Yukon Tool Box Side Locker
Our Yukon Tool Box Side Locker transforms wasted truck bed space into secure, weather-resistant storage you can access without climbing into the bed. Engineered with heavy-duty aluminum construction and a powder-coated finish, this cab-side locker mounts flush against your truck’s side rail to keep tools, tie-downs, and recovery gear organized and protected.
The gas-assist lid opens smoothly even with gloved hands, while industrial-grade weather seals keep dust, rain, and snow out of your equipment. Whether you’re a contractor hauling jobsite essentials or an outdoor enthusiast carrying recovery straps and camp gear, this side locker gives you instant access to what you need most without sacrificing valuable bed space.
Side locker specifications & features
Aluminum Construction & Weather Protection
We build every yukon tool box side locker from .100-inch marine-grade aluminum that stands up to years of jobsite abuse and backcountry adventures. The welded seams and reinforced corner construction eliminate the flex and warping common in thinner competitor models.
Our powder-coat finish goes beyond basic paint—it bonds molecularly to the aluminum for scratch and chip resistance that outlasts traditional coatings. The industrial-grade rubber weather seal runs continuously around the lid perimeter, creating a barrier against rain, road spray, and fine dust that can damage electronics and tools.
Mounting & Truck Bed Compatibility
The universal mounting system fits most full-size pickups with 5.5-foot or longer beds, including Ford F-150, Chevy Silverado, Ram 1500, Toyota Tundra, and Nissan Titan models. We designed the bracket system to work with both capped and open bed configurations without drilling into your bed floor.
Installation takes about 45 minutes with basic hand tools—our included template ensures precise placement every time. The side locker mounts to your bed rail using stainless steel U-bolts that distribute load evenly and prevent metal fatigue. For trucks with existing crossover tool boxes, this side locker installs forward or aft depending on your access preferences.
Interior Organization & Capacity
The 48-inch interior length accommodates tools up to four feet long—perfect for levels, pry bars, breaker bars, and folding shovels. The 12-inch width fits standard socket sets, power tool cases, and recovery equipment side by side, while the 10-inch depth prevents smaller items from shifting during transport.
We deliberately designed the interior without fixed dividers so you can customize the layout with modular organizer trays or simply load larger items that need quick access. The flat bottom surface accepts adhesive-backed tool foam if you want to create custom cutouts for specific equipment.

Side Locker Installation & Compatibility Questions
The Yukon Tool Box Side Locker fits most full-size pickups with 5.5-foot or longer beds, including Ford F-150/F-250/F-350, Chevy Silverado 1500/2500/3500, Ram 1500/2500/3500, Toyota Tundra, and Nissan Titan models from 2000 to present. The universal mounting system attaches to standard bed rails without drilling into your bed floor.
For mid-size trucks like the Toyota Tacoma, Chevy Colorado, or Ford Ranger, measure your bed rail to confirm you have at least 48 inches of clear mounting space. If you have an existing crossover tool box or bed cap, the side locker typically mounts forward or aft depending on your preferred access point.
Installation takes approximately 45 minutes with basic hand tools—no drilling into your bed floor required. We include a positioning template that shows exactly where to place the mounting brackets on your specific truck model.
You’ll attach the brackets to your bed rail using the included stainless steel U-bolts, then secure the side locker body to the brackets. The kit includes all hardware, rubber isolation pads, and step-by-step instructions. Most customers complete installation solo, though having a second person helps align the locker during initial placement.
The yukon tool box side locker features industrial-grade weather seals that create a continuous barrier against rain, road spray, snow, and dust. While we design it to be weather-resistant rather than submersible, customers regularly report keeping electronics, documents, and tools completely dry through heavy rainstorms and winter driving conditions.
The seal compresses when you close the lid, creating a tight fit that blocks water entry from any angle. The recessed lock cylinder has its own rubber gasket to prevent moisture intrusion through the latch mechanism.
Yes, the low-profile design works with most tonneau covers and truck caps. The side locker mounts flush against your bed rail and typically sits low enough that soft roll-up covers, folding covers, and retractable tonneau systems clear the lid when opened.
For hard tonneau covers and truck caps, measure the clearance between your bed rail and the cover’s inside edge—you need at least 11 inches of vertical space for the side locker body. Many customers mount the locker toward the cab or tailgate to work around cap mounting hardware.
We back every Yukon Tool Box Side Locker with a limited lifetime warranty against defects in materials and workmanship. This covers the aluminum body, welded seams, powder-coat finish, hinges, and mounting brackets for as long as you own the product.
The gas strut, weather seals, and lock cylinder carry a three-year warranty against manufacturing defects. Normal wear from use, accidents, modifications, and improper installation are not covered. Register your product within 30 days of purchase to activate full warranty protection.
The reinforced lid and body support up to 75 pounds of evenly distributed cargo. This capacity accommodates complete socket sets, cordless tool collections, recovery equipment, or camping gear without stressing the mounting system or gas strut.
The mounting brackets distribute weight across your truck’s bed rail rather than concentrating stress at single points. For reference, a typical mechanic’s tool set weighs 40-50 pounds, leaving plenty of capacity for additional items.
The side locker comes with a standard rotary lock cylinder that accepts most aftermarket keyed-alike systems. Many truck accessory retailers and locksmiths can rekey the cylinder to match your existing truck cap, tonneau cover, or toolbox keys.
We also offer replacement cylinder sets through our <a href=”/accessories/”>accessories page</a> that are pre-keyed to common truck lock patterns. This lets you carry one key for all your truck storage instead of juggling multiple sets.
