The best truck cap gun rack depends on where you can mount it and whether you prefer horizontal or vertical storage. The Allen molded and metal racks are best for a suitable rear-window or wall mounting surface; the CoJo and seat-back options are better for headrest-rod mounting. Before choosing, confirm that the rack’s mounting method, available space, and firearm dimensions work with your truck cap and gear.
| Product | Best for | Storage style |
|---|---|---|
| Allen Molded Truck Gun Rack | Adjustable two-item storage | Horizontal, rear-window mount |
| Allen Rear Window Gun Rack | Balanced support from two hooks | Horizontal |
| CoJo Universal Vehicle Gun Rack | Quick, tool-free installation | Vertical, headrest mount |
| Allen Metal Gun & Bow Rack | Metal construction and dual support | Horizontal |
| Truck Gun Rack for Seat Back | Adjustable hooks for varied gear | Vertical, headrest mount |
Allen Molded Adjustable Truck Gun Rack
This molded polymer rack is best for buyers who want horizontal storage for two rifles, shotguns, bows, or hunting tools. Its hand-adjustable span ranges from 9.5 to 16.5 inches, which gives buyers a specified adjustment range to compare against their gear and intended mounting location. The product is described for rear-window or wall mounting.
The injection-molded polymer construction is presented as suitable for regular use and exposure to outdoor conditions. Choose this option if adjustability and nonmetal construction are priorities. Its listed mounting approach may not suit every truck cap: check the cap’s interior layout and the mounting surface before purchase. The product information does not provide a weight capacity or detailed mounting hardware specifications.
Allen Two-Piece Rear Window Gun Rack
This Allen rack is best for buyers seeking a horizontal two-point support system for a truck rear window or wall. One hook supports the rear of a firearm or bow, and the other supports the front. That separated support is intended to distribute the item’s weight across two points.
Choose this rack if its two-hook layout matches your available mounting area and storage needs. The product description identifies heavy-duty materials but does not specify a material type, adjustment range, or load limit. For a truck cap installation, confirm that the intended surface can accept the rack and that the hooks clear the cap’s window and interior components. It may be a poor fit if you need a headrest-mounted or vertical rack.
CoJo Universal Vertical Vehicle Gun Rack
The CoJo rack is best for buyers who want to store two rifles or shotguns vertically behind a vehicle headrest. It uses adjustable mounting hooks and is described as fitting most trucks, cars, and SUVs. The stated tool-free attachment to headrest rods is useful for buyers who want a quick setup without a separate rear-window mounting installation.
Choose this option if the vehicle’s headrest rods are the intended mounting point and vertical storage suits your space. The product is not described as a truck-cap-mounted rack, so verify the placement and clearance in your vehicle before buying. Avoid it if you specifically need a rack attached to the cap’s rear window or another fixed cap surface.
Allen Metal Gun & Bow Truck Window Rack
This Allen rack is best for buyers who prefer a metal horizontal rack with separate front and rear support points. The product information says it attaches to a truck rear window or wall and can hold firearms, bows, and tools. Like the other two-piece design, one hook supports the rear and one supports the front for balanced placement.
Consider it if you want a metal option for a compatible mounting surface. The description does not state an adjustment range or load capacity, so those details should not be assumed. Check the truck cap’s interior dimensions and mounting requirements before selecting it, especially if the cap has limited space around the rear window.
Truck Gun Rack For Seat Back
This seat-back rack is best for buyers who want three hooks for firearms, fishing rods, or other gear. It hangs from headrest posts, and the listing says the hooks rotate vertically as the seat adjusts. Each hook is specified for a 33-pound load, while adjustable silicone strips and anti-slip barbs are intended to help hold gear in position.
Choose it if headrest-post installation and adjustable hook placement fit your needs. The listing describes high-strength nylon and silicone construction and a simple hanging installation. This is a seat-back mount, not a dedicated truck-cap window rack, so it may not work for buyers who need storage in the cap itself. Check the intended gear size and mounting position before use.
Buying Guide: How To Choose A Truck Cap Gun Rack
Should you choose a rear-window rack or a headrest mount?
A rear-window rack is the closer match for buyers who want storage against a fixed surface in the cab or cap. The Allen options use rear-window or wall mounting as described in their product details. Headrest mounts, including the CoJo and seat-back designs, attach to headrest rods or posts instead. They should not be treated as truck-cap mounts without confirming that the mounting point is compatible.
How much room do you need?
Compare the rack’s stated dimensions or adjustment range with the available interior space and the size of the gear. The molded Allen rack lists an adjustable span of 9.5 to 16.5 inches. The other products do not provide a comparable range in the supplied details, so check the product listing for dimensions before ordering.
What support style works for your gear?
Horizontal two-piece designs support an item at front and rear points. Vertical headrest racks organize gear behind a seat. The seat-back model has three hooks and adjustable silicone strips, while the CoJo listing specifies storage for two rifles or shotguns. Match the rack’s stated capacity and format to the number and type of items you plan to carry.
What should you verify before installation?
Confirm the mounting surface, clearance, attachment method, and any stated load information. Do not assume that a rack fits every cap or vehicle just because it is described as universal or intended for truck windows. Secure transported equipment appropriately and follow applicable laws and the rack manufacturer’s instructions.
