GN-102 – Rubber Flex Disc – Mercedes Application – Bolt Circle Dia 61MM – Disc Width 11MM

When your MERCEDES drivetrain starts transmitting clunks or shudder at low speed, the rubber flex disc is frequently the culprit. Part number GN-102 is a direct-replacement propshaft coupling built to exacting dimensional tolerances, restoring smooth torque transfer between the transmission output and the driveshaft flange.

Technical Specifications

Torsional Damping in Practice

A rubber flex disc does more than connect two flanges -- it acts as the drivetrain's primary torsional damper. When the engine fires each cylinder, a brief torque spike travels down the driveshaft. Without a compliant coupling at the transmission end, those spikes translate into audible noise in the cabin. The GN-102 is tuned for the torque characteristics and RPM range of MERCEDES vehicles.

Service and Replacement Guidance

Replace the flex disc any time you observe cracking, separation at the inserts, or visible rubber deterioration. Annual inspection is advisable on high-mileage vehicles. When sourcing a replacement, use only parts that match the original bolt circle and hole count -- aftermarket variations with even 1-2mm differences in bolt circle can cause index load imbalances that shorten bearing life throughout the driveline.
