This Arrowmax part is an RC-scale front upright arm sold as a 2 pcs set intended for Mugen MTX series chassis, including MTX-5 models. It serves as the steering knuckle replacement that locates the front wheel carrier and links steering inputs to the suspension.
Compatibility follows the Mugen MTX family designation from the source listing, so installers should expect this part to replace the stock front upright on MTX-5 based touring or on-road setups. The package count is 2 pcs which covers a left and right side replacement when needed.
Installation is standard for front uprights: remove wheel, hub, and steering linkage as required, swap the upright and reinstall pins or hardware used by the MTX-5 assembly. In practice this part is used for routine maintenance or for modest tuning changes that affect steering response and front suspension geometry without altering other chassis components.
The tone here is technical and neutral; this is an RC spare/hop-up component intended for track or practice use on compatible Mugen MTX platforms.
