INJORA Black Brass Steering Link for TRX4M – CNC-Machined Upgrade, 12g, High Clearance

This INJORA black brass steering link is a CNC-machined upgrade for 1/18 TRX4M RC crawlers like the Defender, Bronco, K10 High Trail, and F150. Weighing 12 grams and featuring a high-clearance bend to avoid tire contact, it replaces the factory plastic part to help reduce flex and boost steering precision.

How does the high-clearance bend improve performance?

The link’s bend is shaped to clear the tire at full steering lock, preventing binding or rubbing during tight turns. This lets you push the suspension further without interference, which is especially useful on rough trails where maximum articulation matters.

What materials and craftsmanship are used?

Each link is precision CNC machined from solid brass, then black finished for a sleek look. The machining ensures tight tolerances, consistent geometry, and a smooth surface. At 12 grams, it adds a small amount of low-down weight to the front axle, which can help lower the center of gravity and improve stability on off-camber sections.

Which TRX4M models is this compatible with?

The steering link fits all TRX4M variants: Defender, Bronco, K10 High Trail, and F150. It directly replaces the stock plastic steering link without modifications. Note that it does not include mounting hardware; reuse the factory screws or purchase separately.

Key specifications

Frequently asked questions

Will this steering link fit the stock servo?

Yes, it is designed as a direct replacement for the factory plastic link and works with the stock servo horn and bellcrank. If you have upgraded to a different servo, verify that the link’s mounting holes align (center-to-center distance is not specified but matches OEM geometry).

Does the extra weight affect performance?

The 12-gram brass link adds unsprung weight low on the axle, which can improve traction and lower the center of gravity. Some drivers find this helps with hill climbing and side-hill stability. It does not noticeably slow steering response.

Can I use this link with aftermarket suspension arms?

Yes, the high-clearance design is independent of suspension geometry. It clears most aftermarket arms and tires, though very large tires (over stock diameter) may still contact the link; test fitment before reassembling.
