They don't make them, they have to buy a very large amount that isn't cost effective. That is why they are only carrying 3" springs. I haven't talked to Bill in the last month, but the last time I talked he said he had no plans on doing more 2" springs. Soo with that said if your looking for 2" RTE springs you might source used ones! Or go with a Britpart or OME.
