Axial Racing EXO Nylon Rear Rim Frame with Alloy 5-Star Beadlock Rims by GPM EX0503R  [EX0503R]

EXO rear rim frame and beadlock

This is an RC-scale rear rim frame set designed for the Axial EXO platform, supplied by GPM as part number EX0503R. The assembly pairs a molded nylon rim frame with alloy five-star beadlock rims, provided as a 1 pr set to replace or upgrade factory rear wheels on EXO chassis models. The description focuses on fitment, installation checkpoints, and how the part affects wheel setup and tuning.

Installation is straightforward for builders familiar with beadlock wheels: separate the beadlock ring from the wheel, seat the tire bead, align the nylon frame with the alloy ring, and secure with the original hex screws. Inspect existing hex screw threads and wheel studs before reuse, and verify the bead seating and tire balance after assembly to avoid vibration in scale trail runs.

Tuning role: this combination places a stiffer alloy ring on a resilient nylon frame to balance durability and shock absorption. Use the assembly to maintain bead security on low-pressure, scale-style tires and to preserve wheel alignment under crawling and trail loads. For chassis setup, check wheel offset and clearance with suspension articulation and bump travel to prevent contact with suspension components.

For builders replacing worn EXO rear wheels or swapping to a mixed nylon-alloy construction, this set provides a direct-fit option that keeps beadlock functionality and preserves tire seating for scale trail use.
