Horse Trailer Accessories: Must-Haves, Parts, Safety Gear & Brands

Quick Answer: The most important horse trailer accessories are safety and emergency items first: a breakaway battery, spare tire, trailer jack, lug wrench, wheel chocks, tire pressure monitoring system, first-aid kits, trailer camera, proper lighting, and ventilation. Comfort and convenience upgrades like fans, flooring, organizers, hay bags, water storage, and awnings can be added after the safety basics are covered.

In this post, we've prepared a list of must-have horse trailer accessories that equestrians everywhere must consider when buying a new or second-hand unit or modifying one they already have.

Horse trailers come in various styles and sizes, but it’s important to remember that a horse trailer is mainly a tool for horse owners to transport their equine companions safely and efficiently. The right horse trailer accessories should facilitate a more enjoyable trip for both you and your horse (or horses), whether you're spending weeks on the rodeo circuit or just taking a weekend trail ride with the family.

New to trailers? The accessories below are listed by priority. Start with safety essentials, then add comfort and convenience features as your budget allows. If you are still choosing the trailer itself, compare our bumper pull horse trailers and gooseneck horse trailers before deciding which accessories matter most.

Safety	Spare tire and jack	Prevents being stranded with horses aboard
Safety	TPMS	Warns about tire pressure or heat before blowouts
Safety	First-aid kit	Helps manage horse or human injuries on the road
Comfort	Fans and ventilation	Reduces heat stress and improves airflow
Comfort	Flooring	Improves traction and reduces fatigue
Storage	Tack organizers	Keeps equipment secure and easy to find
Convenience	Awning or shade	Helps at shows, clinics, and long trips

Safety Essentials

1. Properly fitted stalls. Horses are not all the same size, so there is no single "standard" stall that works for every horse. The most important safety factor is matching stall width, length, and height to your actual horse. A stall that is too tight forces a horse to scramble for balance and risks injury, while the right fit lets it stand, brace, and ride comfortably. Larger breeds need extra length and headroom, and smaller horses should not be forced into oversized stalls. This is where a custom build matters, since the stall is sized to your horse rather than a one-size-fits-all template.

For most riders hauling two horses, the SafeTack® 2 horse bumper pull trailer is our most popular option.

2. Emergency exits and escape doors. More than one way out matters in an emergency, especially in a multi-horse load where the front horse is hardest to reach.

For buyers comparing loading layouts, our SafeTack® slant load horse trailers are designed to open the rear entry instead of forcing horses through a narrow fixed rear tack opening.

3. Trailer brakes and a breakaway system. Electric trailer brakes matched to your tow vehicle are the foundation of safe stopping. The breakaway system runs off its own charged 12-volt battery and applies the brakes automatically if the trailer separates, holding them for at least 15 minutes. It is your last line of defense after the hitch and safety chains.

4. Tire pressure monitoring system (TPMS). Heavy trailer tires fail from slow leaks and heat you cannot see from the cab. A TPMS reports each tire's pressure and temperature in real time and warns you before a blowout. Horse-trailer-specific systems are available.

5. Spare tire and tire-changing tools. Carry a properly inflated spare, a trailer-specific lug wrench, and a way to lift one side, either a bottle jack or a drive-up tandem-axle ramp, so a flat never strands you with horses aboard.

6. Reflective tape, decals, and extra lighting. Improve visibility at night and in poor weather so other drivers see the full length of your rig.

7. Wheel chocks. Chocks stop a parked trailer from rolling, which matters most while loading and unloading on any slope.

8. Trailer cameras. A camera feed lets you watch your horses as you drive instead of pulling over, so you catch a problem the moment it starts.

9. Equine and human first-aid kit. Stock a kit for both horses and people. On the road and far from a vet, it is the difference between managing an injury and a crisis.

10. Padded dividers, chest bars, and butt bars. Padded, secure dividers and bars limit dangerous movement and cushion bumps. Double D's SafeKick wall system adds the same protection to the walls.

Protective Travel Gear for Your Horse

Beyond the trailer itself, a few pieces of gear worn by your horse can prevent the most common travel injuries.

Head bumper. A padded bumper that clips to the halter and cushions the poll, valuable for horses that throw their heads or scramble in the trailer. Double D's SafeBump Roof System is built to protect a horse's head on impact as well.

Leg protection. Shipping boots or standing wraps shield the lower legs from the knee and hock down to the coronary band. Hook-and-loop shipping boots go on faster and store more easily than traditional wraps.

Breakaway halter. A halter with a leather crownpiece or breakaway tab that releases under heavy pressure, so a horse that panics and pulls back hard cannot get trapped.

Breakaway trailer ties. Paired with a breakaway halter, ties that release under extreme force prevent neck and poll injuries if a horse sets back.

Tail wrap. Protects the tail and dock from rubbing raw against the trailer wall on longer hauls.

Fly mask. Keeps road dust and debris out of the eyes, especially in stock-type or open trailers.

Blanket or sheet. Helps regulate temperature in transit. Match the weight to the weather and avoid over-rugging, which can cause overheating.

Towing and Usability

11. Tongue jack. The front jack raises and lowers the trailer tongue for hitching and unhitching, levels the trailer front-to-back, and supports it when parked. Choose hydraulic over electric: electric-only jacks are slow, draw more power, and their gearboxes tend to fail, while hydraulic jacks are simpler and last far longer.

If towing weight and ease of handling are a top concern, start with our bumper pull horse trailers.

12. Auxiliary battery. A charged auxiliary battery powers fans, interior lighting, and other accessories for hours, including when the tow vehicle is off, and gives you a backup in an emergency.

Comfort

13. Trailer fans and ventilation. Heat stress is a safety issue, not just comfort. Aim for one fan per stall, front-mounted facing the rear, to keep air moving over the horses.

14. Quality flooring. Safe flooring with traction protects hooves and legs. Rumber, a recycled rubber-and-plastic composite board, needs no loose mats, resists moisture and rot, cuts heat transfer up to about 75 percent versus aluminum, and dampens road noise and vibration for a calmer ride. A textured surface helps grip, so scuff it lightly when new for best footing.

15. Interior LED lighting. Bright, built-in lighting makes loading and checking on horses after dark safer and easier.

16. Hay bags and onboard water for your horses. Hay bags or nets and a water supply keep horses fed and hydrated on the road. Size the water to your trip length.

Storage and Organization

17. Trailer organizers. Door organizers and built-in compartments keep tack and small gear secure and easy to find.

18. Wall grid organizers and storage caddies. Grid systems and horse-area caddies use vertical space so gear stays put without crowding your horses.

Convenience

19. Portable steps and ramps. If your trailer lacks them, steps or ramps make entering and exiting safer for you and your horse.

20. Awning and shade systems. Shade at events and rest stops protects horses and handlers from sun and weather.

How to Choose Horse Trailer Accessory Brands

Instead of looking for one “best” brand for every horse trailer accessory, match the brand to the part. Flooring, fans, hitches, windows, jacks, cameras, and tack storage all have different quality standards. Look for trailer-rated parts, corrosion-resistant materials, published specifications, warranty support, and parts that are designed for equine use rather than general cargo trailers.

Best Overall Brand

For all-around quality across the widest range of horse trailer parts and accessories, look for established manufacturers with a long track record, broad parts availability, and strong warranty support. These brands cost a little more up front but hold up better over years of hauling.

Best Brand for Trailer Windows, Doors, and Screens

Windows, doors, and screens take constant stress from wind, weather, and daily use, so prioritize brands known for durable seals, smooth latching hardware, and rust-resistant frames. Quality here directly affects ventilation, security, and how weather-tight your trailer stays.

Best Brand for Tack Storage

For tack rooms, racks, and storage hardware, the strongest brands offer secure mounting, corrosion-resistant materials, and smart space-saving designs. Good tack storage keeps expensive gear organized and protected, and it holds its value if you ever resell the trailer.

How to Choose Quality Horse Trailer Parts and Accessories

How do I determine the quality of a horse trailer part or accessory?

Look at the materials, construction, and warranty. Corrosion-resistant metals, solid welds, and reinforced mounting points signal a part built to last. Check that the accessory is rated for trailer or equine use specifically, read reviews from other horse owners, and favor brands that publish clear specifications and stand behind their products with a warranty.

How do I order a part or accessory for my horse trailer?

Start by confirming the exact make, model, and year of your trailer so the part fits correctly, since dimensions and mounting points vary. You can order through the original manufacturer, a trailer dealer, or a specialty equine supplier. For custom or hard-to-match parts, contact the trailer maker directly with your trailer's details to be sure you get the right component.

What are popular brands of horse trailer accessories?

Popular accessory brands span ventilation fans, flooring and mats, hitches and towing gear, tack storage, and safety equipment. The right brand depends on the category, so match the brand to the specific accessory rather than buying everything from one source, and prioritize those with proven durability and equine-specific design.

How to Select the Right Horse Trailer Accessories

Equipping your trailer with every available feature might be tempting, but it is usually more practical to prioritize based on your specific needs. The goal is to choose accessories that genuinely improve the trailer's safety and usefulness. Brad Heath, our in-house expert, has over 25 years of designing and manufacturing experience, so it is always worth consulting a professional about which accessories truly fit your needs.

Ensure proper ventilation. Choose a trailer with strong ventilation, or add extra fans, to keep the air in the horse area fresh.

Prioritize flooring. Check for non-slip mats or composite flooring. If the trailer lacks them, add one, since it prevents slipping and gives horses a firm grip.

Insulate and pad. Pay for wall and roof insulation and interior padding where available, to help horses cope with heat and avoid bruises.

Reinforce dividers. Install better or additional dividers that secure the horse well without creating a confined space or risk of injury.

Opt for extra lighting. A well-lit interior helps horses stay calm and makes loading and unloading easier after dark.

Equip for extended travel. For longer journeys, consider extra water tanks, a hay rack, an auxiliary battery, and solar panels to make the trailer more self-sufficient.

Maximize storage. Add tack racks, hooks, saddle holders, and storage caddies to keep gear organized and secure.

Safety first. Build a full safety kit: a spare wheel, a hydraulic or electric jack, a breakaway system, extra trailer ties, and cameras in the horse area.

Must-Have Horse Trailer Accessories: Frequently Asked Questions

What are the most important horse trailer accessories for safety?

The most important safety accessories are a working breakaway system, charged breakaway battery, spare tire, trailer jack, lug wrench, wheel chocks, first-aid kits, trailer lights, reflective tape, trailer camera, and a tire pressure monitoring system.

What horse trailer accessories should I buy first?

Start with safety items first, including brakes, breakaway system, spare tire, jack, wheel chocks, TPMS, first-aid kits, lights, and ventilation. Add comfort and storage upgrades after the trailer is safe and road-ready.

Can you leave the trailer fans on when the engine of the tow vehicle is not running?

Yes, you can, but only when you have a charged auxiliary battery to power them. The latter accessory provides energy for hours, even over long distances when the tow vehicle is not running.

What should I carry in my horse trailer?

In your horse trailer, you should carry essential items such as:

• Fresh water and a water tank for your horses

• Hay or feed for your horses

• Basic tools like a hammer, screwdriver, and utility knife

• Duct tape for temporary repairs

• A first-aid kit for both humans and horses

• Shavings or bedding for your horse's comfort

• A trailer-specific lug wrench and a hydraulic jack or Jiffy Jack for changing tires

• Trailer organizers to keep your tack and equipment organized

• A spare tire for your trailer

• A trailer camera system for monitoring your horses during transport

• Trailer fans for proper ventilation and temperature control

How many hours a day can you trailer a horse?

Many horses can handle 8 to 10 hours of trailer travel in a day, but long trips should include rest stops for water, monitoring, and recovery. For extended travel, overnight stops may be safer and less stressful.

Should I put bedding in the horse trailer?

Yes, adding bedding to your horse trailer is recommended for a few reasons:

• Bedding, such as shavings or straw, helps to absorb urine and moisture, keeping the trailer floor cleaner and drier.

• It provides cushioning for your horse's hooves, making the ride more comfortable and reducing the risk of slipping.

• Bedding can help reduce the noise and vibration inside the trailer, which can make the journey less stressful for your horse.

• Make sure to choose appropriate bedding materials that are non-toxic and dust-free to ensure your horse's comfort and health during transportation.
