New Air Suspension Footers for VPI TNT

James. thanks for the info, I would go back to Bob at elusive disc and ask for a part refund. He clearly has not bothered to treat you as a good customer and ask VPI to supply the upgrade for the HRX only. That is bollocks stating that was/is the only kit available to order.

It is a bit of a pain now ringing VPI as Mike has almost retired so is never in the office, whoever(female) answers the phone just asks you to send an email. a bit frustrating, especially from Australia.

Anyway, you and gladstone say the balls work better than the leaking valves, so that is the main thing I guess.
How long are the balls supposed to last for - Mike mentioned last year about 12 mnths??

The truth is that the whole suspension could still be reworked. I don't think the bulky, black plastic feet are ideal. In any case: all you need are the balls and the cup that holds them.

I don't know how long the balls are supposed to last. Estimates as to their longevity may be based on their use as paddleballs, which may be a harder use with a shorter life than in a table suspension. The good news is that they are off-the-shelf paddleballs that are commonly available and shouldn't cost a lot.

I would emphasize that a complete HRX kit should include at least both the upper and lower cup-shaped inserts and the footer foot with screwjacks for plinth leveling, as well as the paddle balls. (You all know the old footers have no screwjacks. If one subscribes to the view that leveling is not necessary, then using the old footers would be OK.} Black plugs for the tower top holes, as Gladstone mentioned, would be a better solution than re-installing the valve assemblies and metal caps, as I did.

Yes, it's critical to be able to level it properly. In fact the screwjack makes it possible, I think, to align about as precisely as theoretically possible, in contrast to the air bladders, which were inherently more imprecise.

James or Cincy_bob,

Can you tell us if the Reactor balls are the blue ones or the green ones?

Also, did the directions that accompanied them indicate if they should be replaced after a period of time? If they are the blue ones and came in a pressurized cannister (I think), then they may lose their pressure over time in the normal atmosphere.

Thanks for any info you can provide.
