The JAZRIDER JR-TRX4M01-BK brass steering blocks provide a simple, durable way to add useful front-end ballast to the Traxxas 1/18 TRX4M Bronco and TRX-4M Defender. They are aimed at hobbyists who want consistent handling gains without complex chassis changes.
Brass offers long life under normal trail conditions and resists deformation better than many lightweight alloys. The black finish reduces visible wear and helps the parts blend with stock components.
Fit with standard hand tools, check all fasteners after the first session, and keep the steering pivots free of grit. These blocks are designed for routine maintenance and straightforward part swaps.
