I do still use QA1 rod ends and hardware on some arms, however, for my rear multi-link (including this RUCA) i now go direct to source for non-QA1 Endura series equivalents.
I just had and still have some Peak, PBM, and Tanabe arms around of late… all of them had noticeable play or other significant issue with the rod ends. They are not cut out for Canadian use. The rod ends i use are far more appropriate. Only SPL uses an equivalent spec. Everything else is lower quality.
