I would suggest lurking around the Tacoma, Raptor and Overland Bound forums and look for feedback on Deaver and other progressive leaf packs. It seems to be the only way to go if you are serious about making the rear end work right for your application and needs. Blocks, lift bags, AALs, "helper springs", etc are all bandaids of a sort. I say this based on everything I've read on various off-road forums and from understanding how the rear suspension works on our trucks. I'm still on blocks and AALs and they work but I WILL be upgrading to a custom progressive pack eventually.
