looks like a cheap and easy way to add a couple of inches of lift

ya there junk. those Extenders are crap. btw you still need longer stocks with those so thats $80ish then you still need an alignment with new adjustment cams thats around $100..

get coils there just about the same price and work better

They sound just like coil spacers to me, i have some 1 inch coil spacers on my 97' F150 and it works great, just dont plan on offroading cuz they will most likely fall off really quick lol.

they dont fall apart but in a few years time they start dry rotting those stud extenders are junk and are prone to brake. or you can do like i did and run longer bolts but that center bolt is a great pain in the ass to get out. and a longer bolt none are threaded long enough so you have to retap a grade 10 bolt about 5" worth.. let me tell you that is no pretty thing. done 3 sets of retaping and my die was shot i mean its toast..
