I’ve had bones hard in my 5.8ti for a year or so, almost ground to the axle but bushings are holding up fine.
Tried mediums before but they felt too loose compared to stock so I went with hard and it felt fine.
I think the Bones hard bushings seem to hold up a lot better than the mediums and softs too. Just have way too many of them with blown out cores or even the bushing just splits around the core.
They actually wear in really well too, given they are so stiff when new, but after a few solid sessions, they feel more like stiff mediums, or at least all the used ones do that come from a few people I know.
Do you have all washers still on, or only the Bones washer, or what setup do you have on your trucks in terms of washers?
