they would work for uppers, hell they would even work for lowers, they just ware alot faster. so all the time and effort put into a 4-link and your now comited to keep using the same old crappy HIEM body's. just spend a little more money on some better links and insteed of changing them every seasion ( or what ever ) your now going to get some life out of some quality hardware ( a few years probally ).
im on two years now with my Q1A HIEMS and there still nice and tight. cost was 24.00 dollars each and i made my own bungs.
anyrate spend the money and you wont have to worry about breaking or replacing them alot.
