I got a sweet deal on a 2012 forty-eight but after riding it an hour on 580 from SF to Dublin I decided something had to be done about the suspension..

I just installed a set of progressive 412 cruise shocks and ran into two concerns I thought somebody may have some insight into:

1.) One of the shocks is about 1/8(maybe 1/16, didn't actually measure) longer than the other. OR, the swing arm is out of alignment by that much. Is this normal? I unfortunately put the shorter side on first and had to remove it and do the longer side first. Then, I had to fiddle with the lift to lower the bike just right so as to compress the other shock and line up the bolts just right on the other side :|

2.) One of the shocks makes a hissing(swishing, sucking, etc) noise when I bounce on the suspension. Just one. Sounds like a mint FOX mountain bike shock. This wouldn't concern me that much except that only one of them makes the noise. Is this cause for concern? Any else experience this? I may have to email progressive about this...

Any advice is welcome! Cheers!

 

Are the.preload adjusters set the same?

 

Yep, both set two clicks up.

 

The noise is mostly gone this morning. I suspect that it needed to circulate some oil around.
