So couple things on the TKE telescopic jacks.
The runby and bottom overtravel are critical for it to work correctly. Minimum bottom overtravel is 8-1/2” and ya, the jacks need to be at the same height. If you pull the springs and manual lower it, you must be clear of the buffer stands so that you can bottom out the jacks to get a full manual re-sync when necessary. It’s a super common misconception that the bolts are long so that the jacks can fall away and bottom out when the car does an auto re-sync. The inertia bolts, or jump bolts, are for hitting the stop ring at high speed. If the measurements are correct the check valves open when the car hits the springs. It should be set to do it once a day and I max out the duration, I think it’s 30 seconds. Make sure the inertia bolts turn by hand so you know the jacks aren’t bound. Always pull the springs and do a manual re-sync when you’re having any trouble. You can sit a piece of paper or cardboard on the stand when you do it so you can see if it’s bottoming out or not.
