This front upper suspension arm pair is made for Team Losi SUPER BAJA models to support the knuckle and tighten front-end response. Supplied as one pair (2 pcs), the arms are CNC-machined from 6061 T6 aluminium to replace flexible plastic or stamped steel items when a firmer mounting point is required for more predictable handling.
The design uses pressed Delrin collars in the pivot bores to cut play and give a precise pivot fit, while stainless ball elements with matching rings and screws create corrosion-resistant joint surfaces. The geometry keeps original suspension kinematics but reduces flex under load to help maintain steering accuracy on rough terrain.
Fitment follows standard arm-swap steps: remove the factory arms, transfer any needed bushings or hardware, then install the replacement arms using the stock hinge pin and knuckle locations. CNC machining and anodising deliver repeatable dimensions and reliable fit when parts are correctly seated.
For drivers after a firmer front end and steadier steering on Super Baja rigs, these aluminium arms provide a durable, serviceable upgrade while preserving the stock suspension geometry.
