Yukon Top Tool Box
Our Yukon Top Tool Box delivers professional-grade storage in a compact, accessible design. Built from heavy-duty steel with a weather-sealed lid, this top-mount box keeps your essential tools secure and organized wherever the job takes you.
We designed the Yukon top tool box for tradespeople, contractors, and DIY enthusiasts who need quick access to frequently used hand tools, fasteners, and small power tools. The gas-strut-assisted lid lifts smoothly and stays open, while the recessed paddle latches accept padlocks for theft protection. Whether mounted on a truck bed rail system or installed as a standalone unit, this box withstands the toughest job site conditions.

Steel Construction & Weather Protection
We build every Yukon top tool box from 16-gauge cold-rolled steel, then apply an industrial powder coat finish that resists chipping, fading, and corrosion. The reinforced lid frame prevents warping under heavy loads, while welded internal bracing adds rigidity to the side panels.
The weather seal system uses a continuous rubber gasket that compresses against the lid perimeter when latched, creating a watertight barrier. We’ve tested this seal in simulated rain chambers and freeze-thaw cycles to ensure your tools stay dry through seasons of outdoor use. The bottom panel features integrated drainage channels that route any condensation toward corner weep holes, preventing moisture accumulation inside the box.
Mounting & Installation Requirements
Bed Rail Compatibility
The Yukon top tool box ships with universal mounting brackets that fit most aftermarket and OEM truck bed rail systems. Pre-drilled flanges along both long edges accept 3/8″ carriage bolts, allowing you to secure the box directly to T-slot rails or drilling mounting plates.
Standalone Installation
If your truck lacks bed rails, you can mount the box directly to the bed floor using the included L-brackets and self-tapping screws. We recommend installing rubber isolation pads between the box bottom and bed surface to reduce vibration and prevent paint transfer. The low-profile design maintains rear window visibility in most full-size and mid-size pickups.
Internal Organization & Capacity
The 48-inch interior length accommodates pipe wrenches, levels, and long-handled tools without diagonal placement. We include a removable full-length tray with three divided compartments for small parts, drill bits, and fasteners—lift it out to access the deep lower compartment where you can store power tools, extension cords, and bulkier equipment.
The tray features integrated handle cutouts for easy removal with gloved hands, and the powder-coated finish matches the box exterior. Corner radius transitions prevent sharp edges from snagging tool bags or scratching equipment during loading.

Yukon Top Tool Box Buyer Questions
The exterior measures 48 inches long, 20 inches wide, and 18 inches tall. The internal storage space is 48″ L × 18″ W × 16″ D after accounting for wall thickness and the lid seal.
When the lid is fully open, plan for approximately 36 inches of vertical clearance above the box. This fits most full-size and mid-size truck beds without obstructing the rear window view.
Yes, the Yukon top tool box includes L-brackets and hardware for direct bed floor installation. You’ll drill mounting holes through the bed floor or use existing anchor points if your truck has them.
We recommend placing rubber isolation pads under the box to reduce vibration and protect your bed’s finish. The total installation typically takes 45-60 minutes with basic hand tools.
Our industrial powder coat withstands exposure to diesel fuel, motor oil, brake cleaner, and most common automotive fluids without staining or softening. We’ve tested the finish against hydraulic fluid and battery acid with no degradation.
For best longevity, wipe chemical spills promptly and avoid prolonged contact with strong acids or paint strippers. The finish is also UV-stabilized to prevent fading in direct sunlight.
The reinforced steel construction safely supports up to 200 pounds of evenly distributed tool weight. The lid can bear an additional 250 pounds when closed and latched, allowing you to stand on it to access roof racks or tie-downs.
Avoid concentrating heavy loads in one corner—distribute weight across the full interior length for best structural performance and to prevent stress on the mounting brackets.
Yes, the mounting brackets accommodate bed liners up to 1/4 inch thick. If you’re installing directly to the bed floor, the included carriage bolts are long enough to pass through most spray-in and drop-in liner materials.
For textured liners, you may need to sand small flat spots under the mounting feet to ensure stable contact. The rubber isolation pads compress slightly to conform to minor surface irregularities.
Yes, the gas struts use standard ball-socket mounting brackets that accept universal replacement units. We offer OEM replacement struts, and most automotive parts suppliers carry compatible alternatives.
The struts typically maintain full force for five years or approximately 5,000 open-close cycles. Replacement takes about 10 minutes with a flathead screwdriver to pop the sockets off the mounting balls.
The continuous rubber gasket creates a compression seal that blocks rain, snow, and most airborne dust when the lid is latched. In extremely dusty environments like unpaved construction sites, fine particles may still enter through the corner drainage weep holes.
For maximum dust protection, you can plug the weep holes with removable rubber caps when working in desert or demolition conditions, then remove the caps periodically to allow any accumulated moisture to drain.
