The last set of Tracker Axis trucks I bought were USA. Too bad I cracked the cast baseplate just doing flatland stuff. Tracker doesn't seem interested in forging baseplates, so I'm not buying from them anymore.
I emailed Venture last week and the guy said their stuff is now made in Mexico, which to me is still better than China for various reasons, but not ideal.
I still have a pair of Indy stage 8s (purchased new in '98) on one board that have held up after all these years. I'm watching Ebay for more of those.
