Revalving oem shocks for Geiser springs

There is no need to revalve the shocks

I think the key word here is "need".....The rebound damping is too light at full bump for my taste...front end has a tendency to pogo...
And my gut feeling is that adding spring rate in the form of a set of Geisers would make the issue worse...
It's not as if the factory suspension valving sucks, it's just I (and others) feel it and would love to give the front shocks a tweak to get it closer to perfect for my trucks usage...

So if you don't use all that travel at various speeds then yes, the valving is just fine...

I think you'll find the pogo issue gets better with the Gieser springs. it almost completely goes away on small bumps. The progressive wind gives them a soft spot in the first part of the compression travel. With Gen 1 trucks, i decided to run them at mid perch since the low perch setting made them a little too soft for my liking. It felt a lot like a dirt bike, which was ok, but it also gave the truck a lot more brake dive under hard braking. Mid perch leveled out the truck completely and still gives me some of the softer ride I had on low perch, just not as "mushy". I wish SVC made a coil adjustment collars for gen 1 so you could dial it in a little better. Cant help but feel that somewhere between low and mid perch would give an even better ride

That said, I would like a little more rebound damping too for high speed dirt roads, especially whooped out roads. Still watching where this goes.

In your posts you said you want “max” rebound damping at full bump, and that the stock rebound is too “light” ? I don’t know what you mean by “light” but I assume you mean you want to slow down the rebound speed, since rebound adjustment speeds up or slows down the rebound stroke.

You can’t adjust where the rebound damping/speed functions in the travel without high and low speed rebound adjustment circuits, it cant even be done with just a revalve.

Im sure you can get a revalve done to slow down the overall rebound , but the “pogo” issue has just as much to do with the rear settings, probably even more, than just the front rebound speed.

You can spend 7k on your suspension with a Fox 3.0 setup and you still won’t have rebound adjustment with the front coil overs, and only single speed rebound on the rear.

You may also want to do some research on progressive vs linear rate springs. Geisers are designed to lift the truck and feel like stock. I went with linear rate Eibachs, which in my opinion will work better for the off-roading that we do.

And that's what I would hope for....I really need to be in a Gen 2 w/Geisers installed to see how they feel for myself...The other factor for me to run those springs is the new ride height would give about 2 more inches of compression travel, which it could use when doing desert type runs at speed...

Really?...never heard it needs more compression?...loosen up the rebound it's packing up in the whoops?
There are several terms used to describe what you want the shock to do...Read some dirt bike reviews..."We found the compression to be too light in the front end" and yes you now know the valving is soft and it bottoms out to often/easy...

What?....these are by-pass shocks!....they have several "zones" where fluid by-passes the piston and of course zones where they don't....OK...now I get it...you're pulling my leg!
You got me..

I’ve raced off road bikes since I was 16 and I’m old now lol ... you weren’t talking about changing your compression, which yes is a hard and soft ... or “light” adjustment ... rebound is simply a speed adjustment.

On a bike you don’t just change fork springs or cartridges and revalve the fork stack for your weight and racing type without doing the shock as well to balance the suspension. Which was my point about your pogo issue, your rear suspension IS just as much an issue with your pogo issues as the front.

Just trying to help, but you seem to have it all dialed boss ... Good luck.

We run a full King external bypass setup on another desert truck and I’m well aware of their capability is as well. But good luck trying to slow your rebound all the way down, but only when it’s coming off full compression.

Yes, any veh should have a balanced suspension frt & back...and I do realize that what I'd like to see accomplished up front won't be what I Wish it could be...but would like to see it head that direction...
The rear can affect the frt, BUT I've bounced the front end while the rear behaved...
The last time out we hit a smooth jump at 80+ and the trucked landed, bottomed out frt & rear and then bounced up again just a few inches, then came back down smooth...in this case the front & rear acted very balanced...
