Aluminium front knuckles for TRAXXAS Unlimited Desert Racer 1/7

This aluminium front knuckle arm set is an RC-scale replacement part made for the TRAXXAS Unlimited Desert Racer 1/7 platform. Machined from 7075-T6 aluminium, the arms give a rigid mounting point for the CVD and front suspension arms while accommodating larger inner bearings supplied with the kit. Multiple tie-rod mounting holes let you tune steering throw and ackermann without altering the steering linkage.

Installation is intended to be plug-and-play with the stock steering layout and uses the supplied fasteners and pins. The knuckles allow adjustment at the mounting to change arm angle and refine steering feel for different surfaces or handling preferences. The description and included hardware correspond to the items shipped in the package below.

For builders who want a stiffer front end on the Unlimited Desert Racer 1/7, these knuckle arms provide a durable aluminium upgrade with larger bearing accommodation and simple adjustability for tuning steering response.

Can I swap these in without modifying the stock steering parts?

Yes. The knuckles are designed for plug-and-play replacement on the listed TRAXXAS model and include the fasteners and pins needed for direct installation.

What benefit does 7075-T6 aluminium give over softer alloys?

7075-T6 offers higher stiffness and improved wear resistance versus common aluminium grades, helping the knuckle hold geometry under heavy steering loads.

Are the bearings included and ready to fit?

Yes, the listed bearings are included in the packing block and match the inner and outer races supplied with the knuckle kit.

How do I change steering characteristics with these knuckles?

Use the different tie-rod holes to vary throw and ackermann, and adjust the knuckle mounting angle to tweak steering responsiveness for different track conditions.

Will I need to machine or trim anything to install?

No additional machining is expected; the kit is supplied with the required screws, pins and bearings for direct fitment to the compatible model listed in the compatibility box.
