So i bought CV tech clutches last year and have since upgraded with larger tires. I have been trying to get a hold of Airdam for over a month and no one seems to answer the phone or email. I have heard of Russel Coker tuning these clutches, does anyone know how to get ahold of him? Is there anybody else that is a CV Tech Guru? Our northeast mudding season is approaching fast and i would like to get some fine tuning done.
