Esr elim kit. And alli do is dune, so an outerwear on that is more than fine. But if keeping an airbox, I am useless for info. Never tried it.
It is a Koq or kids on quads. They were 499 new when I bought it. Cheaper than a used Roll and the gull wing is supposed to help the air box clearance. Why run it? One, I already bought it and two, I'd like my rear suspension to work better. Especially in the whoops. I'm not sure what I'm going to do on the air box yet. May just go with an eliminator. I think with the stock frame it is not as bad because the air boot fits next to the shock body vs with a long shock it will be against the spring. I was gonna build this for desert but I think now it's just gonna be a duner so the AB eliminator may be the easiest.
I have no problems with my intake on a no link roll swinger with stock chassis. I have heard many people claim all these issues and shock relocation, etc. I Literally changed the shock and swinger and that was it. Obviously if you want to run a longer shock or change trajectory of the shock angle then so be it. But at that point, you already know what you're setting yourself up for and check all your bases, and also have the abilities to figure it out.
Maybe try the brembro brake caliper from race tech titanium
