I've got a set of Fox 2.0 Air bumps, that poly performance set up for 3.0" of travel.

Anyone know a place that sells the DOM inserts for the inside of them to limit them to 2.0" travel.

I haven't pulled them apart yet so i don't know the exact OD/ID of the 1.0 long dom spacers that are currently inside them to limit the travel from 4" to 3".

I really would like to try to avoid going back to poly performance for anything, and would prefer a vendor more local.

Thanks
 
You can send them to me for 20 bucks and some shipping, ill take them apart, add the spacer and recharge them. I have some chromoly that works very well for that and I can have them shipped back to you the same day. If you just want the tube I can do that too.

1.5 .120 wall.

3.4" spacer total to make them 2" travel. (yours actually have a 2.4" spacer in them right now)

Here are the instructions on how to do it:

1. Clean shock.
2. Set shock with Schrader valve up. De-pressurize shock completely.
3. Remove bearing cap. You may need to use a flat blade screwdriver or a small punch.
4. Press down bearing assembly to expose snap ring. Remove snap ring.
5. Remove shaft/ bearing assembly, by rocking back and forth and pulling out at the same
time.
6. Dump used oil.
7. Clamp shaft eyelet assembly in a vise, or soft jaws. Remove valving, negative spring
bearing assembly, and bearing cap. Make sure to keep all valve plates and piston in the
same order as removed.
8. With a scribe remove all seals from bearing. Clean all parts.
9. Inspect all valve plates, damping piston, and negative spring, look for cracks or any
signs of fatigue.
10. Check shaft to see that it is not bent or has any deep pits ( rock dings), replace if
needed.
11. Install new seals on all parts. Use a small amount of assembly lube on bearing
assembly.
12. Install bearing cap and bearing assemblies back onto shaft. Be careful not to tear any
seals.
13. Install negative spring, valving assembly and lock-nut. Torque nut to 30 ft./lb.
14. Clean body assembly, place it in a vise open end up.
15. Fill shock with correct amount of oil ( FOX 5wt.). See below for correct
level. It is very important that you put the correct amount of oil back into the shock!
16. Install flex DU on valve piston. Insert the shaft and bearing assembly into the shock
body. Depress the bearing assembly to access the snap ring groove.
17. Install the snap ring. Check to be sure it is completely in its groove, this is very
important!
18. Install bearing cap.
19. Remove the shock from the vise. Place shock with Schrader valve up.
20. Pressurize the shock with preferred PSI.
21. Compress the shock to make sure it is working properly.

And the oil values for rebuild:

2.0 - 4.0 BUMP STOP (1.25) 125CC

However.... for $20 though you cant really go wrong....send them to Alex.
 
You got it. The 1.5 .120 fits a little tight and I dont like the higher chance of scratching the shaft. I use some 1.5 .095 4130 I have laying around.
