Detachable gooseneck (lowboy) trailers are designed for hauling the heaviest, most demanding loads — but their unique design brings unique repair needs. At Lone Star Trailer Services, we know these trailers inside and out, and we provide expert service on every component to keep them reliable under pressure.

What Makes a Detachable Gooseneck Trailer Unique — and How We Repair It:

• Detachable Gooseneck Assembly – The connection point is critical and often subject to cracks, wear, or hydraulic leaks. We repair and reinforce locking mechanisms, cylinders, and welds to ensure safe coupling and detachment.

• Hydraulic Systems – Gooseneck trailers rely on hydraulics to lift and detach. We repair cylinders, pumps, hoses, and valves, restoring smooth, dependable operation.

• Main Frame & Drop Deck – The lowered deck carries extreme loads, creating stress fractures, bends, and weld fatigue. We straighten, reinforce, and weld frames and crossmembers to keep the trailer structurally sound.

• Front & Rear Ramps – The loading points see constant heavy equipment impact. We replace flooring, reinforce hinges, and weld cracks to keep ramps secure.

• Kingpin & Coupler Area – This high-stress zone can wear unevenly or crack. We service and replace kingpins and rebuild coupler supports for safe connections.

• Suspension & Axles – Oversized loads push suspension systems hard. We repair and replace axles, springs, airbags, bearings, and hubs to prevent breakdowns.

• Landing Gear – Goosenecks require strong landing gear for stability during detachment. We rebuild or replace damaged gear for safe, easy operation.

• Brakes, Tires & Wheels – With heavy equipment loads, brakes and tires take a beating. We provide complete brake service and tire replacement to keep your trailer road-legal and safe.

• Lighting & Wiring – Harsh conditions damage harnesses and connectors. We repair or replace brake lights, marker lights, and wiring systems for full compliance.
