Millard used the same spring design 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. Care when purchasing other generic; the leaf spring should be 8mm.

TIP: Our most common call for help is the wrong spring picked for tandem axle trailers. Tandem trailers usually have offset springs.

Note: AL-KO manufactures a range of springs for pop-top Millard Caravans dating back many years. However, all springs have been discontinued, except for this genuine seven-leaf Alko shackle spring.

If you do not need all seven leaves, here is a tip. Remove the 3rd 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 bolt plates around a rear hanger.

Enable load sharing by linking the 45 mm 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.

Frequently Asked Questions

What are the specifications of the AL-KO 7-Leaf Millard Shackle Spring?

Dimensions: 45mm width x 835mm length (eye-to-eye center).
Leaf Configuration: 7-leaf setup engineered for heavy-duty load distribution.
Application: Designed specifically for traditional Millard caravan chassis configurations.
Bushing: Pre-fitted with durable nylon bushes for smooth shackle bolt operation.

Should I buy genuine AL-KO or non-genuine aftermarket springs?

Choosing genuine AL-KO hardware protects your towing setup. While non-genuine springs look identical on paper, structural differences often appear under load.

Advantages of Genuine AL-KO Springs

Tested Metallurgy: Certified spring steel engineered to prevent premature sag or flattening.
Exact Deflection Rates: Matches original Millard chassis dynamics for predictable ride height and tire wear.
AL-KO Warranty: Full Australian manufacturer warranty backing for peace of mind on remote trips.

Disadvantages of Using Non-Genuine Springs

Inconsistent Eye-to-Eye Lengths: Even minor variations distort your axle alignment, causing tracking issues.
Lower Grade Steel: Higher risk of sudden brittle snapping over corrugations and heavy potholes.
Unequal Load Sharing: Mixing non-genuine springs with older setups often leads to a persistent caravan lean.
