rain seals zippers shut, and short daylight hours mean you are often loading and unloading in the dark with gloves on. The upgrades in this guide were chosen because they solve those specific problems: rigid platforms that carry weight without flexing, sealed and lockable boxes that keep slush out, and carriers you can operate without bare hands. Every product here fits the 2018–2026 Jeep Wrangler JL and JLU.
How We Chose These Winter Racks and Cargo Carriers
We ranked these five upgrades on the criteria that actually matter for a snow-bound Wrangler: confirmed JL fitment (or a genuinely universal mount), weatherproofing measured by real seals and IP ratings, load rating and capacity, ease of use in cold-weather conditions, and security for gear left at a trailhead or ski lodge. Price mattered too — the range here runs from about $175 to $1,819, so there is a legitimate option whether you are adding a single ski carrier or building a full roof platform. Our Tampa shop installs and services these racks, so the fitment notes below come from hands-on experience, not a spec sheet alone.

The 5 Best Winter Cargo & Rack Upgrades for the Wrangler JL
1. ARB BASE Rack 61in x 51in Kit — Best Overall Platform
The ARB BASE Rack is a full flat-deck roof platform and our top pick for a Wrangler JL that needs to do everything — carry a rooftop tent in summer and a loaded cargo box, traction boards, and a ski carrier in winter. This kit is complete: it bundles the 61in x 51in BASE Rack (part 1770020), the mount kit, a wind deflector, and full guard rails, so you are not chasing add-ons after the box arrives. ARB builds the deck around a proven internal frame, and the corrosion-resistant finish shrugs off the salt spray that eats cheaper racks over a Northern winter.
Key Specifications — ARB BASE Rack Kit
The ARB BASE Rack ships as a complete deck, mount kit, deflector, and full rail set.
Because the deck is flat and modular, it doubles as the mounting base for every other item in this guide — a cargo box up front, traction boards down one side, and a ski carrier across the bars. That versatility is why we recommend it for owners who want to build once and reconfigure by season rather than buy a new rack every spring.
What We Like
- + Rated for roughly 220 lb of dynamic load and far more static — enough for a rooftop tent
- + Complete kit: rack, mount, deflector, and full guard rails all included
- + Flat platform accepts a box, ski carrier, traction boards, and awnings on one deck
- + Corrosion-resistant finish built for salt and slush
Things to Consider
- – The most expensive option here at $1,819
- – A bare platform — you still add a box or carrier for enclosed storage
2. Thule Motion 3 XXL Roof Box — Best Enclosed Cargo Box
When you want gear fully enclosed, locked, and dry, a rooftop box beats an open platform, and the Thule Motion 3 XXL packs 18 cubic feet of glossy-black, weather-sealed space into a 91.3-inch-long shell. It is long enough to swallow skis plus a weekend of soft luggage, and its SlideLock system automatically locks the lid in place so nothing walks off at the lodge. A wing-shaped, forward-leaning nose trims drag and wind noise, and an integrated torque indicator clicks when the box is properly clamped to a Wrangler JL roof rack — no guesswork, no tools. Thule backs it with a limited warranty.
The Motion 3 XXL locks and seals skis and soft luggage away from winter slush.
For families, the Motion 3 XXL is the easiest win in this guide: it clears the cabin of bulky bags, keeps everything dry, and its aerodynamic shell limits the mpg and wind-noise penalty compared with strapping loose gear to a bare rack. Pair it with the ARB BASE Rack or your existing JL crossbars.
3. Go Rhino XVenture Hard Case 44in — Best Rugged Gear Case
For tools, recovery gear, and anything you want bombproof, the Go Rhino XVenture hard case is injection-molded from high-impact PPC thermoplastic and carries an IP67 waterproof rating — fully dust-tight and sealed against temporary immersion. An automatic pressure-equalization valve lets it vent altitude and temperature swings without breaking the seal, and the case locks. At $259.99 (down from $337.99), the long 44-inch version is a rugged, stackable box for a bed rack, roof platform, or cargo area.
IP67 sealing keeps recovery gear and tools dry through slush and immersion.
4. Go Rhino XVenture Gear Bag (Large) — Best Soft Duffel
Not everything needs a hard shell. The Go Rhino XVenture gear bag is a 13 x 14 x 22-inch (closed) duffel sewn from 12 oz waxed canvas with double-wall construction, so it is water-resistant, tough, and it looks the part. It rides inside the cabin, in the cargo area, or strapped to a rack, and it is the natural companion to the hard case for the soft gear — base layers, gloves, and boots — that does not need immersion protection. At $219.99 (down from $285.99), it is heirloom-grade luggage that will outlast the Jeep.
5. Rhino-Rack Universal Ski Carrier — Best Value for Ski Trips
If your winter mission is simply getting to the mountain, the Rhino-Rack 572 ski and snowboard carrier is the smartest $174.99 you can spend. It holds two pairs of skis or one snowboard in rubber-coated, sealed arms that will not scratch bases, clamps to most aero, square, or round crossbars, and locks to protect your gear at the lodge. It keeps snow and melt out of the cabin, mounts and removes in minutes, and stores flat in the off-season. For most Wrangler owners, this is the single best-value winter upgrade here.
The Rhino-Rack 572 carries two pairs of skis or a snowboard and locks shut.
What We Like
- + Best value in this guide at around $175
- + Holds 2 pairs of skis or 1 snowboard in soft, sealed arms
- + Locks to deter theft at the trailhead or lodge
- + Universal clamps fit most crossbars; on and off in minutes
Things to Consider
- – Skis ride exposed to the elements versus an enclosed box
- – Requires crossbars or a platform to mount to
Winter Install and Fitment Tips for the Wrangler JL
A hardtop makes roof mounting simple: full platforms like the ARB BASE Rack bolt to the hardtop with the vehicle-specific mount kit, while boxes and ski carriers clamp to crossbars. If you run a soft top, choose systems that mount to the sport bar or windshield channel instead of the roof. Before your first snow trip, confirm garage-door and clearance heights with the rack loaded — a tall cargo box adds roughly a foot of height.
Two winter-specific habits save you headaches: apply anti-seize to every mounting bolt so road salt does not weld the hardware together, and torque fasteners to the manufacturer spec, then re-check them after the first drive. Watch dynamic load — the moving-weight limit, not the parked limit — and keep the heaviest items centered and low. When ski season ends, pull the box or carrier to recover the mpg and cut wind noise; the ARB platform can stay on year-round for overland duty.
How Much Should You Budget for a Winter Wrangler Build?
Entry into roof-mounted winter gear starts at around $175 for the Rhino-Rack ski carrier — the best value if all you need is to haul skis. Rugged storage sits in the $220–$260 range for the Go Rhino XVenture bag and hard case, both currently on sale. A premium enclosed cargo box like the Thule Motion 3 XXL runs about $1,250, and a complete ARB BASE Rack platform is roughly $1,800. Several of these carry active promotions right now (the ARB platform and Rhino-Rack carrier at an extra 10% off, the Thule box at an extra 5% off), so check the live product pages for current pricing before you build your cart.
Frequently Asked Questions
Can you put a roof rack on a Jeep Wrangler JL?
Yes — the Jeep Wrangler JL and four-door JLU accept a roof rack, and a hardtop-equipped JL is the easiest to rack. Full platforms like the ARB BASE Rack 61in x 51in kit bolt to the hardtop with a vehicle-specific mount kit, while ski carriers and cargo boxes clamp to crossbars. If you run a soft top, use rack systems designed to mount to the sport bar or windshield channel rather than the roof.
What is the roof weight limit on a Jeep Wrangler JL?
Plan on roughly 100–150 lb of dynamic (moving) roof load on a hardtop JL, which is why rack makers publish their own numbers. The ARB BASE Rack is rated for about 220 lb of dynamic load on-road and far more static load when parked, so a rooftop tent or a loaded cargo box stays within spec. Dynamic load is what matters while driving; static load applies when the vehicle is stopped.
Will skis fit inside a Jeep Wrangler JL?
Full-length skis (170–200 cm) generally will not fit inside a four-door Wrangler JL without folding the rear seats, which sacrifices passenger space. A roof-mounted ski carrier such as the Rhino-Rack 572 holds two pairs of skis or one snowboard outside the cabin, and an enclosed box like the Thule Motion 3 XXL swallows skis up to about 200 cm while keeping them dry and locked.
Are rooftop cargo boxes good for winter driving?
Rooftop cargo boxes are excellent for winter because they seal gear away from road salt, slush, and moisture while freeing up cabin space for passengers. Look for a lockable box with a weather-sealed lid, like the Thule Motion 3 XXL. Expect a small mpg penalty from the added height and drag, and remove or lower the box when it is not in use to cut wind noise.
Does a roof rack hurt gas mileage on a Wrangler?
Yes, adding height and frontal area to an already boxy Wrangler will cost a few mpg, and a loaded cargo box costs more than bare crossbars or a low-profile ski carrier. In our experience the drop is usually in the single-digit-percent range at highway speed. Removing the box or ski carrier in the off-season restores most of that efficiency.
How do I keep winter gear dry and secure on a Jeep?
Use lockable, weather-rated storage: an IP67-rated hard case like the Go Rhino XVenture keeps dust and water out even in immersion, a sealed cargo box protects soft luggage and skis, and a locking ski carrier deters grab-and-go theft at the lodge. For salty climates, rinse hardware and apply anti-seize to mounting bolts so the rack comes off cleanly in spring.
