on my 06 prerunner I have 5100's in the front but the rear is still stock, no TSB, nothing. at first i was just going to go with 5100's in the rear too and call it good. Then I read a few things about people over extending them and tearing them apart. I was looking into the icon 1.5" leaf pack and the bilstein 5150's instead of the 5100's. has anyone ran these? would I run into the same prolem with these as I would with the 5100's?
would the 1st gen ones work on a 2nd gen?
