- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3613-4008-0048:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals.

## Description

These 48mm Gecko® Wheels are constructed of high-grip silicone rubber which offers excellent traction against a multitude of surfaces. The spoke design allows the wheels to compress and conform around objects with ease. The wheels are non-directional which means that they will provide the same reliable results no matter which direction you spin them. The plastic center core gives this wheel great positive drive when installed on an 8mm REX™ shaft, leaving only the axial constraint up to you. The grippy surface and compliant design make this wheel the perfect finishing touch to your goBILDA® intake assembly.
