Fox shock air sleeve service

Shelley's Merida originally came with a remote lockout for the forks and shock. That set the climb, trail or descend (CTD) mode. The remote was troublesome and I removed that not long after she got the bike. This left the rear shock permanently in the descend setting.

I've been looking for a way to convert that to have the shock mounted levers for control. I eventually found out, from the exploded diagrams, that there is not a conversion, it needs a complete replacement top. To that end I've been on the lookout for a compatible shock at a low enough price to be a donor. I bought a 200x50mm Fox FLOAT shock of the same generation, off of eBay, that will do the job.

I've carried out an air sleeve service but swapped parts between the two shocks as I went. There is an easy to follow official service video on the Ridefox site for the service.

I removed the mounting hardware.

The service was as easy as it looks in the video.

The original shock is a 190x50mm but by swapping the air sleeve, I've ended up with a 192x50mm, which I think is close enough. It'll add about 5mm to the height at the rear. That will easily be lost when the sag is adjusted.
