This is an RC-scale wheel hex spacer set produced for the Axial Racing Yeti platform, supplied as a 2pcs set in Delrin material with a +10mm thickness to shift wheel offset outward. The parts are intended to change track width and clearances on the model, not for full‑scale vehicles.
Functionally the wideners move the wheel mounting face outward by 10mm per side, which affects wheel clearance, potential rubbing with suspension or bodywork, and the handling balance at chassis level. Use them when you need controlled increases in track width to fine‑tune cornering feel or to prevent wheel interference with aftermarket tyres or beadlocks.
Installation is straightforward on the Yeti hex hub system: remove the wheel and existing hex, fit the Delrin widener onto the hub, then reinstall the wheel and retainers using the original fasteners. Verify thread engagement and wheel centring before running, and check for any contact with the suspension or body after installation.
