HPI Racing BAJA BJ057 Delrin Collars by GPM BJ057/DC  [BJ057/DC]

Delrin collars for BJ057

This aftermarket set delivers four Delrin collars designed specifically for BJ057 use, supplied by GPM as part number BJ057/DC. The parts are intended for RC-scale models where small, precise spacers are needed to control hub position and axle clearance.

Delrin (acetal) offers low friction and good dimensional stability at typical hobby temperatures, making it suitable for collars that sit between wheel hubs, bearings, or on axle journals. These collars act as passive location components rather than load-bearing replacements.

Installation is straightforward for experienced hobby technicians: slide the collar onto the axle or into the hub bore to establish desired spacing, then secure the hub assembly per the chassis manual. Verify free rotation and correct preload after fitting.

• Role: maintain axle spacing, locate wheel hubs, reduce lateral play.
• Material note: Delrin suits sliding fits and repeated assembly cycles.
• Quantity: 4pcs included as indicated in the product name.
