Knuckle Arm Summary

Supplied as a matched pair for the TRAXXAS XO-1, this aluminium front knuckle arm is aimed at hobbyists tuning for track performance. The low-clearance fit reduces steering linkage slop to give a more precise and predictable response without changing chassis geometry.

Fitment is intended as a direct swap where original knuckle dimensions align. Typical installation involves removing the wheel hub assembly, fitting the new knuckle arm, checking pinion and hub alignment, then reassembling and setting steering throw and toe. Use this component when dialling in alignment and suspension settings for consistent handling.

Specifications

  • Item: Front Knuckle Arm - 1pr
  • Material: Aluminium
  • Model Number: XO021
  • Compatibility: TRAXXAS XO-1

Opt for this aluminium pair to tighten steering feel on XO-1 rigs; inspect linkage clearance and run alignment checks after fitting.

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

Is the pair compatible with stock XO-1 assemblies?

Yes when the stock knuckle dimensions are standard; measure the original part and compare before attempting the swap.

How does aluminium affect handling?

Aluminium reduces flex and maintains a consistent pivot point, which helps steering precision and repeatability during cornering sessions.

Any lubrication needed on install?

Lightly grease bearings and contact points as per usual RC practice; avoid excess grease near pivot fits that could attract dirt.

Can these reduce bump steer or scrub?

They are not a geometry change but tighter fits can reduce unwanted movement that contributes to inconsistent steering behaviour under load.
