Axial EXO Precision Rear Rim Frame - Nylon Inner with CNC-Ready Alloy 5-Star Beadlock EX0503R by GPM  [EX0503R]

Technical overview of the EXO rear rim assembly

This rear rim frame kit is engineered for Axial EXO applications and carries part number EX0503R. The assembly couples a dimensionally stable nylon rim frame with robust alloy five-star beadlock rings, supplied as a 1 pr set for direct rear-wheel replacement or upgrade on EXO chassis platforms. The section below focuses on fitment verification, installation procedure, and expected effects on wheel dynamics and tuning.

Installation procedure: separate the beadlock ring and inner rim, confirm tyre bead seating, align the nylon frame to the alloy ring, and torque with the original hex screws to specified drive practice. Inspect screw thread engagement and hub stud condition before reuse, and perform a runout check plus static balance to identify any assembly eccentricity that could induce vibration.

Engineering notes: combining an alloy beadlock ring with a resilient nylon inner rim increases rim lip stiffness for bead retention while preserving shock absorption and impact resilience at the hub interface. This hybrid construction supports low-pressure, scale tyre applications and reduces peak loading transmitted to suspension components. Validate wheel offset and articulation clearance during chassis setup to prevent contact under full bump and droop cycles.

A practical upgrade for precise trail performance that balances bead retention with impact tolerance while maintaining serviceability and fitment for EXO rear wheel applications.
