ESP is an authorized vendor of Fox vintage decals that are no longer in production.  The Fox Head and Fox Tail are registered trade marks of Fox Head Inc and Fox Racing Inc.  Use, copy, sale, reproduction or publication in any form whether by decals, manuals, apparel or any other products without written permission of Fox Head Inc and Fox Racing Inc is forbidden by law and may lead to legal action.

Factory Forx Setup:  standard oil, level, pressure is 5wt at 6" @ 12 psi.
***Seals are installed with a gap below them, press in 1/4" below top of legs. The reason for the gap is to allow you to use a punch to drive down one side of the seal when replacing, this will cock the seal allowing for easier removal.

Tubes and legs are all the same length, overall length and travel is adjusted by varying the length of the damper rods.

How long will your seals last?
The rubber coated canned seals used in the Fox Factory Forx has a 15 year shelf life, once installed it is less, however there is major flaw in the use of canned seals, if they last 6 months to a year, they're doing good, that was the expectation back in the day.  The canned seals are not designed for high pressure applications over 5 psi, and thus the reason Steve Simons changed to the hydraulic wiper/seal combination in his Air Forks.  My recommendation is to convert the forks to a conventional setup like the OEM's, replace the springs with a heavier standard rate for your weight and riding.  Install RaceTech Emulators for damping.  Use no air, use spacers to set sag if needed.
Condition of the tubes and slider bearings is critical to seal life.  Wear in either will cause flex that you won't feel, but it works against the seals.  Track conditions such as fine gritty sand and extreme mud will also effect seal life.

Bottom line, if they don't leak after the first ride, the seals and installation is good, if they last less then 6 months, it is a possible indication of a wear issue that is effecting the seals.   One year is the norm, if your not happy with that, get away from using air and go with a spring change and emulators.
