Ready to boost your TRX4M's performance? This GLOBACT brass upgrade set is a game-changer for your 1/18 scale crawler. It includes steering blocks, caster blocks, and axle covers—all CNC-machined from high-quality brass for extra durability and weight. The black brass finish looks sleek and adds a pro touch to your rig. Why brass? It lowers the center of gravity, giving your TRX4M Bronco or Defender way better stability on climbs and helping prevent rollovers. The set weighs about 55 grams total, with each piece precisely weighted: steering blocks at 10.6g each, caster blocks at 4.6g each, and axle covers at 12.4g. Installation is straightforward, and they swap right in for the stock plastic parts. You'll notice smoother steering, less friction, and more precise control on tricky terrain. Plus, they just look awesome—like a high-end upgrade should. Comes with all necessary screws. Whether you're a casual crawler or a serious hobbyist, these brass parts will take your TRX4M to the next level. Get ready to tackle those tough trails with confidence!
