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.

South Bend Clutch Hydraulic Assemblies
It's common for clutch hydraulic systems to become aged or weak, meaning you won't be able to select gears in the transmission. Even if your hydraulics are still working properly, if you're upgrading the clutch in your truck (or plan to), it might be time to invest in a heavy-duty hydraulic assembly from South Bend Clutch. Some factory hydraulic assemblies aren't up to the task of handling a dual-disc or even a stronger single-disc clutch. Purchasing upgraded hydraulics at the same time you order your performance clutch is highly recommended. South Bend Clutch hydraulic assemblies are engineered to enhance your vehicle's performance. They are made to stringent quality standards to ensure exceptional durability and years of trouble-free service. The kits are complete, typically including a master cylinder (adjustable on select models), slave cylinder, remote reservoir, and braided stainless steel hoses. South Bend Clutch replacement hydraulic assemblies are ready to work hard and play hard--just like your rig.

LuK RepSet 2CT Clutch Kits
An increasing number of vehicle manufacturers are using double clutch transmission technology, enabling comfortable gear changes without interruption of traction power, while at the same time reducing fuel consumption and CO2 emissions. Like almost every clutch, the double clutch can also wear out. However, replacement is not possible without special tools. This is because the double clutch is firmly meshed in the gearbox bell and must be removed together with the gearbox. LuK RepSet 2CT clutch kits offer a unique repair solution for dry and wet double clutches. With a LuK kit and the corresponding special tool, repair shops can repair double clutches quickly and professionally. Besides the double clutch, LuK RepSet 2CT kits contain all the precisely matched components in OEM quality which are necessary for the replacement of the respective double clutch system. These include guide sleeves, retaining rings, fixing screws and lever actuators, or engagement levers and engagement bearings. Features to note: * For dry and wet double clutches * Includes all parts needed for the repair * OE quality and perfectly coordinated * Safe mounting due to simple installation instructions * High-quality special tool for the perfect repair
