Traxxas TRX-4M Front Brass Steering Blocks for Bronco and Defender - JR-TRX4M01-BK by Jazrider  [JR-TRX4M01-BK]

Brass front steering blocks for 1/18 TRX4M

This RC-scale steering block set is supplied in a black finish and uses brass components for Traxxas 1/18 TRX4M platforms. Part number JR-TRX4M01-BK replaces the original front steering blocks on TRX4M Bronco and TRX-4M Defender 1/18 models and is designed for scale trail crawler use.

Brass steering blocks alter front axle behaviour by adding mass and providing a metal contact surface where stock plastic parts normally contact. This improves long-term wear resistance at pivot points and changes steering feedback, which is useful when tuning front-end balance and steering effort on scaled trails.

Installation is straightforward for experienced hobbyists: the blocks are made 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 confirm that pivot points move freely without binding.

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