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

POM threaded cupped collars for wheel retention

This 8-piece set of front and rear cupped ball threaded collars is made for TRAXXAS E-REVO and injection moulded in POM (polyoxymethylene). The material offers good rigidity and low friction for precision components used at wheel hubs and suspension link points.

Fitting is simple: the threaded collars locate on the ball stud seats and use the supplied rubber O-rings to help hold position and reduce play. After mounting, rotate each collar to achieve a balance where wheels turn freely without unwanted lateral movement, then seat the O-ring to lock the setting.

These collars are intended for points that need tight mechanical clearance and repeatable positioning on the E-REVO, such as wheel studs or ball link ends. They are a small, practical tuning part to help keep wheel response consistent as you change setup.
