Frequently Asked Questions

Should I measure my trailer spring following the curve (camber)? The best way to find a replacement spring is by measuring straight across from front eye to rear eye, starting and ending in the eye centre. 

Can I use this spring on a dual axle trailer/caravan? Yes! These springs can be used for tandem axles. If you are replacing your current springs, ensure your current springs are centred and not offset — as replacing offset springs with centred springs will change axle position.
