HPI Racing BAJA Wheel Spacers Delrin BJ057/DC by GPM  [BJ057/DC]

Precision Delrin collars for BJ057 setups

This kit includes four Delrin collars cut for BJ057 use, listed as part number BJ057/DC. They are intended for hobby-grade RC models where small, accurate spacers are used to set hub position and keep axle clearance consistent.

Delrin (acetal) provides low friction and reliable dimensional stability under typical hobby temperatures, making these collars ideal for placement between hubs, bearings, or on axle journals. They serve as positional components rather than load-bearing hardware.

Installation suits anyone familiar with wheel hub work: position the collar on the axle or inside the hub bore to obtain the desired spacing, then secure the hub as per the vehicle manual. Confirm free rotation and correct bearing preload after fitting.

• Role: set and hold axle spacing, align wheel hubs, limit lateral movement.
• Material note: Delrin is good for sliding fits and repeated assembly cycles.
• Quantity: 4 pieces supplied as indicated by the part number.
