Precision machined knuckles for low-speed control

This 14pcs aluminium front knuckle arm set is tailored for TRAXXAS TRX4 Trail Crawler scale use, providing extra support to steering linkages and internal front knuckle gears to maintain steady gear runs during technical crawling.

Components are CNC-machined from aluminium 6061 T6 and finished for clean geometry that resists deformation under load while delivering a solid metal touch. The kit serves as an aftermarket replacement to minimise play at knuckle pivots and to preserve smooth gear engagement at crawl speeds.

The supplied fasteners indicated by the product source are stainless steel screws in assorted sizes for mounting; confirm the item counts in the box and use correct thread engagement and locking practices when installing.

rating
The quality is good and both the delivery and the reception of the order, fast. I can not give more stars, because the price of each component is high, the cost of shipping very high, discounts for good customer null, and generic discounts, to use only

Are the mounting screws included?

The product listing shows stainless steel screws in various lengths are included; open the package to check the exact quantities and sizes before you begin fitting.

Will these improve durability?

Aluminium 6061 T6 offers greater stiffness than many stock plastics, reducing play at pivot points, though correct installation and torque settings are important to avoid stress concentrations.

Do I need to change other suspension parts?

Not necessarily, but after fitting you should recheck steering geometry and servo endpoints; in some setups a heavier servo or different link lengths may be used to match the firmer knuckles.
