The GPM RUS4030 rear shock tower for Traxxas 1/10 Rustler VXL is CNC machined from 6061 T6 aluminium to provide consistent stiffness and reduced flex under load. Multiple positioning holes allow precise changes to shock angle and tuning range, helping to refine handling and balance. The 3D streamlined machining concentrates material where it matters to improve durability while maintaining a refined finish.
