TOPIC:

Hi, I’m working on a GPZ Turbo project and the components in my anti dive unit are kinda shot. I think I could get by reusing the seals and rubber cap, but my springs are pretty worn and can’t be stretched out much. 

I reached out to a spring company and they don’t stock anything like the sample I sent them, but to do a custom order of about 20 sets (minimum order) of springs would be about $400. That’s a bit too much for what I’m willing to bite at the moment.

It looks like GPZ Zone used to make a kit, but they closed up. Any ideas for how I can restore these units?

Bypass the internals.  They don't work for crap and are not worth the effort to restore.

Most would just delete them. Like the air forks they didn't work so well. You might think about some new springs and a set of these.

Check with youngblood on the turbo site> he made some block offs a while ago. Maybe he still has some. They were set up so you could still put the anti-dives back on so the bike still looked stock. If you do go the block off route, make sure they are channeled so the fluid can still move or your forks wont work correctly.

maybe try emailing them and see if maybe they still have a set in stock.
