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.

COMP Cams Thumpr Hydraulic Roller Cam and Lifter Kits

COMP Cams is bringing the musclecar sound back, and it's nastier than ever! Few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle. In an ongoing quest to provide you with the performance and sound that you demand, COMP Cams' engineering team proudly introduces the Thumpr Series hydraulic roller cam and lifter kits. They are designed for use in engines that were originally equipped with flat tappet camshafts. The lobe profile and grind characteristics of these Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap. They're designed to maximize the rough-idling characteristics of the cams, giving you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. They are available in three different grind profiles. Each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. Thumpr Series cam and lifter kits feature a cutting-edge hydraulic roller design that delivers a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.
