Full Beam Duratorque, 1750kg, Gull Wing, Low-Rider is a purpose-built trailer suspension designed to deliver confident handling, a lower boat-on-trailer profile, and lasting corrosion protection. Built around Trojan’s Duratorque system, this full-beam Gull Wing variant sits lower on the chassis for boat trailers while maintaining independent wheel suspension for each side, so road shocks and trailer loads are managed precisely where they matter most.

How it works

The Duratorque uses specially formulated rubber cords as the springing medium. Unlike traditional solid beam springs, each wheel is independently sprung, delivering a smoother ride and improved stability on uneven surfaces. All components are galvanised or electro-zinc plated to resist corrosion, making it a durable choice for exposed trailer applications. This model’s 1750kg capacity sits in the versatile range that suits both single-axle and tandem setups, with the tandem arrangement requiring a 25% reduction per axle.

Why this matters for you

• Lower profile for boat trailers: Gull Wing Full Beam variant keeps the boat sitting closer to the deck, improving stability and easier loading/unloading.
• Independent wheel action: Each wheel reacts to the road independently, reducing trailer sway and enhancing control on rough surfaces or when braking hard.
• Customisable braking options: Choose non-braked, hydraulic disc, or electric drum braking configurations to match your load and stopping performance needs (1750kg electric drum braked available as a dedicated option).
• Versatile capacity: Duratorque line spans 1000kg to 3000kg capacities; this 1750kg Gull Wing version is ideal for mid to heavy trailers and can be configured for full-beam or two-piece chassis widths.
• Boat trailer friendly: The gull wing design provides a lower ride height while still delivering robust support and durable, long service life.

Important ordering and configuration notes

This part is made to order with a 6–8 week lead time. When you place an order, please download and fill out the Axle Order Sheet (Adobe PDF) 197KB and return it with your specifications. Hub equipment is ordered separately to give you full control over your braking and hub configuration. For precise fitment, you’ll need to supply your required length measurement C & B as shown in the accompanying diagram.

Key specifications and options (single axle or tandem)

• Full Beam Duratorque capacities available: 1000kg – 1500kg (T101046), 1750kg non-braked or disc-braked (T101055), 1750kg electric drum braked (T101051), 2200kg non-braked or disc-braked (T101052), 3000kg non-braked, disc & electric-braked (T101068).
• Gull Wing variation supports lower trailer height and is suitable for boat trailers looking to sit closer to the deck.
• Mounting guidance – when mounted in tandem, the front axle should be braked; distance between tyres should be minimized and not exceed 150mm; ensure at least 120mm space between the top of the tyres and mudguards when new and unloaded.
• Two-piece vs full-beam – choose two-piece units to fit chassis width, or full-beam versions (with optional gull wing) tailored to your exact length and measurement requirements.
• Lead time and ordering – 6–8 week lead time; Axle Order Sheet required; hub equipment ordered separately.
