Injora +4mm Planet Axles with Brass Steering Knuckles for the TRX-4M

New from Injora is their +4mm Front and Rear Planet Axle Set with Brass Steering Knuckles for the Traxxas TRX-4M. If you’ve been eyeing Injora’s 1/24 Planet Axles and wished they could be upscaled for the 1/18-scale TRX-4M, consider that wish granted.

Designed non-stock TRX-4M chassis options, this set of axles brings scale looks along with added durability to your smaller-scale crawler. The axle set includes a lay-down servo mount (which is not compatible with the stock TRX-4M chassis), two optional short drag links for various steering setups, and brass steering knuckles (front axle) to help improve traction.

The axle housing is made of aluminum and features a black finish. The planet-shaped diff pumpkin gives these axles a realistic appearance, making them an excellent choice for scale builders.
