Last week I upgraded the factory Fox shock reservoir caps to some JC Racing caps with recessed Schrader valves. I bought the nitrogen recharging tools from Schmidty Racing Suspensions so I could refill the shocks with nitrogen and got a 20 cubic foot bottle of nitrogen from a local welding supply shop.
The one thing I had to make a parts store run for was a Schrader valve extension. The SRS tool has a no-loss chuck, but required the use of a Schrader valve extension since the JC Racing caps are recessed. I bought a 4-pack of Slime brand extensions, but they do sell a nice brass extension on their site. I'll include links to everything below:
JC Racing Fox Shock Reservoir End Caps with Recessed Schrader Valves (Talon R = 2.5" caps all around)
Schmidty Racing Suspensions Nitrogen Fill Tool
Schmidty Racing Suspensions Schrader Valve Extension (must have with recessed Schrader valves to be able to thread the no-loss chuck on)
Valve Stem Tool (I already had this tool, but it was used to thread onto the recessed valve and pull the cap back out to reseat it after installing the cap and installing the retaining clip)
The install is very simple and straight forward. I didn't bother measuring the PSI in each shock with a needle, but as I listened to the nitrogen release from each shock after drilling the holes it didn't sound like much was in them. Again, I can't quantify the PSI measurements for the stock setup, but 200 PSI is what they have now and I've got the ability to maintain them going forward.
I've got a video I'll be editing soon and I'll edit this post to include it here.
