Traxxas TRX-4M Bronco/Defender Brass Front Steering Blocks by JAZRIDER JR-TRX4M01-BK  [JR-TRX4M01-BK]

Front steering blocks for 1/18 TRX-4M

This is an RC-scale front steering blocks set produced by JAZRIDER for Traxxas 1/18 TRX4M platforms, supplied in a black finish with brass as the working material. The parts replace the standard front steering blocks on TRX4M Bronco and TRX-4M Defender 1/18 models and are intended for hobby use on scale trail crawlers.

Brass steering blocks change how the front axle behaves by adding mass and using a metal contact surface where the stock plastic parts normally sit. In practice this improves long-term wear resistance at pivot points and alters steering feedback, which can help drivers tuning front-end balance and steering effort on scaled trails.

Installation is straightforward for experienced hobbyists: the blocks are designed as direct-fit replacements for the specified 1/18 TRX4M Bronco and TRX-4M Defender steering knuckles and typically reuse the factory screws and hardware. After fitting, verify steering geometry and wheel alignment, and check that the pivot points move freely without binding.

Tuning notes: because brass adds rotating and unsprung mass at the front, expect slightly heavier steering feel and a different settling behaviour on rocky or uneven surfaces. Use this part as a component in a broader tuning approach—adjust tyre choice, suspension preload and servo endpoints to match the new front-end characteristics.
