TAMIYA CR-01 One Piece Rear Hub by 3Racing CR01-19/LB  [CR01-19/LB]

Product overview

The TAMIYA CR-01 One Piece Rear Hub by 3Racing CR01-19/LB is an RC-scale replacement/hop-up part designed for the CR-01 chassis. This one-piece rear hub is intended as a direct swap for the stock rear hub to support rear axle maintenance, repairs, or progressive tuning of drivetrain geometry on scale crawlers and trail trucks. The write-up below focuses on fitment, typical installation steps, and its role in setup adjustments rather than performance claims.

Compatibility is limited to CR-01 based models where the original rear hub uses the same mounting and axle arrangement. Before installation, verify that shaft diameters, set-screw positions, and hex fits match your vehicle's rear axle components. The part is delivered as a single unit, simplifying reassembly when replacing worn or damaged rear hub components.

Installation notes: removal of the rear wheel and hub assembly is required, followed by extraction of the existing hub from the axle. Check the axle and mating surfaces for wear or burrs, confirm alignment of the hub hex and set screws, and torque fasteners to the values recommended by the CR-01 chassis documentation. Use compatible hex screws and thread locker where appropriate for sustained trail use.

This hub serves as a straightforward replacement or hop-up for CR-01 based scale RC models where a one-piece rear hub is desired for simplified maintenance and consistent mounting; inspect fitment before final assembly and follow chassis torque guidance.
