60mm x 705mm Caravan Spring fits Jayco Caravans

60mm caravan spring fits Jayco. It is expected to use replacement 705mm Shackle Springs on Jayco and other manufacturers’ tandem setups.

TIP: Cut off burred U-bolts with an angle grinder. The best place to cut old U-bolts is on the bend. Then, you only need one cut per u-bolt.

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

  • 705mm Eye to Eye.

Spring failures often occur due to the additional equipment loaded into your caravan over the years. We suggest putting your trailer over a weighbridge to get your exact loading or upgrading from a five-leaf spring to a six-leaf spring.

Upgrade Tips

  • Upgrade by one leaf if your springs have flattened
  • Maximum compression is 50mm
  • If in doubt, get a weighbridge certificate
  • Old spring may be flat and measure longer than usual

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. They tend to reinvigorate your caravan’s towing capacity to 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.

705mm x 60mm springs are available in the following configurations:

  • 5 Leaf – 500kg per spring or 1000kg per tandem kit
  • 6 Leaf – 750kg per spring or 1500kg per tandem kit.
  • 7 Leaf – 850 kilograms per spring or 1700kg per tandem kit.
