The GPM GT056 rear suspension arms are a precision engineered upgrade for the Traxxas 4WD GT4 TEC 2.0. Manufactured from 6061 T6 aluminium and supplied with delrin collars to minimise joint clearance, these arms improve repeatability and contribute to a more stable rear end. Multiple mounting points provide straightforward damper angle tuning for setup optimisation while retaining a compact, aerodynamic profile.
