Technical Overview

This pair of aluminium front knuckle arms is supplied for the TRAXXAS XO-1 and is intended for hobbyist performance tuning. CNC-style machining yields a tight fit to reduce free play between the steering linkage and knuckle pivot, producing improved steering repeatability without altering baseline chassis geometry.

Intended as a direct-fit replacement when original knuckle dimensions conform, installation follows the standard removal and refit sequence: remove hub hardware, replace the knuckle arm, verify pinion engagement and hub alignment, then reassemble and set steering throw and toe during vehicle setup. The component is suitable as a precision tuning element when optimising steering feel and repeatability for track conditions.

Specifications

Just finished building a 4-tec 2.0 with GPM parts. SOOO beautiful. After having a bad experience building a wltoys this summer it was nice to once again do another build using GPM parts. The website is nothing to brag about but, the parts are top quality.

Once again it was a pleasure dealing with GPM customer service to inquire about a part. GPM was able to fill my order in a timely manner. Excellent communication from customer service. Thanks GPM!

Very good service. Website is nice, simple, and easy to navigate. Order processing went fast and shipping was extremely well-handled. With mail notifications each step of the way. The extra packaging option is definitely worth the money for overseas shipp

What tolerances should I expect from these knuckles?

Expect reduced play compared with common injection-moulded parts; the parts are intended to deliver consistent pivot alignment and minimal lateral movement at the steering pin.

Are any preparation steps needed before fitment?

Clean mating surfaces, verify bearing and hub condition, and check the stock knuckle dimensions to ensure correct fit prior to installation.

How should torque be applied to mounting fasteners?

Use controlled torque appropriate for small RC fasteners to avoid deformation; tighten incrementally and check free steering movement throughout the process.

Will these parts affect other suspension settings?

They are not intended to change geometry, but after fitting you should re-validate toe, caster and steering throw as part of routine setup verification.
