Default What is your Fox 2.0 Valving on stock springs?

I have searched and searched but most end up discussing Sulastic, aftermarket leafs, tire psi, etc. wanting to stick strictly to valving please.

I have an F-350 CCLB Dually(yes) air bags in the rear, stock springs and Fox 2.0 performance with reservoir on all corners. That I use to tow a 16k fifth wheel with. Valve code on the dust cap is T/90, which from what Iíve gathered is something like a (flutter compression)30/90(rebound). The issue I have is the truck will dip in slight hole and the compression is not fast enough on the coming out so it bounces out. Yes Iím aware ďitís a truckĒ but I believe I can make it better with a few changes. So Iím gonna re-valve, which any body that has tried will say itís tough to get it right on the first try.

So of course call Fox and see what they say....... ďthe piston I have is a single bleed .070 and code was last updated in 2009. I should add .070 bleed to all pistons and change the compression side to #50 in the rear(to work in conjunction with the bags and change compression to #70 in the front......i could be wrong(hence why Iím here but)I would think increasing the stack thickness from the .008 to .012 would have the opposite effect of what Iím trying to achieve. Making compression stiffer. Hoping somebody has a similar setup(stock springs/aftermarket bags and 2in shocks) that wouldnít mind taking a peak at their dust cap(where the shaft goes in and giving me some idea of what I should be going for.

Thanks

I've been told more than once you want to allow compression and control the rebound. Make the spring work. I know it's all about personal preferences. Not to mention what PSI are your tires.

Thanks for the reply, Iíve tried dropping tire psi to 30, with the same results.

No one? Well I guess Iíll do some experimenting. I talked to Fox again today and there actually was a misunderstanding of what I was after. Said ďAdding 2nd bleed port would allow a lot of low speed, we want to use compression to control it. So use a #50 stack(0.010) and keep the same flutter pivoting on a 0.008.Ē I have riden in the truck and know how it feels and what I believe it should feel like, canít help but think increasing to a #50 stack would yield a similar performance to what Iíve got now...Being that it takes all of 15 mins to rebuild a shock I figured why not just toy around, see what I can come up with.

Got a few things to do tomorrow so want to leave this here in the hopes someone that knows will tell me ď hey youíre screwing upĒ or ďyea looks legitĒ
Hereís what Iíve got so far.
Move my thinnest 1.42x.006 to front to allow more flex and flow
Move my 1.35x.008 to the second position for support
Leave the .8x.010 for pivot
Move my 1.6 to the 4th position to give the flow leverage in the high speed as well as support for the ďfront lineĒ so to speak.

For 15 mins of work even if it's not right sounds like an easy fix. Go at it Bro. You are blazing the trail.
