TRX4M owners, listen up! If you're looking to seriously upgrade your little crawler's performance and looks, this GLOBACT aluminum and brass axle set is a game-changer. It's a complete front AND rear axle assembly made specifically for the 1/18 scale TRX4M models like the Bronco, Defender, K10 High Trail, and F150. Why upgrade? Two big reasons: weight and strength. The axles use a combination of CNC-machined aluminum for the main housing and heavy brass for the critical parts like the steering blocks, caster blocks, and steering links. All that brass adds a significant amount of low-down weight to your rig. This lowers the center of gravity massively, which makes your crawler WAY more stable on steep inclines and rocky terrain – it'll grip better and be much less likely to tip over. Plus, the metal construction is just stronger and more durable than the stock plastic parts, so it can handle more abuse. The set comes in a cool red finish and includes everything you need: both axles, all the brass components (steering blocks, caster blocks, links), axle covers, drive shafts, and even the steel axle gears. It's a complete bolt-on kit. You just swap out your stock axles for these, and you're done – no hunting for extra parts. It's a cost-effective way to get premium performance and that awesome, detailed look under your truck.
