Well, I've put about 160k on my stock rear leaf springs and they have about had it. I am about to get into the market for some more springs but curious to here some insight from some of yall. I honestly won't be towing anything more than a Seadoo 3-seater jetski. I want to retain as much flex as I have with my stock springs but open to idea's where I can improve. I know of someone running 63 Chevy Springs on his double cab, just haven't had a chance to talk with him. Most likely I will always wheel at Hidden Falls (mostly rocks/crawling) , unless I got some extra cash and time.
