Traxxas TRX-4M Bronco & Defender Front Brass Steering Blocks for 1/18 - JR-TRX4M01-BK by Jazrider  [JR-TRX4M01-BK]

1/18 TRX4M brass steering block upgrade

This RC-scale front steering blocks set is finished in black and constructed from brass for Traxxas 1/18 TRX4M platforms. The JR-TRX4M01-BK components replace the stock 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 alter front axle dynamics by adding mass and supplying a metal contact surface where original plastic parts sit. This provides better wear resistance at pivot points and changes steering feedback, which helps drivers when tuning front-end balance and steering effort for scale trails.

Installation guidance: these blocks are produced as direct-fit replacements for the stated 1/18 TRX4M Bronco and TRX-4M Defender steering knuckles and normally make use of factory screws and hardware. After fitting, inspect steering geometry and wheel alignment, and ensure pivot points move freely without binding.

Practical tuning note: because brass adds rotating and unsprung mass at the front, expect a slightly heavier steering feel and a different settling action on irregular surfaces. Use this upgrade alongside tyre, suspension preload and servo endpoint adjustments to achieve the desired handling characteristics.
