Hey so I've checked out as many threads as I could, and I still couldn't find my answer. What RCS Ti Spring do I need for my 9.5x3.0 Fox RC4? Using BTI as a reference...It would appear that I need the DHX/Elka spring, but a buddy of mine got one for his 9.5x3.0 RC4 and it rubs real bad on this shock body. Can I run the Manitou, Marzocchi, Cane Creek or Progressive like the RT-3050 spring on my RC4 since the inner di is 1.43 rather than 1.38? Or will I still get flex and major rubbing? Is Obtainium the only way to go? Thanks!
