Honestly, I find it so odd that Independent (and other brands too) color code their bushings for different durometers and then throw that out the window when it comes to the stock bushings. They don't really state anywhere that all bushings are 90A regardless of color unless you ask (like the photos a Pal posted above) or dig for it like we're doing here.
Thanks everyone for confirming and it seems I'm wrong about the stock ones, but right about the aftermarket ones.
I'm still tripping out because the stock red bushings I have previously used feel way different than the orange ones. Same thing with those AVE white ones. Maybe those were rare one-offs for me.
As I had said before, between lots of different trucks, I have felt like the stock bushings did feel different, some a little stiffer and some a little less stiff, even verging on stupidly soft at first, but after a few sessions or more, they all seemed to firm up a bit even though some still come out a touch more this or a touch more that.
So as far as the info they give you, I agree with you in that not all stock bushings feel the same, even if they are all supposed to be the same 90 duro on paper, but they are all a different compound to the aftter market bushings and perform differently, even in what is said to be the 90 duro bushings, for comparison.
The stock bushings do seem to split, come apart or have other issues, whereas the after market bushings don't seem to have anywhere near as many issues as the stock ones, for whatever reason. I have still seen all of them end up squashed or split or whatever from being tightened down too much, or specific things that will cause them to blow out more often, but I think overall now, the Indy bushings really do hold up a lot better so regardless of anything else, I am happy to use them, as well as happy to recommend them to anyone, from super soft right through to super hard and anything in between.
