This item is an RC-scale left rear hub crafted for the Yokomo R12 chassis. By enlarging the left-side hub thickness around the rear shaft, it helps redistribute load between the left and right wheels to promote more uniform traction across the rear axle.
The hub profile is engineered to improve circumferential balance, which lessens irregular wheel wobble and reduces drivetrain losses that may appear at higher speeds. Those improvements can lower stress on related drivetrain parts and contribute to steadier wear patterns when used as part of a well-maintained setup.
Fitment is simple for a standard R12 rear: remove the original left hub, install the R12-24HLC, and confirm that bearings and wheel centring are correct. You will not need specialty tools beyond typical hex drivers and setup gauges, but always recheck fastener torque and clearances after fitting.
Setup note: use this hub alongside tyre choice and suspension adjustments to manage traction and component stress. It is intended to assist overall balance and longevity rather than act as a lone performance fix.
