Replace front coils with heavier spring rate?

Hey all, looking for some help here. I recent added a bunch of weight to my front end (300+ lbs). To get the lift back up, I have temporarily added some .5” CB shims that gives about 1” of lift while I’m waiting for my new suspension to arrive. Well, I just found out today that the new kit won’t ship until January so I’m looking to swap out the springs for now. Any idea who makes some 700# springs that will work with the stock Fox coilovers? I’ve seen Eibach and OME, but those seem to require using their struts. Any help would be great! TIA

Currently there are no application specific upgrade springs for the Pro Fox’s. Eibach is developing replacement springs for the Pro Tacoma’s but nothing for the Tundra yet.
