1. ARE Z Series Walk In Door: Best Overall
In our evaluation, the ARE Z Series Walk In Door stands out for its robust aluminum construction and precise fitment. Owner feedback consistently highlights the smooth gas strut operation and tight seal that keeps out dust and moisture. The keyed lock and child safety latch provide peace of mind, meeting or exceeding typical safety standards for truck cap accessories.
However, this door is only compatible with ARE Z series caps, limiting its use for owners of other brands. If you don’t have an ARE cap or are on a tight budget, consider other options. The premium build comes at a cost that may not suit every buyer.
- Heavy-duty aluminum frame with powder coat finish resists corrosion
- Keyed entry lock with child safety latch meets industry standards
- Gas strut assist for smooth opening and closing
Pros: Excellent build quality and weather sealing; Easy to install with included hardware and instructions
Cons: Higher price point compared to aftermarket alternatives
2. Leer 100 Series Walk In Door: Runner Up
Based on owner feedback and the spec sheets, the Leer 100 Series Walk In Door offers a solid balance of weight savings and functionality. The composite frame is resistant to rust and dents, and the T-handle lock provides secure access. Many users appreciate the adjustable gas struts that let them fine-tune the opening effort.
That said, the composite material may not hold up as well under heavy use or extreme temperatures compared to aluminum. If you frequently load heavy items or live in a harsh climate, you might prefer a metal door. Also, it only fits Leer 100 series caps, so check compatibility before purchase.
- Lightweight composite frame reduces overall cap weight
- T-handle locking mechanism with keyed cylinder
- Adjustable gas struts allow customization of opening force
Pros: Good value for the quality; Lightweight design helps with fuel economy
Cons: Composite frame may not be as durable as aluminum in extreme conditions
3. Ranch Fiberglass Walk In Door: Best Budget
We researched the Ranch Fiberglass Walk In Door as a cost-effective solution for owners who need basic walk-in access. It fits a wide range of universal caps, and the fiberglass material can be painted to match. Owner feedback notes that installation is straightforward, though some trimming may be required for a perfect fit.
However, the included lock is basic and may not deter theft. The fiberglass is also more prone to cracking than aluminum if hit hard. If security and durability are top priorities, we recommend spending more on a metal door. This is best for occasional use on a budget.
- Budget-friendly option for most standard truck caps
- Fiberglass body is lightweight and paintable
- Includes basic lock and handle assembly
Pros: Very affordable; Paintable to match your cap color
Cons: Less secure lock compared to premium models; Fiberglass can crack under extreme impact
4. SmartCap EVO Walk In Door: Most Durable
In our evaluation, the SmartCap EVO Walk In Door is built to last. The combination of aluminum and steel, along with reinforced hinges, makes it ideal for heavy-duty use. Owner feedback from off-road and work truck users praises its ability to withstand rough conditions without rattling or leaking.
The main drawback is its weight, which can make installation cumbersome. It also only fits SmartCap EVO caps, limiting its market. If you don’t own a SmartCap or need a lighter option, this isn’t for you. But for those who prioritize durability above all, it’s a top choice.
- Reinforced steel hinge points for heavy use
- Dual locking latches with keyed entry
- Sealed rubber gasket prevents water intrusion
Pros: Extremely rugged construction; Excellent weather resistance
Cons: Heavy and may require two people to install; Only compatible with SmartCap EVO caps
5. SnugTop Rebel Walk In Door: Best Security
After comparing security features, the SnugTop Rebel Walk In Door leads in theft deterrence. The deadbolt and anti-pry shield make it difficult to force open, and the hidden hinge pins add extra protection. Owner feedback confirms that it feels solid and secure, even in high-crime areas.
However, the lock can be stiff initially, requiring some break-in. It also only fits SnugTop Rebel caps, so it’s not a universal solution. If security is your main concern and you own a compatible cap, this door is worth the investment.
- Integrated deadbolt lock with anti-pry shield
- Hidden hinge pins prevent tampering
- Reinforced latch mechanism
Pros: Top-tier security features; Sturdy aluminum construction
Cons: Higher cost and limited compatibility; Lock mechanism can be stiff when new
6. A.R.E. MX Series Walk In Door: Best for Work Trucks
We evaluated the A.R.E. MX Series Walk In Door for work truck applications. Its wide 24×60 inch opening makes it easy to load and unload cargo, and the heavy-duty struts are built for frequent use. Owner feedback from contractors and tradespeople is generally positive, citing convenience and solid construction.
On the downside, a few users have reported water leaks around the corners during heavy rain, though resealing usually fixes it. It only fits A.R.E. MX series caps, so compatibility is a limiting factor. If you need a large opening and own an MX cap, this is a good option, but check for potential sealing issues.
- Wider opening for easier loading of cargo
- Heavy-duty gas struts rated for frequent use
- Keyed lock with optional remote entry
Pros: Large opening accommodates bulky items; Durable struts for many cycles
Cons: Compatibility limited to MX series caps; Some owners report minor water leaks at corners
7. Leer 700 Series Walk In Door: Best Lightweight
Based on owner feedback and the spec sheets, the Leer 700 Series Walk In Door is one of the lightest options available. It is easy to operate with a single gas strut and a twist-lock. The composite material is corrosion-proof and requires little upkeep, which appeals to casual users.
However, the twist-lock is not as secure as a keyed lock, and some owners report that the composite can warp if the cap is parked in direct sunlight for long periods. If security and extreme durability are important, this door may not meet your needs. It is best for light-duty, low-risk use.
- Ultra-lightweight design for improved fuel efficiency
- Simple twist-lock mechanism
- Includes one gas strut for support
Pros: Very easy to open and close; Low maintenance composite material
Cons: Less secure lock than keyed options; Composite may warp in extreme heat
Frequently Asked Questions
What is a truck cap walk in door and why would I need one?
A truck cap walk in door is an aftermarket door installed on the rear of a truck cap (topper or shell) that allows you to access the truck bed without climbing over the tailgate. It is convenient for loading gear, camping, or accessing tools and cargo easily from the rear.
Will a walk in door fit any truck cap?
No, walk in doors are typically designed to fit specific cap models and brands. Most are custom-fit for the cap manufacturer’s own series (e.g., ARE Z Series, Leer 100 Series). Universal options exist but may require trimming or modification. Always check compatibility with your cap’s make and model before purchasing.
How secure are walk in doors?
Security varies by model. Premium doors feature keyed locks, deadbolts, and anti-pry shields, while budget models may have basic twist-locks. We recommend choosing a door with a keyed lock and child safety latch for better security. Read owner feedback to gauge real-world security.
Can I install a walk in door myself?
Many walk in doors come with installation hardware and instructions, making DIY installation possible for someone with basic tools and mechanical skills. However, some heavier doors (like the SmartCap EVO) may require two people. If you are not comfortable, professional installation is recommended to ensure proper sealing and alignment.
Do walk in doors leak water or reduce fuel economy?
Quality doors with good gaskets and proper installation should not leak. However, some budget models or poorly installed doors may develop leaks over time. Regarding fuel economy, adding a walk in door may slightly increase weight and wind resistance, but the effect is usually minimal. Lightweight composite doors have less impact than heavy aluminum doors.
Our Verdict
After researching and comparing, we recommend the ARE Z Series Walk In Door as the best overall for its combination of durability, security, and ease of use. For a more budget-friendly option, the Ranch Fiberglass Walk In Door offers solid basic functionality. Choose based on your cap compatibility and priorities.
