Chevrolet Sonic Clutch Systems

Clutch Slave Cylinder Assembly The Valeo Clutch Release/Slave Cylinder Assembly is original equipment quality and maintains the equivalent fit and performance as the OE part it replaces.

Product Features:

• long life span
• maintenance-free due to permanent lubrication
• compact construction
• Automatic readjustment
• low pedal forces and wear
• weight reduction
• no traction force through hydraulic load on bolts

No other clutch kit supplier can offer components that exceed the OE quality that Valeo offers. Many program repackagers do not offer high percentages of OE specified clutch covers and discs. You can expect long life and smooth engagement from Valeo’s clutches because of our focus on quality. Valeo’s kits contain every component that a technician needs to change out a clutch. Each kit contains a clutch disc assembly, pressure plate cover assembly, release bearing, grease pack, and installation guide. Also included when necessary are a pilot bearing, and technical service bulletin. Valeo’s kits use packaging that is state of the art to ensure that the product arrives and remains free of damage right up to the time it is installed in a vehicle. The extra durable locking tabs ensure product security within its packaging until it is removed for final installation.

Product Features:

• OE Quality and direct fit application.
• Long life and smooth engagement.
• Clutch supplier worldwide to the Original Equipment Manufacturers.
• Valeo’s kits contain every component that a technician needs to change out a clutch.

LuK: Don’t gamble – stay with the original DMF! The DMF prevents damages solid flywheels may cause. The Dual Mass Flywheel (DMF) is individually fine-tuned for every type of car. The risks of using solid flywheels are numerous – from increased wear of engine mounts through gearbox failure to damaged crankshafts.

LuK: New flywheels are a smart alternative! The flywheel is an integral part of clutch replacement. It must provide a smooth, flat surface for proper clutch operation. Pairing your clutch set with a new flywheel is a smart, cost-effective alternative to resurfacing. All new – never remanufactured – every component is engineered and manufactured to OE specifications, including ring gear and dowel pins.

LuK dual-mass flywheels absorb engine vibrations before they are transmitted to the driveline where they can create gear rattle. These units feature a built-in damper designed to isolate engine torque spikes and prevent transmission damage. By design, dual-mass flywheels cannot be resurfaced. This all makes the LuK dual mass flywheel the ideal solution. With one drawback: the higher the mass reactance of the vibrating masses, the more excessive the resonance increase and associated torque peaks. With the dual mass flywheel, this would be easily perceived when starting and stopping the engine; much more easily than with a conventional clutch system. Additionally: the smaller flymass of the engine has less of a stabilizing effect on the speed fluctuation of the engine. Thanks to decades of experience in clutch building, the LuK specialists were able to find an excellent solution to this problem. An additional damping device effectively prevents resonance overload. In normal operation, however, this additional damping device has no function and the torsional vibrations of the engine are filtered out by spring dampers. Friction and spring rate – the correct ratio is important. For optimal vibration isolation and soft resonance passage when starting and stopping the engine, the ratio between friction and spring rate must be optimal. The length of the springs is a key factor: The softer a spring, the more efficiently vibrations are isolated. The extra-long springs of the latest generation of dual mass flywheels significantly reduce the spring rate compared to a first generation dual mass flywheel. In routine driving operations, excessive resonance increases are kept almost completely away from the gearbox.
