Hauling gear in your Jeep Gladiator stays dry and secure with a bed cap that fits flush against the cab. Finding the best bed cap for Jeep Gladiator can feel overwhelming with so many options on the market. You need a cap that matches your truck’s rugged look while offering real protection for your cargo.
Bed caps, also called truck toppers or camper shells, turn your open bed into a locked, weatherproof storage space. They are perfect for camping trips, work sites, or daily commutes. The right cap adds versitility without ruining the Gladiator’s off-road capability.
This guide breaks down the top picks, key features, and installation tips. You will learn what matters most when choosing a cap. Let’s get straight into the best options avalable today.
Best Bed Cap For Jeep Gladiator
The Jeep Gladiator has a unique 5-foot bed that is shorter than most trucks. This means not all standard bed caps will fit. You need a cap designed specifically for the Gladiator’s dimensions and mounting points.
Below are the top-rated bed caps that offer the best balance of durability, style, and functionality. Each one has been tested by owners and reviewers for real-world use.
1. Leer 100XR Fiberglass Cap
Leer is a trusted name in truck caps, and the 100XR is a top contender for the Gladiator. It features a sleek, low-profile design that follows the cab’s roofline. The fiberglass construction is tough and resists dents and scratches.
- Material: Fiberglass with a gel-coat finish
- Weight: Approximately 120 pounds
- Key features: Tinted side windows, carpeted headliner, interior dome light
- Price range: $2,500 – $3,200
This cap uses a clamp-on mounting system, so you do not need to drill into your truck bed. It seals tightly against the cab with a rubber gasket. Owners report no leaks even in heavy rain. The rear door opens with gas struts and locks securely.
One downside is the weight. At over 100 pounds, you may need a helper for installation. The fiberglass can also crack if you hit a low tree branch on the trail. Still, for daily driving and light off-roading, it is a solid choice.
2. ARE Z Series Cap
ARE (A.R.E.) is another premium brand known for custom fit and quality. The Z Series cap offers a modern look with a contoured shape that matches the Gladiator’s lines. It comes with a limited lifetime warranty on the shell.
- Material: Hand-laid fiberglass
- Weight: 130 pounds
- Key features: LED interior lighting, sliding front window, remote locking
- Price range: $2,800 – $3,500
The Z Series includes a sliding front window that opens to the cab. This is great for passing long items through or just chatting with passengers. The remote lock feature lets you lock and unlock the cap from your key fob.
Installation is straightforward but best done by a profesional. The cap uses a track system that bolts into the bed rails. Some owners mention the paint color may not perfectly match the factory finish, so order a color sample first.
3. SmartCap EVO Adventure Cap
If you want a modular cap that can adapt to different needs, the SmartCap EVO is worth a look. It is made from lightweight aluminum and composite panels. This makes it much lighter than fiberglass caps.
- Material: Aluminum frame with composite panels
- Weight: 85 pounds
- Key features: Removable side panels, roof rack rails, lockable storage
- Price range: $3,000 – $4,000
The EVO’s side panels can be removed to create an open-air feel. You can also add accessories like a roof tent or gear baskets. The aluminum frame is strong enough to support up to 300 pounds on the roof.
This cap is pricier than fiberglass options, but the modularity is unmatched. It is also easier to install alone because of the lighter weight. Some users note that the composite panels can scratch easier than fiberglass.
4. RSI SmartCap EVO Sport
RSI (Rugged Style Innovations) offers the EVO Sport, a simpler version of the Adventure cap. It keeps the aluminum frame but has fixed side panels. This reduces cost while maintaining strength and versitility.
- Material: Aluminum frame with fixed composite panels
- Weight: 80 pounds
- Key features: Integrated roof rails, T-slot mounting system, lockable handles
- Price range: $2,500 – $3,200
The EVO Sport is a good middle ground if you want the durability of aluminum but do not need removable panels. The T-slot system on the roof lets you attach racks, lights, or awnings easily. It also has a low profile that looks great on the Gladiator.
One thing to consider is that the composite panels are not as impact-resistant as fiberglass. If you often drive through dense brush, a fiberglass cap might be better. But for most users, the EVO Sport offers excellent value.
5. Bestop Supertop Classic
Bestop is famous for Jeep soft tops, and their Supertop Classic is a soft bed cap. It is not a hard shell, but it provides weather protection and a lower price point. It is ideal for those who want flexibility and easy removal.
- Material: Marine-grade vinyl with zippered windows
- Weight: 45 pounds
- Key features: Foldable design, quick-release mounting, storage bag included
- Price range: $800 – $1,200
The Supertop Classic can be folded down when you need full bed access. It installs with a clamp system that takes about 30 minutes. The vinyl material is UV-resistant and holds up well in sun and rain.
Security is lower than hard caps since the vinyl can be cut. Also, the zippered windows may leak in heavy storms. But for occasional use or budget-minded owners, this is a great option.
Key Features To Consider
Not all bed caps are created equal. Here are the most important factors to weigh before buying.
Material And Durability
Fiberglass caps are heavy but very strong. They resist dents and can be painted to match your truck. Aluminum caps are lighter and rust-proof but may dent easier. Soft caps are light and cheap but offer less protection.
Think about how you use your Gladiator. If you off-road hard, fiberglass or aluminum is better. If you just need occasional cover, a soft cap works fine.
Weight And Installation
Heavier caps (over 100 pounds) usually require two people to install. Lighter caps (under 90 pounds) can be done solo. Most caps use clamp-on systems that do not require drilling. Some use bolt-on tracks that are more secure.
Always check the installation instructions before buying. Some brands offer professional installation for an extra fee. This can save you time and hassle.
Weather Sealing
A good bed cap should keep water, dust, and snow out. Look for caps with rubber gaskets around the cab and tailgate. Some caps have a sliding front window that helps with airflow and reduces pressure.
Read reviews about leaking issues. Even premium caps can leak if not installed correctly. A little silicone sealant can fix most gaps.
Security Features
Lockable handles are standard on most caps. Some offer remote locking that integrates with your truck’s key fob. For extra security, choose a cap with a reinforced locking mechanism.
Soft caps are less secure because the vinyl can be cut. If you store valuables, a hard cap is the better choice.
Compatibility With Accessories
Many caps have roof rails or T-slot channels for mounting racks, tents, or lights. Check if the cap you want supports your planned accessories. Some caps also have interior lighting or carpeted headliners.
If you plan to sleep in the bed, look for caps with a high enough interior height. The Gladiator’s bed is about 19 inches deep, so a cap adds roughly 20-24 inches of headroom.
Installation Guide
Installing a bed cap on your Gladiator is a DIY-friendly job for most people. Follow these steps for a secure fit.
- Clean the bed rails thoroughly. Remove any dirt, wax, or debris.
- Position the cap on the bed, centering it left to right. Use a helper for heavy caps.
- Align the cap’s front edge with the cab. There should be a small gap (about 1/4 inch) for the rubber gasket.
- Attach the clamps or brackets to the bed rails. Tighten them evenly, but do not overtighten.
- Check the seal between the cap and cab. Adjust the cap position if needed.
- Tighten all clamps to the manufacturer’s torque spec. Re-check after a few days.
- Test for leaks by spraying water around the edges. Apply silicone sealant to any gaps.
Most caps come with detailed instructions. Watch a few YouTube videos specific to your model before starting. It usually takes 1-2 hours for a first-time installation.
