GN-140 – Rubber Flex Disc – Mercedes Application – Bolt Circle Dia 90MM – Disc Width 29MM

GN-140 is a critical component in the driveline of Mercedes vehicles, specifically designed to absorb torsional vibrations between the transmission and driveshaft. This rubber flex disc significantly reduces noise, vibration, and harshness (NVH) in the cabin, enhancing the overall driving experience. With a bolt circle diameter of 90MM and a disc width of 29MM, this flex disc is tailored for Mercedes applications, including the 250ER and 280ER models.

When installed, the GN-140 flex disc compensates for minor angular misalignments without the need for a universal joint, making it a vital part of the driveline system. It’s crucial to monitor for signs of wear, such as clunking on takeoff or vibrations at low speeds, which may indicate that the flex disc is cracked or hardened. Regular inspection can prevent further driveline issues.
