Important: Spring offset is 50mm from the centre of the spring.

It is often the case that springs have failed due to the additional equipment loaded into your caravan over the years. We suggest either putting your trailer over a weighbridge to get your exact loading or upgrading from a five-leaf spring to a six-leaf spring.

Broken Springs

Springs break in only two places for specific causes, they are

• Breaks near the eye are caused by shock loading when the spring is loaded close to or over total capacity. Breakage occurs on the second top leaf just in front of the end of the third leaf
• Uneven tensioning of fishplates causes breaks near the centre bolt. Rattle guns are a significant cause of the uneven tightening of u-bolts

Spring upgrades are not uncommon on tandem setups. Spring upgrades tend to reinvigorate your caravan towing capacity to like a new standard.

60mm wide shackle is more adaptive and can withstand shock loading and twist better than 45mm springs.

Used in either tandem or single axle setups. Upgrading broken springs to the following load capacity is prevalent.
