I have searched around in the polaris turbo thread and found mixed reviews as far as installing the SLP torque arm on turbo sleds. I have a 18 163 2.6 with a Silber kit. I like the turbo kit just the clutches are hot for my liking. I was thinking about trying the SLP arm then trying Indy dan kit next. I have read some people the motor was meant to move and others say it moves to much. I ride at 7500-10500. Thanks!
