Engineered as a durable, model-scale adjustable servo arm for the TRAXXAS TRX4 Trail Crawler, this 6061 T6 aluminum horn is supplied as a 7pcs set. The straight-arm profile and clear adjustment graduations support repeatable steering setups and dependable mechanical performance under trail conditions.
Installation follows standard servo horn replacement steps: remove the original, fit the new arm to the servo spline, and secure with the included stainless fasteners. The 20-25mm hole pattern permits incremental changes to steering leverage and throw without additional fabrication, making chassis tuning faster and cleaner.
