These Delrin hex wideners are made to fit the Axial Racing Yeti wheel hex hubs and add a precise +5mm offset to alter wheel track. The kit is supplied as a 2pcs set sized for standard Yeti hex hubs and is intended to give a consistent change to wheel spacing for setup tuning.
Typical use is for fine tuning handling and tyre clearance on scale off-road courses, where a small increase in track width can change lateral stability and reduce tyre-to-body contact. The wording remains specific to compatibility with the Yeti family and does not imply OEM origin.
Fitting is simple: slide the widener onto the wheel hex so it sits between hub and wheel, then tighten the wheel nut while checking adequate thread engagement and secure fit before running the model.
