Model: STK Series Stock Trailers (STK‑12, STK‑14 & STK‑16)
Built for livestock owners who value durability, simplicity, and dependable performance, the Bar‑M STK Series delivers a practical stock trailer designed to handle the demands of everyday hauling. Available in 12′, 14′, and 16′ bumper pull configurations, these trailers provide the strength and versatility needed for farm, ranch, show, and sale barn use.
At the heart of every STK Series trailer is a rugged all-aluminum frame featuring aluminum sidewall posts, aluminum roof bows, and a seamless one-piece aluminum roof. Combined with durable flooring, heavy-duty hardware, and proven axle systems, the STK Series is engineered to provide years of reliable service while remaining lightweight and easy to tow.
The stock area is designed with both livestock safety and owner convenience in mind. Full-length extruded aluminum sidewalls, high and low airflow openings, a curb-side access door, and a rear swing gate with integrated slider work together to provide excellent ventilation, easy loading, and efficient animal handling. Interior LED lighting and thoughtfully placed access points help make loading, unloading, and transportation easier in any environment.
Attention to detail continues throughout the trailer with automotive-style wiring, LED lighting, electric brakes, diamond plate nose protection, and a complete safety package designed to give owners confidence on every trip. Available upgrades allow you to customize your trailer to fit your operation, whether you’re hauling a few animals across town or managing daily ranch and farm responsibilities.
Tough, dependable, and built to work, the Bar‑M STK Series delivers the functionality, durability, and value livestock owners rely on day after day.
