Indy´s Rocker Arms

Hi Guys,

a shop over here sells some Aluminium Roller Rockers 1,6 Ratio supplied by Indy. The part no. is like 360-R4-4 SDR1.6, i was not able to find these number on the indy hp or in their catalog, only these: 360-R4-4SR.
According to the pic from my dealer these are red anodized, non bushed and ride directly on the shaft (no needle bearing)......did not know about these, never seen before. Anyone has got some experience with this part?

I´d like to upgrade to 1,6 Ratio Rockers next year and search for reasonable priced rockers, but want to stay away from cheap crap....Thanks for info!
