Semi Truck Cab Racks to Optimize Storage & Style

24th Jun 2025

Cab racks for semi trucks are an essential aftermarket upgrade that can protect your cargo and boost your truck’s appearance with some shiny, polished chrome.

With so many designs, mounting options, and add-on accessories to choose from, it’s hard to find the perfect fit for your rig. 

Here’s some helpful information on cab racks and a quick product roundup of some of the best-looking cab racks to consider adding to your existing setup. 

Headache racks for semi trucks can be custom fabricated (althought for a higher price point). Some of the best heavy duty commercial semi truck headache racks come from manufacturers like Merritt and Iconic.

The Clear Benefit of Cab Racks for Semi Truck Storage 

Keep your driving space decluttered. With built-in shelves, chain racks, and enclosures, you can easily manage the storage of your cargo securement chains, truck tools, and equipment. Design features like locking chain trays and split compartments also improve organization. 

Improve your safety behind the wheel. With aerodynamic designs, most cab racks promote good weight distribution and add a buffer zone between the cab and shifting cargo when you’re forced to suddenly stop. 

Add more functionality and style. Cab racks can include light brackets for work lights, beacon mounts, tarp strap holders, and grab handles for safer handling. Diamond plate pattern and polished aluminum add massive visual appeal to your trailer’s back end. 

Customize to fit your truck. Available in a variety of widths, depths, and sizes to fit Freightliner, Peterbilt, Volvo, Western Star, or Mack trucks, they come with mounting kits that make installation very flexible for various styles: single-door diamond plate units, full cabinet enclosures, drom racks with cargo decks and so much more. 

Critical Facts to Know About Cab Racks

It's always important to store your cargo within FMCSA/DOT regulations, such as like Title 49 CFR 393.

Never consider a cab rack as a part of your standard cargo security system (like brackets, chains, and straps would be). 

When you’re hauling a log or pole trailer with it, don’t use a cab rack (damage can occur). 

Don’t attach straps, chains, or other cargo securement devices directly to the cab rack (things can go wrong while cornering, decelerating or accelerating).

1x per week, inspect your cab rack for cracks or damages. Check the torque on your mounting bolts every 3 months to make sure things are stable. Cab racks are no joke. If these aren’t attached securely, it can spell injury or death. 

Common Cab Rack Accessories and Designs to Choose From

You can opt for:

  • Full enclosure (drom racks) - which looks kind of like a miniature garage door.
  • Side enclosure - two storage areas on each side.

  • Center enclosure - the storage cabinet is in the center of the rack.

  • 2 & 3 Door enclosures - offers a fuller appearance. 

  • Jail style - three cabinets with an overhead see-through space. 

Some cab racks come with a base tray. This is where you can add a tuck-away box for additional storage. 

Most manufacturers, like Merritt, incorporate grab handles for easier accessibility. 

Top-mounted light bars offer a chance to add some additional accent lighting directly onto your cab rack. Many also offer stop and turn light brackets for oval and round light fixtures. 

Short foot cab racks: this style improves the clearance when compared to the standard cab rack and offers special tray options to maximize the trailer swing clearance. 

Key Factors to Consider When Choosing Cab Racks for Semi Trucks

  • Durability and material choice (aluminum vs stainless steel)
  • Dimensions: ensuring compatibility with your truck cab (Freightliner, Peterbilt, Kenworth, Volvo)
  • Mounting options and installation simplicity (mounting kits)
  • Storage capacity: shelves, dividers, chain trays, split trays
  • Lightweight designs for maximum efficiency on long haul trips
  • Accessories compatibility: lights, hydraulic tanks, chain hangers
