Rear suspension really kicks back with fox floats

[machinest660]

I am running the timbersled mountain tamer rear skid in my pro, I am having some trouble to keep the rear from kicking back and wanting to send me over the handlebars on the rougher trails,I have 60psi in the FTS and was running 110lbs and 150lbs in the evol on the rear shock, there is no rebound adj, I am still bottoming out the rear and was playing with the evol pressure but when i had it set to where it didn't bottom out it really seemed to kick back? Do I need to send this shock to get revolved or updated to one with rebound adj in order to get the kick back under control??

What is your order of filling... evol and main pressure?

Do you have 3 1/2 inchs of SAG??

Just to clarify - always set your evol pressure, first. Then main chamber.


I didn't know the Evols were offered without the R (rebound), but it sounds like you know what to look for. I do have Evol Rs (Carl's), and the rebound adjustment works. It's a screw, not a dial, in the RTS. I'm now running about 125 main, and 155 Evol. 9 clicks out from slow on rebound. Depends on what's on the tunnel. FWIW.

I got carls Evols Rs on the front, just had them rebuilt as the evol pressure was leaking into the main chamber, now that there working properly and I took some time to set them they are awesome, Now if I can get the back to work like the front I will be pretty happy.

You could have a shock issue with the rebound valving... is this a new skid, How much riding do you have on it.

I've had that same skid and shocks... but never had those symptoms.

Something is wrong, thats for sure.

Post up some photos of your skid.

A coupled suspension, which this in reality becomes, once the "slider" in the rear scissor touches down/reaches bottom position will behave strangely when it tries to transition between "compressed front shock- extended rear shock" to "extended front shock-compressed rear shock" when going over a sharp bump.
What it does is going from only compressing the front shock/spring to trying to compress both in a 1/1000 of a second. This can feel like it bottoming out or extremely rapid rebound but actually depending on the rear of the suspension almost not compressing at all. Just for a test, try rising the air pressure in the rear, (or both), shocks rising the ride height and giving the suspension more room to move before the "slidey bit" hits the bottom.
