Trailer Jockey Wheel
A trailer jockey wheel is a height-adjustable, retractable wheel mounted on the drawbar or A-frame of a trailer, engineered to support the trailer tongue when disconnected from a towing vehicle and improve maneuverability during coupling, storage, or repositioning operations. By lifting or lowering the nose using its integrated screw or swivel bracket, the jockey wheel facilitates precise alignment with the towing hitch and eases the effort required to connect or disconnect the trailer, while its caster action allows smooth movement in any direction—ideal for tight spaces or uneven terrain. These wheels are constructed to carry a specified static nose load—ranging from several hundred kilograms on light models to over 700 kg on heavy-duty units—and feature sleeve diameters typically between 42 mm and 60 mm, ensuring compatibility with different trailer classes.
-
Trailer Coupler
A trailer coupler is a critical mechanical component that joins the trailer’s tongue to the tow vehicle’s hitch ball, enabling secure towing and effective load transfer; it must match the hitch ball size (commonly 2") and the trailer’s Gross Vehicle Weight Rating (GVWR) to ensure safe operation. Constructed from high-strength steel—often with powder or zinc coating—the coupler employs a latch mechanism (such as the patented wedge-latch design) that locks firmly over the hitch ball to maintain connection under dynamic loading. Adjustable-height couplers accommodate various towing setups, helping to keep the trailer and tow vehicle level, which is key to reducing sway and uneven tyre wear. Whether bolt-on or weld-on, the coupler’s design must comply with established safety standards, and its materials and construction influence both longevity and maintenance frequency.

Trailer Spring
Trailer springs—typically in the form of leaf springs—are engineered assemblies of curved steel plates (leaves) designed to flex under load, absorbing shocks and maintaining stability when hauling cargo over uneven terrain. A standard leaf spring pack may contain anywhere from one to seven leaves, each tempered to balance strength and flexibility. When the trailer traverses bumps or dips, the springs flatten and flex, dissipating energy and reducing stress on the frame and axle, thus preserving structural integrity and ensuring cargo remains secure. The spring’s arc shape and number of leaves directly correlate to load capacity: heavier trailers require more leaves or thicker steel, while lighter trailers can use simpler, single-leaf designs. Eye-to-eye springs are common on lighter utility trailers, while slipper-type configurations are preferred in heavier applications for their self-locating pads and streamlined footprint.
-
Trailer Axle
A trailer axle serves as the central load-bearing shaft that connects the wheels and transfers the trailer's cargo weight onto the ground, playing a fundamental role in both structural support and ride dynamics. There are primarily two axle systems: spring (leaf-spring) axles and torsion axles. Spring axles use leaf spring packs mounted beneath or above the beam, offering robust, cost-effective suspension with straightforward maintenance and parts replacement. Torsion axles encapsulate individual trailing arms and rubber cords inside a sealed tube, delivering independent suspension and smoother ride quality with fewer metal-on-metal wear points. Axles can be straight for even deck height, drop-style to lower load-leveling, or overslung/underslung depending on clearance and stability requirements. They are available in configurations ranging from single to tandem or triple axles, depending on weight distribution needs.

Trailer Brake
A trailer brake system is a vital component for any towed load, ensuring controlled deceleration, enhanced safety, and compliance with vehicle regulations. These systems are generally divided into three main types—electric (or electric drum), hydraulic, and electric-over-hydraulic. Electric drum brakes utilize an electromagnetic coil activated by a brake controller signal, forcing shoes against a rotating drum. Hydraulic brakes rely on fluid pressure generated within a surge actuator on the trailer, translating towing vehicle deceleration into mechanical force on drum or disc assemblies. Electric-over-hydraulic systems combine the responsive control of electric braking with the power of hydraulic actuation, delivering stronger and smoother stopping performance—though requiring both wiring and fluid lines.
Choosing the proper brake system depends on trailer weight, usage frequency, towing terrain, cost, and maintenance preference to guarantee optimal performance and compliance.
-
Trailer U Bolt
A trailer U-bolt is a curved fastener manufactured to precise specifications, engineered to clamp the leaf spring pack to the trailer axle and maintain suspension alignment under dynamic loads. These components are typically crafted from high-strength steel—available in raw, zinc-plated, hot-dip galvanized, or stainless finishes—to resist corrosion and maintain clamping force in environments ranging from road salt to freshwater exposure. The critical dimensions—thread diameter, inside width, and leg length—must match the axle tube size, spring width, and mount plate thickness.
Proper installation involves using torque-specified nuts, lock washers or plates, and periodic re-torque checks, as steel U-bolts stretch during initial installation or under heavy load, which may loosen the clamp over time.
-
Trailer Wheel
A trailer wheel is a specialized wheel assembly designed to support the load of a trailer and transmit forces between the axle and the road surface, which includes the rim and hub, studs, lug nuts, and sometimes an integrated brake hub. These wheels vary in diameter—common sizes range from 8″ to 16″—and are built with load ratings that must match or exceed the trailer’s Gross Vehicle Weight Rating (GVWR) to ensure safety and avoid overloading. Trailer wheels bolt to the axle hubs using standard patterns—often 4‑, 5‑, or 6‑lug—and are aligned using pilot centers or hub-centric designs to maintain proper tracking and reduce vibration. Wheels used on brake-equipped trailers may contain integrated brake drums or disc mounting surfaces, enabling braking functionality.
-
Trailer Mudguard
A trailer mudguard—or fender—is an essential protective cover mounted above the wheels to shield the trailer chassis, cargo, other vehicles, and pedestrians from debris, water, and stones expelled by rotating tires. Often made from durable galvanized steel or aluminum materials, mudguards need to resist impacts, corrosion, and ultraviolet decay. Metal versions offer robust protection and can be shaped to specific designs—single‑wheel or tandem configurations. Mudguards are engineered to comply with legal standards that dictate coverage depth and proximity to the tire to minimize spray and projection of road particles. Beyond legal compliance, they help preserve under‑carriage components by diverting salty water and gravel away from suspension parts and braking surfaces.
