Traxxas TRX-4M Front Steering Block Upgrade, Brass - JR-TRX4M01-BK by Jazrider  [JR-TRX4M01-BK]

Brass steering blocks for Traxxas 1/18 TRX4M

This RC-scale steering block set comes in a black finish with brass components for Traxxas 1/18 TRX4M platforms. The JR-TRX4M01-BK units replace the stock front steering blocks on TRX4M Bronco and TRX-4M Defender 1/18 models and are suitable for hobbyist scale crawler setups.

Brass alters front axle behaviour by increasing mass and creating a metal contact surface where plastic normally sits, improving wear resistance at pivot points and changing steering feedback to help with front-end tuning.

Fitting is intended to be direct: these parts match the listed 1/18 TRX4M Bronco and TRX-4M Defender steering knuckles and generally use factory screws and hardware. After installation, check alignment and pivot freedom to ensure correct operation.

Note on handling: added rotating and unsprung mass at the front will typically make steering feel heavier and change how the vehicle settles on rough terrain. Adjust tyres, suspension preload and servo endpoints as part of a broader setup to achieve the preferred handling balance.
