What it is 1 x hard aluminium alloy 25T M3 steering link servo arm horn for 1/10 scale crawlers such as TRX-4. A metal upgrade part. Why you need it - Stronger than plastic horns, built for durability under rock crawling loads. - Double mounting holes provide flexible fitment and better alignment with different linkages. - M3 threaded joints allow secure, smooth connections and easy installation. - Gold anodized finish adds visibility and a premium look without compromising performance. Specifications - Material: CNC aluminium alloy, gold finish - Spline: 25T - Thread: M3 - Mounting: double holes - Compatibility: fits 1/10 scale crawlers using a 25T M3 servo horn (e.g., TRX-4) How it helps - Improves steering durability and resists wear on rocky trails. - Maintains accurate steering geometry under load, reducing play and slop. - Quick replacement or upgrade option with standard hardware. Use scenarios - Upgrade the front steering on a TRX-4 or similar 1/10 crawler after rough rock crawling to improve reliability. - Replace a worn plastic horn on a 1/10 crawler to restore steering precision and strength. - Keep as a spare part for field repairs during long crawls, enabling fast swaps and minimal downtime.
