TRX4M owners, listen up - these INJORA brass caster blocks and steering components will seriously upgrade your RC crawler's performance! Made from high-quality brass with that sharp INJORA logo etching, they not only look fantastic but add crucial weight down low where you need it most. By replacing those plastic stock parts, you're getting enhanced durability and way better performance on tricky terrain. The added weight lowers your center of gravity dramatically, giving you better balance and traction when climbing over rocks and obstacles. This kit includes the steering link, caster blocks, and steering knuckle - everything you need for a comprehensive front-end upgrade. The brass construction means these parts can take the punishment of hard crawls without wearing out like plastic ones do. Installation is straightforward if you're comfortable with basic RC maintenance. You'll notice the difference immediately - less tipping, more controlled steering, and just overall more confident crawling. It's one of those upgrades that actually makes a noticeable difference in how your TRX4M handles challenging courses. If you're serious about getting the most performance out of your 1/18 scale crawler, these brass components are absolutely worth the investment. Your crawling buddies will be wondering how you're making those impossible lines look easy!
