Air Shock Tech

I broke my winch cable, using as a suck down ( strap before that). I am thinking thick chain will be the next attempt. That being said, the truggy beat me to death without the front sucked down a few inches. It also went back to unloading and feeling unstable as ****.

pulled my rear shocks out again and replased oil with new and re filled them with 200cc, raised the ride height front and rear to halfway and went to test drive

front feels fine now but rear still feels very stiff i think i have to change valving to get them acting softer in faster speeds

Have you tried different weight oil in the rear?

no been messing with 5w syntetic oil in both ends. maybe 2.5w oil would help too

It works similar to changing valving just don't have to take the shock apart only problem is it changes your compression and rebound

I don't generally recommend tuning with oil viscosity or using something other than the manufacturer recommended oil. The seals, piston rod and oil all need to work together and changing one of those things can impact durability.

Does the rear feel stiff because you're still hitting the air bumps or is it just valving?

Try to break the stiffness down into separate things:
Hitting a rock (compression damping)
Small washboard (bleed)
Series of bumps (most likely high speed rebound, but could be compression)

Good point! That's a good way to think about it, I have a light Toyota with 16" 2.0 fix air shoxs in the rear, they came valves from the factory with 40/90. So my question is cause it being so light in the rear, the (90) is rebound, I think I need to lower it down to 60. Re valve is what I'm talking of. Like when you say a series of bumps.

The oem Fox valving is very far off, you're going to want A LOT more compression and less rebound. I haven't tuned a Fox air shock in a long time but 90/50 is closer to what you'll want. Fox and sway-a-way shocks are a lot different so this isn't a good recommendation for the original poster on what changes to make.

Ok. My 16" Fox 2.0 are running 380cc of fork oil I think 5wt. And 165psi of nitro. I have about 6" shaft showing at ride height.

did some revalving to my shocks and refilled them front has 250cc oil and rear has 220cc oil now
running 7" shaft

valving stack was

some test driving to get some baseline for them

Lol rides rough as shite. Us air shock guys weren't meant to run whoop sections.

I love the tech though. Without it we all struggle more when we are new at it. Cool vid and thank you

How many times do we have to tell you air shock fawkers to keep your tech in the correct sub-forum?

filled 270cc oil
now has nice soft feeling when wheeling forest trails, i still need to do some faster speed driving to if i have to make valve changes to upper part of the stack. pulling the bleed screws out made huge difference to softness
