I am in search of a set of springs. 2.25" ID. Length can be either 4.0" or 5.0". Spring rate 300 llbs or 325 lbs. Major manufacturers have either changed production to 6" in this weight or are on backorder until 'maybe' April. Online dealers that Drop Ship from manufacturer are not an option for this reason. I am in search of parts suppliers that actually keep stock and would have a set they could sell and ship. Any recommendations?
