Fox Shock Tuning

any updates in regards to the rear set up?
how much do you weight?

I made some updates this week. Plan to run it Sunday. I will report how it worked and what my settings were.

I am about 155lbs.

Got a chance to run it hard today after my latest changes. Here is what I am running.

Front (same as before):
Compression: 70
Rebound: 30
Oil Volume: 300 ccs
Nitrogen pressure: 175 psi

Rear:
Compression: 70
Rebound: 85
Oil Volume: 330 ccs
Nitrogen Pressure: 210 psi

The rear was definately better than before. I still have some bucking, but it isn't as bad as before. Unfortunately (I guess) the rear is back to a stock setup with the exception of a more fluid volume. I REALLY like the front. I am not using the last 2 inches of compression of the shock due to the amount of fluid I am running. But I like it because it gives me a good bump stop at the bottom and I am not digging the front end like I used to.

I am going to run this setup in my next race. So I will report how it works.

Your the expert Fox tuner now.

Doctor Shock? ............. sorry couldn't help it.





Thanks agin for all the info.

Don't know about that...........I'm just reporting what I am doing and how it is working for me.

Well thanks again for letting us in on your hard work. Valuable info!

Unless someone has pulled apart a shock before, they'll have no idea how messy the job can be.

I never did hear back from Fox. I'll ask agin.

It's not as hard as I thought it would be. I've taken them apart about 4 times now. I can now revalve all 4 in about an hour! Unfortunately it takes about 2 quarts of race shock oil per 4 shocks. And at $20 a bottle........it gets expensive.

$20 a bottle ......... ouch.

Yeah. I'm using a real highend, synthetic version to try to keep them from fading with heat while I'm racing. So far it has worked well. But I do notice them fading after a while of hard racing.

Another advantage of coil overs...........no fade.

Thought I would post an update on my, seemingly endless, shock tuning experiences.

Finished second in my latest Whiplash race in Snowflake, AZ. The course was mostly wide open throttle desert racing. But this course has some nasty 2 foot tall berms that cut straight across the course in the highest speed sections! And with a rig that likes to buck, and buck bad, you gotta keep you eyes peeled.

My latest settings are (not sure it has changed from my last update):
Front:
Compression: 70
Rebound: 30
Oil Volume: 300 ccs
Nitrogen pressure: 175 psi

Rear:
Compression: 70
Rebound: 85
Oil Volume: 330 ccs
Nitrogen Pressure: 210 psi

The front end is definately where it needs to be. I don't bottom the front end and it dances well over whoops. The rear still bucks, although not as bad. Since I have lightened up the compression (to 70), I notice that the backend wants to bottom easier than before (with higher valving). I smacked the rear, bottom skid several times throughout the race. Didn't hurt the rig, just jarred my kidneys. I find if I put more valving in, then it doesn't react as quickly and the backend feels "slippery" in the whoops and bumps. Too light, and it bottoms out. If I go higher on nitrogen charge pressure, it bucks worse. So..............I think I am about where I am going to be with this rig and Fox airshocks.

One thing to report is that at the end of my last race, I had a front shock blowout on me. As I pulled into the pits (after taking the checkered flag), it basically pissed all over the ground and went flat! The race was REALLY muddy. And out here, the muddy water is really abrassive with granite and such in the mix. So it just tore up my seals. New seal kits on the way.

Other than that, I think I have it about as good as it will get with this setup. Nice and plush riding, handles the whoops REALLY well with good control, and doesn't buck as bad as it did out of the box. But can still get the ass over the front if I'm not careful.
