Important derating factor
Especially relevant, non-loading sharing tandem setups like slipper spring assembles must be de-rated by 20%.
De-rating makes allowance for occasions when most of the trailer weight is on one axle. Excess loading on the axle occurs when one wheel is parked on the gutter.
Example, trailer slipper springs with a rating of 2400kg would actually be rated on the trailer registration as 1920kg or 20% rather than 2400kg
Important to note that the hangers be installed 700mm from centre of eye to centre of the rear hanger.
Hangers installed greater than 700mm centres will cause the rear leaf to jump out under shock loading conditions like deep potholes in the road.
Finally, hangers installed closer than 700mm centres will cause the spring to lock in the rear hanger and break.
Bolts supplied are 1/2 inch. Most 6mm springs have 1/2 inch ID bushes with 22mm OD.
