Is this a problem unique to the excel g
I fitted agx's on mine and it didn't come with washers and tightened ok
Not all require them. If the spacers / washers dont come in the kit, more than likely dont require them. Its only for the inserts that are slightly shorter in length. The units (shocker inserts) probably suits a variety of Toyota's eg, camry etc. I know Monroe GT inserts are in this boat.
From my experience, If the inserts come with spacers / washers, I would be inclined to installing one if not both.
Then when doing up the flange nut, if it torques down with some thread on the tube still remaining - then it will be fine. If the flange nut tightens down all the way down the treaded tube, then I would ensure spacers are installed.
