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.
Functionally these pins act as the pivot and retention point for the rear lower suspension arm, so correct fit and a tight press are important to maintain consistent suspension geometry and predictable handling. The package is supplied pre-assembled where applicable, and the manufacturer recommends using a medium-strength thread locker on associated fasteners to prevent loosening during bashing or high-speed runs.
Installation is straightforward for anyone familiar with ARRMA chassis servicing: remove the rear lower arm retaining hardware, swap the factory pins for these 4x49mm pins, reinstall locknuts and torque to the vehicle's recommended values. Verify suspension travel and wheel alignment after replacement and check for any binding at the pivot points.
