Christo and I were talking at Moab and he told me the ARB load specs for the Med and Heavy springs are the same, its just the heavies are longer. He said it mighty be a typo, but thats what the specs say. I was talking to him about changing the springs when I get a winch. I sent ARB an e-mail with the following question:
I currently have your medium lift springs on my 80 series Land Cruiser. I was going to switch to Heavies when I install a winch on my ARB. Looking at the two specifications, they seem to have the same load specs, but the Heavies are just longer. Can you confirm this. Why wouldn't a 1 inch spacer added to your medium springs give me the same performance?
This is their response:
You are exactly correct. The OME850 and OME851 have an identical spring rate, however the OME851 is 20mm taller than the OME850.
We offer 10mm polyurethane spacers than can be used on top of the coils for additional height. The Aussies refer to these as trim packers.
Our suspension book says use a maximum of 2 trim packers per coil. You could also use a 1" spacer to get the same result.
I know Nakman took this approach, but someone here (can't remember who) told me not to because of the load rating. Well, the load rating is the same.
