send an email to primitive racing they should know.
 
Almost a week an no response from them,
Local suppliers have none of that info in the catalogues or through their wholesalers
 
Sounds right - my Kings extra-HD are 250 lb/In (corrected)
 
so they compress 250 feet for every pound..... (ft/lb)

think we need to establish some units for measurement.
I reckon it's more likely lb/In

250lb/in = 9.84lb/mm = 4.46kg/mm (same as pedders)

but I suspect the SH would be stiffer than the SG
 
There are certainly some very odd combinations of units in common use.

It took me a while, but I finally figured out that gas strut pressures are measured in Newton centimetres^2! :confused: :shrug:
 
Directly from Kings (Finally)
Front KSFS-55 290lb/In = 5.2kg/mm

Rear KSRS-56 250lb/In = 4.46kg/mm
KSRS-57 250lb/In

Directly from Pedders
Front 230022 4.46kg/mm
Rear 230023 4.32kg/mm

Given the slightly higher average rate of the Kings and their newer progressive rate design, I might actually give them a go.
I've not liked Kings in the past due to harshness, but that's a good 6+ years ago and things might have changed.
And for over $100 cheaper a set than the Pedders for springs alone, it's hard to go past them.

Seems this is about the best deal around for a complete set with KYB's too
