Or a cheaper route would be to weld in a some right angle steel onto the OEM links. That should beef them up enough for rocks. Not adjustable but would only cost about $20 in supplies and an hr on the welder.
I'm planning to weld up mine (if I can straighten them) this winter. Let me know if any other CO VXers want to go this direction, I could lend a hand or some welding...
...and you're not alone Tom. My driver side link is severely bent but it doesn't seem to throw off my steering much.
Even better would be to cut one end off and sleeve them and weld the end back on.
