I believe this guy actually engineered a similar air spring as the Fox38 to be used in other forks, maybe try this one out before you try to modify a fox spring to fit a zeb fork. https://www.instagram.com/rgtec_bike_components Luft Fusion air spring for Fox and Rockshox forks | eBay

God no, 38 the most linear air spring on a fork I've come across. Especially with no tokens and adequate pressure. A freshly serviced 38 is eerily close to coil, I've converted every fox fork I've had to a smashpot except the 38.

0 tokens and 5-10% more pressure than recommended is a good combo I find. My 38 is the first iteration with the Grip2, so less hydraulic support. The usual mid stroke hammock of airspring is not perceivable with this setup, there is enough ramp up from the airspring itself to avoid bottom outs with my 180mm airspring. It doesn't have that stictionless feeling for the first 5-10mm of travel like a coil, but as I said, freshly serviced it's pretty close. Worth a try, if you don't like it go back to your previous setup. Cost nothing.

I do find that the 38 air spring is pretty happy in a ton of configurations, all of them rideable. No tokens with higher pressures work super well, but so does more sag and adding in tokens. I've run anywhere between 118 PSI to 96 PSI and fond that I can make something work well in all those configurations. It's actually kind of annoying since I waffle with my air spring more than I ought to. Though I do have to admin that 5-10% more pressure sounds like a lot. I usually run mine (in 170mm) with a touch less...

That is a brutal crash.
