I was helping my cousin dump some things he didn’t need this past weekend and happen to find this in a random box. I snagged it and decided to clean it. Seals were shot and it was dirty on the inside. It turned out pretty clean compared to when I found it, internals are still nice. Should I get a rebuild kit? I kinda want to just because but I know I’ll never use it. I know it’s an older model but what’s the valve of this in its current state?

Well, I'm not finding the thread in search. So I looked at reddit to see if maybe I had read it there, and not finding anything, so unsure where I'm remembering that from.
I had a max flow on a PVI Shocker, and they were rock solid, but that was more than 25 years ago, with different equipment....

They're fantastic regs, just bulky. All orings inside, including the reg seat, so almost no proprietary parts. I run one on my Matrix.

The piston is much smaller on the HP versions as well... unscrew the cap off to see it. I'll post a comparison picture of my HP and LP versions tonight if I have a chance.
