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

Love the quality and matte black color
Size: 6 Inch, Color: Black, Size: 6 Inch, Color: Black
I love the color how it is not shiny and a matte black. This gives a modern look to any decor. It is very sturdy and attaches with six different screws. Great quality for the price.

The sturdiness of these brackets and the quality are so good. I was worried due to other reviews I had read but these did not disappoint. They are beautiful and perfect length and weight. They are angles perfect for our shelves and a great value for as many as you get.

Beautiful! Exactly what I was looking for!
Size: 12 Inch, Color: Gold, Size: 12 Inch, Color: Gold
Sturdy, well contructed, and an even natural gold finish. Come with two different wall anchors and brass screws. Installation is easy. Just take your time measuring and drilling holes. I purchased finished white shelves from the closet section of home depot, $7 a piece. Gives them a nice finished look. They measure 3/4โ€ x 11.75โ€ x 24โ€. The brackets are 12โ€ deep so there is a slight gap at the front but its not noticeable. Highly reccomend.
