Pro Tip: It is not uncommon to see denso tape wrapped around springs on commercial fishermen trailers. We have seen Denso tape on trailer springs last 20 years. However, many buyer prefer to buy Galvanised springs. 

45mm wide boat springs, 6mm leaf thickness are suitable for metropolitan travel.

45mm x 6mm slipper springs trailer springs are suitable for metropolitan travel. Spring twisting can occur due to a combination of load centre of gravity, weight, cornering and shock loading caused by badly maintained roads.

Slipper Spring Derating

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

Why de-rate trailer slipper springs?

  • Normally it is common practice to use 2 x 40mm Square axles on a 2000kg trailer? Wrong.
  • 6mm 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.
  • Mount a gutter using only one wheel and you will find the wheel on the same side is lifted off the ground.

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, consider buying shackle or rocker roller springs.
