im sitting here looking at possibly ordering a couple sets and im trying to figure out what actually goes bad in these. the only thing that comes to my mind is the o rings. i cant really justify ordering new ones if i can just do the o rings and call it a day

 

The stock dummy plugs and standpipes do not have a Teflon backer on the orings, the new ones do, this backer makes a huge difference on how strong they are. you can get the complete set of dummy plugs and the standpipes in one kit for $102 from Tousley Ford.
