LUK is an OEM Flywheel manufacturer for BMW. 

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.

Features and Benefits:

  • Top driving comfort
  • Absorbs vibrations
  • Prevents noise
  • Enables comfortable, low-revs driving
  • Saves fuel
  • Relieves crankshaft and gearbox

    Tough Chewer Approved but Not a Forever Toy
    Flavor Name: Original, Size: X-Large
    I do like this toy for what it is meant to do. It is definitely built for strong chewers and holds up way better than softer toys that get destroyed in minutes. The texture keeps dogs interested and gives them something to really work on, which helps with boredom and can support dental cleaning through chewing. It is one of those “finally something that lasts a bit” kind of toys for heavy chewers. That said, it is not something you just toss in and forget about forever. Like most hard nylon toys, it will wear down over time and should be checked regularly for rough edges or changes in shape. Some dogs will also go through it faster depending on how intense their chewing style is, so replacement will eventually be needed. Girl, this is one of those “it survives the chaos better than most, but you still need to keep an eye on it” situations.

    Clean teeth as well!!
    Flavor Name: Bacon & Chicken, Size: Small
    If your dog is a chewer or just bored, these bones are amazing. All of my dogs love and have loved Nylabones. I consider them a must to give your dog as an outlet to chew when bored or when in need of stimulation. Replace as necessary. I always have a pack on standby.
