Contact Neil at
ATV Racing and ask him about the shocks that Crash is now making. (no I'm not joking - ask about Crash's shocks.)
Crash, as he's called at ATV is Mike Hallock - the guy who originally designed and made Custom Axis. Really great shocks until Penske took them over. Once that happened, they quickly became a less than stellar unit.
As always, it's very hard to beat Fox for a shock - any shock. Coil over, air, air over coil, bypass. They make good stuff and are very reasonably priced. Doug Heim sells them here on the site.
