Fox 803-00-977 Reservoir End Cap Upgrade For Stepped 2-1/2" Aluminum Res Includes Schrader / O-Rings

These caps allow you to convert the needle pellet style reservoir end cap with a more common Schrader valve. They fit the 2.31" inside diameter internal STEPPED reservoir only. On the stepped reservoirs, the main chamber is 2.25" but down towards the end of the reservoir sleeve, the inside is stepped to 2.31" inside diameter.

Note: In order for you to screw on your typical pressure gauge no loss chuck, you'll have to purchase a Schrader valve extension separately. We do not sell them. Slime sells a 4 pack, part number 2045-A that you can pick up for a few dollars at almost any regular auto parts store.
