This Viking 1000kg Parabolic Single Leaf Spring Dacromet gives your trailer or van a straight-up 1000kg per pair capacity so you can load gear with confidence. The 78cm overall length lines up with a lot of standard hanger layouts on smaller caravans and boat trailers. The 4.5cm wide leaf keeps the axle tracking straight when you tackle corrugations or potholes with a few hundred kilos over the axle.

The spring runs a parabolic steel leaf across the full 78cm span to spread the flex and cut down on hard spots. The Dacromet coating covers the 4.5cm wide surface to help it stand up to road spray and boat ramp dunking. The 1000kg per pair rating works well on many single axle trailers that carry around 500kg per side. It is a smart buy if you want suspension gear that matches Aussie towing conditions.

Q: Is this spring sold as a single unit or as a pair?

This spring is supplied as a single parabolic leaf. The load rating of 1000kg is quoted per pair, so two springs are required to achieve that rating on an axle. When planning a new setup it is best to order two springs so both sides of the axle match. Mixing old and new springs can change ride height from side to side.

Q: Can this spring be used on boat trailers that see saltwater?

Yes, the spring includes a Dacromet finish suitable for wet environments. Dacromet is a sacrificial protective coating that helps shield the underlying steel from rust. Rinsing the spring with fresh water after saltwater use will still help extend service life. Regular checks for stone chips or damage around the 78cm length are recommended.

Q: What hanger spacing suits the 78cm overall length?

The spring suits setups built around its 78cm eye-to-tail length. Installers generally set fixed hangers and shackles to suit that overall size so the spring can work through its designed travel. Checking your existing spring length before ordering will help confirm compatibility. If your current spring differs noticeably, have a suspension specialist confirm fitment.

Q: Is this spring suited to single axle caravans only?

The spring can be used on caravans or trailers within the 1000kg per pair rating. Many smaller single axle caravans and boat trailers fall in this range. Tandem setups may use different ratings or configurations depending on total ATM and axle group design. A weighbridge reading and axle plate data will help confirm if this rating matches your trailer.
