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.
The role of these pins is to provide the pivot and retention point for the rear lower suspension arm; correct seating prevents unwanted play and preserves predictable handling. This kit may come pre-assembled where applicable, and the maker suggests using a medium-strength thread locker on relevant fasteners to reduce loosening from impacts or high-speed runs.
To fit: remove the rear lower arm retaining hardware, replace the factory pins with these 4x49mm pins, then refit locknuts and torque according to the vehicle manual. After replacement check suspension travel, wheel alignment and ensure pivot movement is free from binding.
