TRAXXAS E-REVO POM Front and Rear Cupped Ball Collars ER021/DC by GPM  [ER021/DC]

POM cupped collars for controlled preload

This 8 piece front and rear set of cupped ball threaded collars is for TRAXXAS E-REVO and manufactured in POM (polyoxymethylene). The material provides good dimensional stability and low friction, suited to small parts that control wheel retention and linkage positioning.

Installation is direct: the collars thread onto the ball stud seats and use the supplied rubber O-rings to help lock the chosen position and reduce minor play. After installation, adjust each collar until the wheel rotates smoothly without axial play or excess drag.

Fit these collars where precise mechanical clearance and repeatable positioning are required on the E-REVO, for example at wheel studs or ball-ended linkages. They are a compact tuning component intended for RC use to help maintain consistent wheel performance as you tweak setup settings.
