my racing 1025r has a older fox double clicker shock. i got it at a salvage yard. as long as the shock length is ajustable many shocks can be adapted. contact Daughertymotorsports.com. he is a 1000R member and has shock kits and recomendations for us
Look at Jamie Daughtery Motorsports website. He has some rear shock options that I'm looking at doing. Jamie seems to really know his stuff. If you drop him a message on his site, he'll get back to you. He is also a member of this group.
