Just wondering if anybody is using another manufacturers shock shafts? Amain and Tower are out of stock of the front shafts. I haven't bent one yet cause I am just rebuilding the used one I bought but I read front shafts can be troublesome and wanted to get a couple just as back ups. What are other spares I would want to have on hand? I also saw the spur may strip easily? Is the exotek spur and alum mount plate a good fix for that issue?
