Rockshox Revelation 426 U turn Air – which service kit

How can I find out which service kit I need for my forks?
And any recommendations as to best source?

Not sure what year they are either – 2010?

Thanks!

Have a look on tf tuning website, there’s a lowers kit and top seal kit. Normally you’d just do a lowers service, but if it’s been a while, you need both.

just done this on miine, used the tftuned one after some problems with a cheaper one on evulbay i got for 8quid.
tftuned has different packs for different year air u turn revs, the service itself is dead easy.

Thanks!
