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

Great rug, especially for the price!
Size: 30" X 20", Color: Black
This rug was perfect for our small bathroom. It acts as a rug for the toilet and for the bathtub at the same time. So far it is holding up nicely and has fantastic grip on our lvp flooring and is so soft on my feet! 10/10 would buy again!

Well-made liner that ‘s heavy & durable
Size: 72"W x 78"L (Pack of 1), Color: 1a. Clear
These Barossa Design Long Shower Curtain Liner is thick, sturdy, and looks and feels noticeably more durable than standard liners. The heavier weight helps it hang straight without clinging, giving the shower a clean, polished look. It does a great job keeping water contained, and the material feels strong enough to last through regular use without tearing or thinning out. The length is ideal for taller showers, adding extra coverage and protection.

Great Quality and Perfect for Creative Projector Effects
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
Although designed as a shower curtain liner, I ended up using this for a completely different purpose and it worked perfectly. I placed it behind my study window as a projection screen for Halloween videos, and the results were fantastic. The material allowed the projector image to display clearly while still diffusing the light nicely for a great effect from outside. The quality was much better than expected, the material felt durable, and it was easy to position and work with. This product turned out to be incredibly versatile and offered excellent value for the money. If you enjoy creative decorating ideas or seasonal displays, this works brilliantly as an inexpensive projection screen alternative.

Perfect length and actually stays in place.
Size: 72"W x 75"L (Pack of 1), Color: 1a. Clear
This liner solved a problem I didn’t realize was bothering me until I switched to it. The extra length makes a big difference—no more water sneaking out onto the floor or the curtain riding up while you’re showering. It hangs nicely and gives a cleaner, more finished look compared to standard sizes. The material feels thicker than the cheap liners you usually find, but not overly stiff. It drapes well and doesn’t stick to you while showering, which is a big plus. The magnets at the bottom actually work and help keep it in place against the tub, especially if you have any airflow in the bathroom. Installation was simple and the reinforced holes seem durable enough to last. Overall, it just does what it’s supposed to do without any fuss. For the price, it’s a solid upgrade and something I’d definitely buy again.

Well made
Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
The magnets hold well. The grommets are sturdy. The plastic is a bit thick and doesn't like to lie flat against the tub so it is constantly brushing you while you shower.
