Shop Semi Truck Safety Parts & Accessories

Stay prepared with essential emergency equipment for your semi truck. We stock heavy-duty truck safety accessories and parts needed to ensure your commercial vehicle meets strict FMCSA and DOT regulations. Made to be durable and with universal fitment across semi-truck make/models, adding the right aftermarket safety hardware can prevent out-of-service violations with proactive maintenance.

Critical Safety Parts for Air Brakes & Pneumatic Components

Support your rig’s stopping power and stay DOT compliant with aftermarket semi truck air dryers and cartridges, control valves to regulate flow between the tractor and trailer, and air pressure monitoring systems for real-time, accurate reads on system pressure.

Secure Tractor-Trailer Hookups

Secure your back of cab setup with coiled lines, gladhands, and organizational support hardware, like pogo sticks and stainless-steel airline box backplates.

Roadside Emergency Compliance Equipment

Explore a wide selection of FMCSA regulation-backed compliance equipment like fire safety products, hazard management items like duo-flip placard holders to label toxic materials, or DOT-C2 reflective tape with self-adhesive reflectors to ensure safety during roadside inspections and emergency repairs. You can also find a variety of maintenance hardware, like brass compression fittings or nylon wire ties, and professional supplies, like respirator masks for detailed paint or polishing work.

Tractor-Trailer Electrical System & Wiring Setup

Find everything you need to properly connect and power the trailer’s lights and ABS system with aftermarket cables and cords, including 7-way Green ABS coiled cables, and straight cable assemblies. Organize your 12- to 14-gauge electrical wire with bulk wire rolls. Quickly replace damaged ABS sensors (straight and 90-degree) in various lengths (18" to 96") and maintain the Anti-lock Braking System's functionality.

Frequently Asked Questions About Universal Safety

What kinds of products are included in this category?

This category covers general safety equipment and accessories used in and around semi-trucks, such as warning triangles, road flares, fire extinguishers, first aid kits, wheel chocks, safety vests, and similar items that help drivers stay prepared for roadside emergencies and everyday safety needs.

Will these safety items meet DOT requirements?

Many of the items in this category, such as warning triangles and fire extinguishers, are designed to align with common DOT expectations for emergency equipment. However, requirements can vary by state, vehicle type, and cargo, so we recommend checking current DOT regulations or consulting your fleet safety officer to confirm a specific product meets the requirements for your operation.

Are these products universal, or do they fit specific truck makes and models?

Because these are general safety accessories rather than vehicle-specific parts, most items are designed to work across different truck makes and models. Mounting brackets or storage cases, where applicable, are typically made to fit a wide range of cabs, but we suggest checking individual product listings for any size or mounting details before ordering.

How should I store and maintain this equipment in my truck?

Safety equipment should be stored somewhere easily accessible in an emergency, such as under the seat, in a door pocket, or in a dedicated storage case. Items like fire extinguishers and first aid kits should be checked periodically for expiration dates, pressure levels, or general wear, and replaced or restocked as needed to make sure they are ready to use when needed.

How often should I replace or restock these safety items?

This depends on the specific product. Fire extinguishers usually have a gauge or indicator showing when they need to be serviced or replaced, first aid kits should be restocked after use or when supplies expire, and reflective triangles or flares should be inspected regularly for cracks, fading, or damage. Checking your equipment during routine truck inspections is a good habit to help keep everything ready for use.
