I bought oem LTR450 tubes and ends to use with my Fireball arms. They are 12mm and the proper taper and length to use stock banshee stem and spindles. Elka is notorious for sending shocks out that are poorly setup new which is why I say to order them through a builder. Fox and Axis do a much better job out of the box in my opinion.
Look good. If those are 12mm tubes I'd recommend oem yfzr tie rod ends. If they are 10mm tubes I'd recommend getting 12mm😁. Get Fox or Axis shocks. If you go with Elka order them through a builder and not through Elka or a website.
