Caravan and trailer slipper springs are rated at 120% of full load for all single, tandem and tri-axle sets.

Example, tandem trailer weighing 2,000kg x 120@ = 2,400kg

Axles, springs and associated equipment must rate a total of 2,400kg

Heavy duty slipper springs ratings as follow:-

  • 3 Leaf – 850kg per pair
  • 4 Leaf – 1100kg per pair
  • 5 Leaf – 1350kg per pair
  • 6 Leaf – 1500kg per pair
  • 7 Leaf – 1700kg per pair

Normally it is common practice to use 2 x 40mm Square axles on a 2000kg trailer? Wrong.

Slipper Springs do not load share, they do not transfer load across both axles.

Example, each wheel in the above example has a loading of 2,000kg / 4 wheels or 500kg per wheel.

The wheel OFF the ground is carrying zero kg.

The wheel on the ground is carrying 1,000kg, whilst the other two wheels on the ground are carrying 1,000kg.

The axle with wheels on the ground is carrying 1,500kg.

If you want your trailer to have a nice smooth ride try shackle or even better, rocker roller springs.

I noticed the shock loading on the trailer from roadside potholes not as severe on the trailer.

Although the trailer slipper springs are a good low-budget solution, however, if your budget allows considering shackle or rocker roller springs,
