835mm Shackle Spring – 7 Leaf to suit Millard Caravans
835mm shackle eye-to-eye spring used on Millard single axle and Tandem axle caravans.
Millard caravans and other manufacturers have used the same design spring in its caravans for over 70 years. Al-ko now stocks only a 7-leaf or 45mm wide spring.
Over time, 835mm shackle springs become fatigued and require replacement. When purchasing other generics, the leaf spring should be 8mm.
Should I replace all springs when one spring broken or flattened?
In an emergency, on holidays and stuck in an outback town, the best thing to do is to replace the broken spring and continue your journey.
At a suitable time, visit a weight bridge and weight your rig because it is likely the rig is heavier than you think.
Now your rig has the correct weight, consider replacing the other spring because it is likely to be damaged also.
You might even be surprised to learn that you need a spring upgrade becuase your existing spring is both under rated and over working.
If you need more information on the right course of action, call the experts on 0733483822 and we’ll help you though ensuring your rig is in great shape for the highway.

TIP: Our most common call for help concerns the wrong spring picked for tandem axle trailers, which usually have offset springs.
Note: Al-ko has been manufacturing a range of springs for pop-top Millard Caravans for many years. However, all springs except this genuine seven-leaf Alko shackle spring has been discontinued.
If you do not need all seven leaves, here is a tip: Remove the third leaf from the bottom, then re-insert the centre pin.
The Alko centre pin is mild steel, so do not overtighten it. The U-bolts will do most of the work clamping the spring together.
Couplemate carries good stocks of this hard-to-locate spring.
- The rear end of the spring connects to a rear hanger.
- The eye from the front of the spring attaches to a spring hanger.
- Shackle plates are used in conjunction with shackle bolts to connect the spring to the dumbjack.
The spring moves on shackle bolts plates around a rear hanger.
Enable load sharing by linking the 45mm Shackle through a “rocker” assembly in a multi-axle configuration. Load transfers from one axle that is carrying a significant percentage of the weight (crossing kerbs, etc.) to the other axle.
Why are shackle leaf springs superior to slipper springs?
- Shackle springs are less noisy on the road
- Load sharing capability
- Wear and tear from direct contact with the chassis
- The tail of the slipper is not fixed and can pop out of its housing
- Slipper springs and in particular parabolic springs twist when reversing
- Eye-to-eye springs swing on shackle bolts thereby creating less wear than standard slipper springs.
Why do some springs break prematurely or lose spring tension?
The cause is vibration fatigue, read about it here.
