It does seem to work well!

Sometime in the last six months Matco's axle was up for discussion on the list. My hangar mate and I purchased the axle and Desser's new two rib tire and did the swap. Does it work better? I don't know but I do like the fact that I can set the bearing load before installing the axle/wheel assembly in the fork.
 
Just finished the axle upgrade on the RV-8A

I just completed the nose gear mod (gear leg, fork, fairing brackets) with all new parts. I went ahead and added the Matco axle based on forum comments. I like the setup much better than the "pucks" ---- still have the RV "wiggle" on the nose gear, so no improvement in that area.
