Hey I have a 2005 f7 with the act drive system on it, the sled has about 5000 miles on it and my secondary just failed due to excesive wear ot the part attached to the Helix on the back. I have ordered a new clucth but am wondering if anyone knows how to prevent that from happening again. If you would like to e-mail me that is conrads-383dodgechallenger@hotmial.com Thank you.
