Hi Greg,

Yes you are correct, the spring seat between the main spring and the tracking spring slides on the shock body. I had to make this piece to locate both springs corectly. The shock can still use it's full travel 5" and the rubber bump stop works fine. During normal operation the tracking spring is fully compressed so the sliding spring seat doesn't move. The tracking spring can't twist out of alignment because of the lip on the bottom of the sliding spring seat.

I wouldn't worry to much about needing this set up. When you get your shocks in at the right ride height with the correct weight on them they will probably be fine. I think one of the reasons my chassis is designed this way is to open up the options for spring rates. I've seen similar set ups with 2 different rate springs on the shock to give a rising spring rate for a more progressive ride.

Cheers
