INJORA Front/Rear Planetary Axles w/ Scale Hydraulic Steering: TRX-4M

Scale Hydraulic Ram Steering

The simulated double-ended hydraulic ram steering system delivers an authentic scale look while improving steering control and responsiveness. Paired with brass steering knuckles, it adds beneficial front-end weight for increased traction and more confident turning during technical crawling.

Planet-Inspired Straight Axle Design

Each straight axle features a CNC-machined, planet-shaped differential housing for exceptional scale realism and precision. Double joint shafts minimize outer wheel vibration at extreme steering angles, while the +7mm extended width improves stability and control across both front and rear axles. Durable 12T and 24T alloy steel helical gears ensure smooth power delivery and long-lasting reliability.

Ultimate Crawling Upgrade

Engineered as a complete front and rear straight axle system, this set enhances handling, durability, and scale authenticity without relying on portal-style ground clearance gains. Lightweight aluminum housings and steering links, combined with brass and steel components, create a balanced upgrade ideal for serious hobbyists and detailed TRX-4M® builds.
