INJORA +7mm Planet Front & Rear Axles with Scale Hydraulic Steering for 1/18 TRX4M Upgrade (Black)

Upgrade overview

Enhance your 1/18 TRX4M with INJORA’s +7mm Planet Front and Rear Axles. This kit combines a scale hydraulic steering system with a planetary-inspired differential housing for a more realistic look and feel on challenging terrain. The front axle carries brass steering knuckles for added weight and grip, while double joint shafts help keep wheel motion smooth during sharp turns.

Expected benefits are achieved through thoughtful engineering rather than promises of guaranteed outcomes. The design emphasizes a wider stance, improved steering feel, and durable gearing, making it a compelling option for crawlers that see mixed trails and rock ridges.

Key features at a glance

• Scale Hydraulic Steering System uses a double-ended ram for a realistic, responsive look and feel.
• Planet-inspired differential housing is CNC-machined for precise alignment and a lifelike chassis profile.
• Double Joint Shafts reduce wheel vibration when turning at extreme angles, promoting steadier tire contact.
• Brass Steering Knuckles add front-end weight for enhanced traction and climbing efficiency.
• +7mm Extended Width broadens the stance per side for improved stability and control on uneven ground.
• 12T & 24T Alloy Steel Helical Gears deliver smooth meshing and durability under demanding use.

What you may notice on the trail

On ascents and rough surfaces, the wider stance can contribute to a more planted feel, while the scale steering components provide a tactile, responsive response to steering inputs. The heavier front end and robust gears are designed to withstand demanding crawls, potentially helping you negotiate tricky rocks with more confidence. The combination of features is tuned for realism and reliability, not guarantees.

Expect improved steering control during traverses and better front-end feedback when negotiating ledges or roots. The integrated details are aimed at enhancing the scale appearance and may contribute to steadier handling in real-world crawling scenarios.

Compatibility and setup notes

• Note: Not compatible with the TRX4M stock chassis.
• Steering knuckles and double joint shafts are not compatible with the TRX4M stock axle housing.
• Compatible with INJORA INJS2065, INJS11, and TRX4M stock servos.

Before upgrading, check space for the wider front and rear feet, and plan for proper mounting. The 7mm per side width increase may require minor clearance adjustments in some chassis configurations.
