Valair Performance Quiet Street Dual Disc Clutch Kits
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.

Auburn Gear Select-A-Loc Differentials
Auburn Gear Select-A-Loc differentials maximize your vehicle's traction with on-the-go system engage. These electronically controlled traction-enhancing differentials are selectable lockers offering the traction control of a limited-slip differential and a full-locking differential--all in one! When locker switch is off, the clutch pack activates the limited-slip mode. As torque increases, the separating forces within the differential gears increase, causing the clutch pack to be compressed, in turn providing bias torque to the highest traction wheel. When the locker switch is turned on, electronic current is sent to the electromagnetic coil which locks the axles together. Auburn Gear Select-A-Loc lockers feature a unique cone-clutch design with gearing made from aircraft-quality 9310 heat-treated billet steel for tough-as-nails strength. The lockers operate quietly without any shift fork or pins to line up to change the locker mode. With a limited-slip mode for on/off-road excitement and a true locker mode for the quarter-mile or nasty off-road terrain, Auburn Gear Select-A-Loc differentials deliver superior traction capabilities on the street, at the track, or off-road.
