These GPM adapters are designed to extend the wheel track of the Axial RR10 Bomber by 21mm, delivering improved lateral stability for demanding rock crawling and technical lines. The 5mm centre hole preserves compatibility with common hub and spacer arrangements.
The adapters employ an o-ring with a spring steel ring on one side and a spring with washers plus a stainless steel screw on the opposite side to ensure secure seating. This layered retention prevents the hex wideners from rotating under high torque or high traction conditions.
