Diesel trucks are designed for towing heavy loads. If your rig is running 500 to 650 hp, then Valair Performance Quiet Street Dual Disc clutch kits are the way to tow. They feature tough heavy-duty parts, strong pressure plates, and a nodular iron flywheel. These kits are not intended for racing or competition use. Quiet clutch kits eliminate floater plate rattle when the clutch is pressed in, but gear rollover noise is inevitable when changing to a solid mass flywheel. It's often heard when the vehicle is under load at low rpm or idling, and it sounds like marbles in the transmission. Please educate yourself before purchase. Towing is tough on your vehicle—keep the pressure high and the shifts solid with a Valair Performance Quiet Street Dual Disc clutch kit, available for a variety of specific transmission applications.
