Amazing.
This clutch does everything described. I thought it would be a bit grabby with two discs but its driving like a 4 cylinder car. With the dual flywheel on the factory clutch I almost needed a seat belt with the vibration at idle. Now you cant even tell the truck is on besides the straight pipe. My only complaint is the mounting situation for the hydraulics. They want you to sheet metal screw it to the firewall. That's just stupid. I built a bracket coming of the sheet metal for the cowl and riveted it to the bracket. Now it is removable if need be without wearing holes out in the firewall.
