Mike do you have to use the optional rear hubs with those arms?

No. I currently have the stock hubs on the arms, I did use the RB5/ZX5 rear hingepin, you do not have too though, you could drill out the captured end on the one side of the arm and use the Rb6 pins.

They don't bleed through a cap, as you don't fill the shocks on the cap side, you fill them from the bottom. The bottoms auto-bleed... there is no nicer shock to build in the industry.

I agree there is no nicer smoother shock, but they would be even nicer if they had a bleeder cap. I guess I will make my own.

If you are bleeding the shocks from the top, you are not building them correctly.

Im bleeding them correctly now, from the bottom. But i think a bleeder cap would make it easier. I will let you guys know how it works.
