The JR-TRX417-10MM is a brass 12mm wheel hex adapter intended for Traxxas TRX-4 HD scale crawlers. It replaces softer plastic hex pieces to provide a more wear-resistant mating surface and help keep wheel clamping consistent during technical crawling.
The 10mm thickness increases the seating contact area, distributing clamping forces and helping to prevent deformation under load when compared to thinner plastic adapters. This product is for RC model chassis and wheels.
Fitment checklist: confirm the wheel's 12mm hex socket and axle hex dimensions, clean mating faces, and torque wheel fasteners to the TRX-4 HD recommended values. No additional parts are included unless noted by the seller.
Compatible with Traxxas TRX-4 HD models that use a 12mm wheel hex interface.
