[TMAN0950]

Hi, I have two R1 damper, one has a pulley made on it and one does not. All the numbers on both are the same but one has a 1 on it and the other has a 3. . will eather work on a R-1 thanks for your help

The one with the groove is Lark/Hawk, the other is Avanti. Both work on r1/r2, but depends on the car application.

Hi, thanks for the info. Are there pullies made that I could put the Avanti damper into a Hawk? Thanks Again Terry

I believe you would have to get a groove cut in the Avanti pulley to use it in a Hawk.
