I have a 2004 pro-xr with the beefed up race rails. It currently has a 121 to 144 Tracks USA extension and a Camoplast Track. I am changing it out to a 156 so the complete set-up is for sale.
The track has a few repaired lugs (proffessionally done) so is near perfect except for a cosmetic cut where I had a suspension bolt come loose. The track has 2 years since the cut and it has not grown so it is purely cosmetic. The track is notched to fit a pro-x but this set up will work with any Edge suspension. The extension is tipped up so it rides like a 136, not a 144. The hifax has less than 200 miles on it.
I also have the tracks USA tunnel extension required as well.
Everything you need to convert a 121 EDGE chasis sled to 144. $400 plus actual shipping cost.
