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

POM cupped seat collars for precise endplay control

This product is an 8pcs set of front and rear cupped ball threaded collars intended for TRAXXAS E-REVO applications, produced in POM (polyoxymethylene). The chosen polymer delivers firm dimensional stability and low running friction for small components used at wheel hubs and linkage balls.

Installation is straightforward: the collars thread onto ball stud seats and use the supplied rubber O-rings to help lock position and damp minor play. Once fitted, rotate each collar to find the balance where the wheel runs freely yet has no slop, then secure with the O-ring.

Use these collars wherever repeatable axial clearance and reliable positioning are required on the E-REVO chassis, for example at wheel studs or ball joint ends. They are a compact tuning item for RC setups and aid consistent wheel behaviour when adjusting alignment or bearing preload.
