GD-90 – Rubber Flex Disc – Bmw Application – Bolt Circle Dia 50MM – Disc Width 20MM

GD-90 is a critical component for BMW vehicles, specifically designed to absorb torsional vibrations between the transmission output and driveshaft input. This flex disc features a bolt circle diameter of 50mm, four bolt holes measuring 8mm each, and a disc width of 20mm. It’s essential to ensure that you use the correct configuration, as even slight variations can lead to performance issues.

One of the standout features of the GD-90 is its ability to compensate for minor angular misalignments without the need for additional universal joints. This capability not only simplifies installation but also reduces NVH (noise, vibration, harshness) in the cabin, leading to a more comfortable driving experience. If you notice clunking on takeoff or vibrations at low speeds, it may be time to inspect the flex disc for visible cracking or deformation.

When installing the GD-90, ensure proper bolt orientation and alignment according to the manufacturer's specifications. Torque the bolts in a star pattern to avoid uneven stress on the disc. Regular inspection for cracks at the reinforcement sleeves is recommended to maintain optimal performance. Remember, using the correct flex disc like the GD-90 is crucial for the longevity and reliability of your BMW's driveline.
