I currently have a Valair single disk you speak of. Kevlar Ceramic rated for 500hp and it's been great. Pulled over 20k lbs with no issue. I'm actually gonna be selling it prob this next week as I just bought a Southbend DD to handle more power.
That's what going in my truck this weekend. I have absolutely had no issues with my Valair and have talked to Dan on his personal cell more than once. Great guy and great company just went with SB to give them a shot aswell. No offense Dan :thumbsup:you can't really go wrong with either, but the South Bend dual friction dual disk is pretty killer... quiet, engages like stock, holds tons of power
