For a stabilizer you want a Precision without a doubt. For a case saver, I use a TM design and like it, I have been using Primary drive chain and sprockets and I also like the stock ones, I run a Yoshimura for a pipe.
Stabilizer - I run the Fastway Pro Design. I had a CCP, it was ok but did not last long for me.
Case saver - I have had no issues with my UPP Poly set up.
Sprockets - No brand preference there, they all work for me.
Pipes - Am loving my DMC Force 4‘s after running the Big Gun EVO R set up. Better top end.
Levers - ASV Pro Pack. Wasn’t on your list but if you are going to ask about sprockets, let’s throw these in.
