INJORA Front & Rear Axles Set +4mm Extended Aluminum for TRX4M 1/18 RC Crawler

Upgrade your TRX4M with INJORA Front & Rear Axles Set

Turn your 1/18 TRX4M crawler into a steadier, more capable climber with INJORA’s Front and Rear Axles Set. The kit features +4mm per side extensions, adding a total of 8mm to the overall length. This wider stance can translate to improved balance on uneven terrain, helping you approach obstacles with more control and confidence. The axles are CNC machined and finished in black anodize for a crisp, durable look that stands up to the wear of adventurous crawling sessions.

Designed with serious trail use in mind, these axles pair a robust aluminum build with precise engineering. The result is a component that stands up to repeated flexing and torque, while maintaining smooth operation as you trace over rocks, logs, and ruts. The kit is tailored for the TRX4M Bronco, Defender, and K10 models, delivering a cohesive upgrade path for enthusiasts who want to refine their 1/18 scale crawler without sacrificing reliability.

Installation and compatibility

Pre assembled components are designed for straightforward installation, with all necessary hardware included. Note that the extended axle housings change the mounting geometry, so these axles are not compatible with the original TRX4M steering links and dogbone shafts. If you plan to upgrade, verify fitment with your current steering components before install.

Real world use and expectations

In real world crawling scenarios, the broader track can contribute to more stable handling when negotiating ledges and rough terrain, while the longer overall length may influence cornering dynamics. This upgrade emphasizes robustness and a clearer upgrade path for TRX4M owners, offering a potential performance uplift without guaranteeing specific results.
