    Boxxer seal leak

    Well it was bound to happen after 2 seasons of use. My 2011 Boxxer r2c2 fork has a leaky seal on the left side. I bought it new and it has been an incredible fork until it started to slowly leak on my last 2 runs at Highland Mountain bike Park yesterday. The boxxer seals have been great as evidenced by 2 years of maint. free bliss. My question is after reading up on this should I go with the OEM Rockshox seals or the Enduro seals? Slick Honey seems to be the recommended grease to use on assy. I am a very technical person (i am a copier technician by trade) so I may try to do the job myself. How hard is it to do? Any recommendations are appreciated!
    I'm thinking about shreddin' it up right now!

    easy and the enduro seals stick. you should also service your fork more then once every 2 season

    So use the OEM Rockshox seals? I know I should service it more often so I'm told LOL.

    yes the oem ones work best i have found. the enduro seals were good but i felt they were sticky and never really broke in. your lucky your fork lasted that long. by the end of the season for me my seals are shot. but it is really dusty where i am

    Any tips on replacing them. I've watched some YouTube vids and have the service manual as well. 10ML of oil 15w oil? Do you have any preference on oil type and quantity?

    use the recomeneded tq specs on everything. clean everything really well.. dont use to much greese. i use AMS oil in my forks. works well and its good stuff but if you can get any then just see what your local shop has

    Why were Enduro seals ever popular? Ever seen them on a Fox fork....you'll need new uppers within a month or so. I put Enduro seals and Chris King headsets in the same category.

    OE seals, remove the sticky grease RS packs them with, apply a thin film of Slick Honey, 15-25ML of ~15wt lubricating oil in the lowers.

    I ran Enduro seals on my Boxxer for a solid year with no leaks, sticking, or rubbing. I went thru 3 sets of OEM seals in 6 months and then switched to Enduro. Maybe I got lucky, but they were way better than OEM

    they last longer for sure and you wont have leaks with them but they do stick way more cuz they are so heavy duty. if you lube them up with for fork oil before you ride they are fine but if you forget you can feel the fork slow down

    Since only the left side is leaking would it be ok to replace the seal on just the left side? Stupid idea??

    to quote you " its a stupid idea". your going to have the fork taken appart you cant just buy one seal. do it right or leave it be. also thats a good way to mess the fork up by only maintaining one side

    So both left and right sides take 10ml of 15wt oil from what I'm reading in the service manual. Conflicting reports in this post have me leaning towards still getting the RS seal kit.

    After 2 years you need more then seals bushings perhaps.

    yes and yes. the enduro seals are not horrible and they last alot longer but you need to put fork oil on the stantions before you ride to help it from not being sticky. th oem seals are fine i would just suggest at the end of each summer servicing the fork and also if you go on a muddy or dusty ride clean the dust wipes off really well. it helps dirt not get in the seals and oil

    I have always kept the dust seals super clean. Prob why they lasted 2 years LOL. From here on out I will do them at the end of every summer. I'm going to buy the seal install tool as well.

    yes 10 mil in each leg..
    Its all a piece of cake, really.. go to home depot and get some PVC pipe attachments to use as a seal press and dust wiper press instead of buying the expensive tool.

    I find that if you change your oil and regrease with slick honey regularly, your seals will last a very long time. Also, you get used to how nice it feels after the servicing.

    In the summer I try to do it monthly, overkill maybe, but it takes 20 minutes or so, grab a brew, work on the bike, good use of down time for me..

    What size PVC piping should I get instead of the install tool? Any recommendations as to what to get for oil, where to get it and where to get the slick honey? I have a local bike shop but not sure if they have that stuff and dont want to pay through the nose for it either LOL.

    I can't remember the exact size, I took my boxxer lower to Home Depot and sized it up..

    any 15w oil is fine.. slick honey is pricey but lasts forever.. I got mine online at Pricepoint I think

    The Boxxer is what I have so its what I have to work with. I dont mind doing the maint. It was actually pretty simple. I bought it new 2.5 years ago and it lasted almost 120 hours of riding before the seal let go. I'd say I pushed it LOL. Still looks in great condition though.

    I use Enduro seals on all my fork rebuilds. The key is buying them from Real World Racing (Chris is an awesome person to deal with). They machine the regular Enduro seals and remove redundant wipers to lessen the stiction.

    OEM seals on my Boxxers lasted half a season (leaked the entire time too). The Enduro replacement has been there one year and not even an oil ring, and it's buttery smooth. My Zoke 55s were the same story (one year old OEM seals installed by the factory and leaked immediately). Just replaced them last week and the fork feels like a Pike (well, I'm exaggerating. But the fork felt so good I was taking choppy stuff with AM bike like I was on my DH bike).
