Delrin collars for TT01 drift arm

This is an RC-scale Delrin collar set intended for Tamiya TT01 applications that use the TT055D drift arm. The set contains 4 pcs keyed for shaft location and spacing. Made from Delrin, these collars act as low-friction spacers and bearing seats where small axial adjustments and firm positioning are needed on drivetrain or steering shafts in drift setups.

Installation is straightforward on compatible TT01 shafts: slide the collar onto the shaft, position to the required location and secure using the original set screw or clip on the drift arm assembly. Check alignment with the mating hub and verify there is no binding through the range of motion before final tightening. Use aftermarket or original hardware already present on your chassis; no extra tools are supplied.

In tuning terms, Delrin collars are used to adjust endplay and lateral clearance without adding rotating mass, and they can help maintain predictable geometry when replacing worn plastic or metal spacers. Routine inspection for wear and debris is advised, and replacement is recommended if the collar shows significant scoring or loss of fit.
