8mm Galvanised Slipper Spring 710mm Heavy Duty

8mm Galvanised Slipper Spring 710mm is a durable highway spring designed to withstand the rigours high-speed can inflict on suspension.

Spring specifications

  • 710mm Eye to Tail
  • 8mm left thickness
  • 9/16″ x 7/8″ x 45mm bush
  • 45mm wide
  • Free camber 110mm
  • Eye to centre bolt 350mm

Price is for one spring, 8mm slipper ratings as follows

  • 3 leaf – 425kg
  • 4 leaf – 550kg
  • 5 leaf – 675kg
  • 6 leaf – 750kg
  • 7 leaf – 850kg

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

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

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

Heavy Duty Galvanised 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 / four wheels or 500kg per wheel.

Drive your trailer onto a gutter using only one wheel and you will find the wheel on the same side is lifted off the ground.

6mm Galvanised Slipper Spring – 765mm

The wheel OFF the ground is carrying zero kg.

The wheel on the ground is carrying 1,000kg, while 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 use 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 8mm galvanised slipper springs are an excellent low-budget solution, however, if your budget allows goto shackle or rocker roller springs,

Finally, if your springs are ageing prematurely, then you may be suffering vibration fatigue. Spring fatigue occurs when your axle is undersized, causing the vibrations to travel into your spring suspension.
