Hi,
Ive got myself some lowers from a 2009 140 floar r(coil)15mm dropouts which i want to swap with my 2009 qr 140 float rl(air) lowers, is this possible?

You can but as far as I know you will have to run them as coil as they won’t seal properly as they’ve been used with coil already. As when I was checking about converting my Talas to float I enquired about going coil and was told if a convert to coil I could never go back to air because of this. Hope that makes sense

I know that you can change lowers however not sure the coil/air would make any difference or not. You could try emailing Loco Tuning or Mojo Tuning and they’d be able to set you right.

HTH

Cheers, I will send them an email and see if they can give me any info.

Yes, they’re fine same travel and model year, bushes may need adjusting to get really good performance due to possible wear/tolerance differences between the uppers/bushes. 😀
