Thread from the dead, but I am trying to identify which generation of SPC arms I have,.the part number has not changed but the product has since I purchased them, apparently. Today, the same SPC 25460 I purchased 4+ years ago still fits a 3rd gen 4runner, it just looks different and costs two enas much.
I purchased the tubular arms in 2018, and sat on them for a considerable time - I didn't install them till 2022. At that point I had heard about "problems" so I called SPC, the asked me to describe my arms, bushings etc, and said they had already updated the bushings on my arms, so I was GTG.
I installed mine and have had no issues, however I have heard about ball joints failures occurring - not sure when those became an issued, if they always were, or if some folks just got unlucky. Now I'm genuinely curious...
Someone on FB posted this in a conversation, I don't know what here is fact or lore:
FB person had my failures right around the 10k mark. But the real issue is quality control. They've had three major revisions of the arms (three different bushing styles) and changes in the ball joints. The oldest versions had issues with bushings and cracking in the welds. The second revision seemed to be the best (the version I had), but still suffered from bushing issues. And the third revision (the forged models) have had issues with the x axis joints and several runs with bad ball joints.
I'm not worried about my SPC arms, built how can we identify what generation SPC and when the problems plagued each model/changes were made?
