Does any one have a HPD Shift Drum Conversion Kit $189, what does it do and do i do this instead of or in addition to the aggressive clutch Kit? is it bolt on or do i have to send something in to them?
I hear it is the best thing on an auto tranny ever done.

 

I tried getting one for my Scrambler . They said they were having legal problems so they couldn't sell it . I went with the AAEN roller clutch kit. Very easy to install yourself no machining reqiured. I like it has quick upshift along with excellent downshifting. It cost a little more than the HPD kit

 

thanks.
