Slash 4x4 C hub upgrade 6061 T6 aluminum XO019 by GPM  [XO019]

6061 T6 C hubs tailored for XO-1 steering

This 2 pcs set of C hubs is an RC-scale replacement machined from 6061 T6 aluminum, with Delrin collars pressed into the bore to restrict lateral play between the hub and knuckle arms. The low-friction collars help the steering geometry remain consistent under load, which is helpful when dialing in steering feel on TRAXXAS Slash 4x4 platforms.

The parts are supplied as a matched pair and sit where the stock plastic C hubs mount; they keep the same mounting points but use metal construction to resist wear. During installation check fitment against the knuckle and steering link positions and confirm there is no interference with existing hardware or bearings.

From a tuning perspective these C hubs are a chassis-level hop-up to reduce slop in the steering train so caster and toe adjustments produce more precise wheel direction. Because metal hubs add stiffness compared with stock plastic, re-check alignment and steering endplay after fitting.

For builders wanting a straightforward metal replacement to cut steering play on compatible Slash 4x4 XO-1 builds, this GPM 2 pcs C hub set offers a direct upgrade; always inspect fit and alignment during assembly.
