GN-126 – Rubber Flex Disc – Mercedes Application – Bolt Circle Dia 90MM – Disc Width 26MM

GN-126 is a critical component for Mercedes vehicles, specifically designed to absorb torsional vibrations between the transmission output and driveshaft input. This Rubber Flex Disc plays a vital role in enhancing cabin comfort by significantly reducing noise, vibration, and harshness (NVH). If you’re experiencing symptoms like clunking on takeoff or vibrations at low speeds, it’s likely time to replace your flex disc.

Common failure signs include visible cracking or deformation of the disc, which can lead to increased NVH and compromised driveline performance. The GN-126 is compatible with various Mercedes models, including 200ER, 220ER, 230ER, 240ER, 250ER, 280ER, and 300ER. It features a bolt circle diameter of 90MM, a bolt hole count of 6, and a disc width of 26MM, making it a direct fit for these applications.

When installing the GN-126, ensure you check the bolt orientation and align the markings correctly. Torque the bolts to specification in a star pattern to avoid uneven stress. Regular inspection of the flex disc can prevent costly driveline issues down the line.
