What do you mean by how far is the slider from the lower spring?
Bad Lines Good Times

Thanks for the reply I appreciate. So here is the numbers.
Shock shaft showing at ride hight 6in
Lower spring length 12
Upper spring length 10
Spring preload lower 11 9/16
Upper preload 9 11/16
Ride hight spring length lower 9 7/8
Ride hight spring length upper 7 3/4
Slider to retainer nut at ride hight 1

Perfect, i like your spring rates and preload, your good there, i would do a progressive stack in those with a flutter, the only question we need answered is what piston you have and how many bleed holes and what size they have in them, i dont like the fox chart for valving its more complicated than they show a bleed changes a force curve so much can you pop one open and see what you have right now?
prerantaco
I won't be able to do that today but I'll try and get to it by next week. A progressive stack how does that end up varying compared to a standard stack? And the flutter is the first on the piston then a spacer then to the rest of the stack correct?
ADSRACINGSHOCKS
a straight stack is say a bunch of .015 one of each size, a progressive will start out with a light shim against the piston for small bump compliance and then work up to heavier shims to provide resistance on a faster harder hit
ADSRACINGSHOCKS
a flutter is a light shim against the piston a spacer and then the full stack it lowers the crack pressure and eats up chop but hits the main stack on hard hits, i did a write up on here in the suspension tab i want to say its called valving theory

Ok I read though it be for but it's one of those things I haven't messed with yet to know how it works in the real world like actually making a change and feeling the difference. I don't have a problem tearing into them and doing the work in the desert. The next trip out I want to dial the front in and want to have the right parts to swap out.
prerantaco
The first time I had the truck out the rear was harsh and needed adjusted. So I did research and found i needed more rear weight so I added a 32 gal cell plus left the stock 15 gal tank for smoging the next trip it was better but
prerantaco
needed to turn tubes that's when it was working well in the rear but front was bottoming out and not keeping up. We've been doing tests on Barstow main and the road next to outlet center Dr near Barstow main if you know that area.
I really appreciate the help

main has some big holes, and watch for the hidden rock haha, weight is a big deal in any truck, imagine riding a motorcycle on the handle bars thats what a stock truck is, everything is in the front, getting weight bias towards the back is a huge improvement, finding a balance of up travel and weight is tricky on leaf springs but not impossible

Ya I had an idea on how it would help but it was impressive my buddy that's newer to prerunners was blown away on how much it changed and once I get how to revalve he's going to need it too on his Toyota. He had a question for me that I'm not sure the answer on and maybe you could give me an answer for it. On a 4 in Long bump stop can you revalve it to act more like a regular shock and put it a reservoir on it?
ADSRACINGSHOCKS
you could but you wouldn't want to rely on it that much that it would be getting that hot. you can re-valve them and or limit the stroke to match the combination, i see it all the time too much bump stop for the application and poor results because of it
prerantaco
So the idea we had was to take my buddy's 4in stroke 2.5 foa bump and use it like a shock/bypass if we could add tubes to it and revalve them. He's got an old fab tech kit that we converted to uni ball, It's pulling 12in of travel or so running coilovers now

So I had the idea like back in the old days when Kaiser shocks was taking threaded body's and converting them to bypass's and adding tubes so we got thinking about doing that to the bumps of it could work
ADSRACINGSHOCKS
you can turn it into a shock but it would be better to turn a smooth body into a bypass and then use the bump as a bump, the bump should be your last component in the suspension to save your butt, totally relying on it will have lack luster performance.
once we know what we have there we can see about valving.
