Well... I picked up a set from a friend who picked them up from another friend and well, they looked fine when I put them in. After about 2~3 weeks my jeep was leaning to one side and it turned out that one leaf spring must have been originally on the tire carrier side couple owners back and well... it "wore out" to be "tweaked" (around Eye it started to do reverse sag). In any case I called up Tomken asking what can be done, can they warranty, maybe just get a replacement main or something (I wanted to pay some but expected them also to throw in some) and they really blew me off. I mean it was really odd: no chance to talk about it, no choices to make as to what can be done, the second I said I wasn't the original owner they said: sorry, bye, have a nice day. I was kind of dissapointed as IMHO leafs should not get to the point that mine got and at least they could offer me options to buy another pack at a discount or something and send those in for them to take a look at...
Anyways, I put in 3.5" RE leafs and I'm not looking back...... ANother thing with the TOmken leaf packs: get rubber bushings as the poly ones will drive you up the wall with the squeeks!
