The 2014 Silverado Crew Cab Sub Box setup transforms the extended cab into a versatile work platform by positioning a toolbox between the front and rear seats. This configuration keeps essential tools organized and protected while maintaining a broad rear seat opening for tall passengers and large gear.
Below is a structured breakdown of the most useful details for buyers and DIYers who want to understand fitment, box dimensions, and real-world usage in a 2014 Silverado Crew Cab.
| Box Material | Typical Dimensions (L×W×H) | Fit Location | Access Style |
|---|---|---|---|
| Heavy-Duty Plastic | 48–52 in L × 20–22 in W × 16–18 in H | Between front and rear seats | Top-lift lid with cross-latch |
| Steel with Powder Coat | 46–50 in L × 19–21 in W × 15–17 in H | Behind rear seat or seat-mounted track | Removable lid or hinged door |
| Aluminum | 47–51 in L × 20–22 in W × 16–17 in H | Center seat well area | Quick-release or flip-top design |
| Composite (Polymer) | 45–50 in L × 18–20 in W × 14–16 in H | Floor-mounted behind seat | Hinged lid with rubber seal |
Measurements and Fitment Details
Factory seat tracks and hump height determine how low a sub box can sit without hitting floor-mounted controls. Most 2014 Silverado Crew Cab configurations leave roughly 15 to 18 inches of vertical clearance between the seat bottom and the cab floor behind the seat.
Width is usually limited to about 20 to 22 inches, which matches the narrowest point between the inner wheelhouses and the center console. Length depends on whether seat-mounted anchors are used, with common ranges from 45 to 52 inches for full-cab-span boxes.
Tool Organization and Compartment Layout
Inside a 2014 Silverado Crew Cab sub box, layout choices affect how easily you can reach items while seated. Dividers, sliding trays, and adjustable compartments turn the toolbox into a mobile workshop instead of a single large bin.
Customizable Panel Solutions
Modular panels with adjustable slots let you use hooks, rubber grommets, and elastic holders for cables, hoses, and small parts. This approach reduces clutter and prevents tools from shifting during travel.
Integrated Tie-Down and Charging Options
Add D-rings, stake pockets, or built-in power ports to support work lights, battery maintainers, and portable air tools without digging through the box each time.
Material Choices and Durability Factors
The shell material influences weight, resistance to denting, and long-term weather protection. Steel options offer rugged strength but require anti-corrosion checks in road-salt regions. Heavy-duty plastic and composite boxes resist rust and often include UV stabilizers to reduce fading and cracking.
Aluminum frames provide a lightweight balance between strength and corrosion resistance, especially when anodized or chemically treated. In a work truck like the Silverado, the sub box endures constant loading, so material toughness and fastener quality matter more than appearance alone.
Installation and Seat-Clearance Considerations
Because the 2014 Silverado Crew Cab seats slide and recline, verify that a chosen box remains clear of seat tracks at every position. Use seat-mounted anchor plates rather than floor spikes to avoid obstructing seat adjustments or damaging upholstery.
Pair seat-mounted track systems with low-profile locking mechanisms so the toolbox lid stays accessible without interfering with rear-seat legroom. Some designs flip vertically or hinge sideways to maximize usability in tighter garages or covered truck beds.
Key Takeaways for 2014 Silverado Crew Cab Sub Box Setup
- Measure seat track travel and hump height before selecting box length and height.
- Choose between seat-mounted track systems, center floor mounts, or rear bulkhead mounts based on access needs.
- Prioritize materials that resist rust, UV damage, and denting for long-term durability in work conditions.
- Plan tie-down points, sliding trays, and power options to turn the sub box into a functional mobile workshop.
- Confirm rear-seat usability, folding ability, and cab access so the setup fits daily driving and hauling needs.
FAQ
Reader questions
Will a sub box block rear-seat legroom in a 2014 Silverado Crew Cab?
Boxes that mount in the seat well rather than the cab floor typically preserve legroom, and low-profile designs with vertical lift access reduce the impact on head and leg space.
Can I still fold the rear seat with a sub box installed?
Many center-mounted, seat-track-mounted, or low-profile floor boxes allow partial seat folding, but full 60/40 split may be restricted; check exact box height and seat hinge interference before folding.
Do I need to modify the cab wiring for a powered sub box in my 2014 Silverado?
If the box includes lights or small appliances, draw power from fused circuits or the battery with an aftermarket switch and proper relay, keeping all wiring inside protected conduit to avoid chafing.
What bed-liner or cab liner is recommended with a sub box in a 2014 Silverado Crew Cab?
Use a flexible bed liner that does not harden and a breathable cab liner to reduce moisture trapping; avoid overspray on box hinges and latches to maintain smooth operation.
