Ready to upgrade your TRX4M crawler? This brass parts set is a game-changer for performance. It includes 2 steering knuckles, 2 caster blocks (C-hubs), and 1 steering link – all made from solid, corrosion-resistant brass. Why brass? It adds significant weight down low at the wheels, which lowers your rig's center of gravity. This means better traction, less tipping, and overall more stable crawling on rough terrain. They're direct replacements for the stock plastic parts, and installation is pretty straightforward if you're familiar with basic RC maintenance. Fits the TRX4M 1/18 scale Ford Bronco and Land Rover Defender models perfectly. The gold color looks slick, too. These are durable, essential upgrades for any serious crawler enthusiast looking to get the most out of their rig. Say goodbye to flex and hello to planted, confident performance. Your TRX4M will thank you. 🔧
