This is an aftermarket replacement pin set intended for ARRMA Talion 6S EXB scale models, supplied by GPM as part number MTV6/PIN49. The pins are machined from 4140 steel, heat-treated and blackened to resist wear under repeated loading in RC suspension systems. They replace factory part AR330194 and are sized 4x49mm for the outside rear lower suspension location.
These components form the pivot and retention point for the rear lower suspension arm, so correct seating and a secure press are required to preserve suspension geometry and consistent handling. Kits come pre-assembled where applicable, and a medium-strength thread locker is recommended on locknuts and related fasteners to reduce loosening during aggressive running.
Fitment is straightforward for anyone familiar with ARRMA chassis work: remove the rear lower arm retainers, remove the original pins, fit the 4x49mm replacements, then reinstall locknuts and torque to the vehicle specification. Confirm suspension travel and wheel alignment after fitting and check for smooth pivot action.
