INJORA 53mm 6g Shocks for TRX4M/TRX4MT – Threaded Damper Upgrade for 1/18 RC Crawlers

Upgrade your TRX4M/TRX4MT with precision damping

Elevate the control and realism of your 1/18 RC crawler with INJORA’s 53mm, 6g shocks. Designed for TRX4M Defender, Bronco, K10 High Trail, F150, and TRX4MT variants, these dampers blend sturdy metal construction with tuned spring options to create a smoother, more confident ride over varied terrain.

These dampers are built to deliver consistent feedback, letting you feel each obstacle as you crawl, climb, and maneuver. The result is improved on-trail feel and predictable handling, making it easier to place your wheels where you want them without overreacting to abrupt bumps.

What’s included and how it helps your setup

• Two spring rates included (0.45 mm and 0.5 mm). Each spring is 43 mm long and adjustable to match your chassis weight and terrain.
• CNC machined aluminum shock bodies for robust protection and long-lasting durability in rugged environments.
• Nylon bottom rod end with a telescopic design to maximize travel, up to 13.5 mm, helping you clear uneven sections with more sequence control.
• Threaded shock bodies for quick pre-load adjustments, enabling smooth, consistent damping without complex disassembly.

Fitment, setup notes, and what you’ll need

• Compatible with TRX4M 1/18 Defender, Bronco, K10 High Trail, F150, and TRX4MT RC Crawlers.
• Note: Shock absorber oil is not included. Installation details are provided in Figure 6 for reference.

Real-world use often means balancing weight, speed, and terrain. With the dual springs, you can fine-tune stiffness for different rigs or trail conditions, while threaded pre-load helps you dial in the initial resistance. The aluminum bodies offer a blend of strength and reduced flex under load, contributing to steadier line management when traversing rocky sections or rutted dirt roads.

Whether you’re dialing in low-speed precision on technical sections or aiming for smoother transitions between climbs, these shocks are designed to be a practical upgrade that complements your existing TRX4M/TRX4MT build. While they do not guarantee specific performance outcomes, they provide tangible options to tailor damping characteristics and travel to your preferred crawling style.
