Gmade R1 Front Knuckle Arm Aluminium GM021 Upgrade for Rock Buggy by GPM  [GM021]

Front knuckle arm suited to Gmade R1

This aluminium front knuckle arm is a scale replacement part for the Gmade R1 1/10 Rock Buggy platform, intended to restore or increase steering link stiffness and front-end behaviour. The arm swaps in for the standard steering knuckle and emphasises mechanical resilience and predictable steering rather than visual modification.

Intended fitment is for the 1/10 R1 Rock Buggy family referenced in the title; fitters should confirm wheel hex clearance, kingpin spacing and suspension geometry before final assembly. Installation generally uses the vehicle's original fasteners and steering components, and alignment should be checked after fitting to verify toe and camber settings.

When tuning, aluminium knuckle arms can reduce flex versus softer parts, helping to keep steering input consistent on rough tracks and while adjusting shocks and suspension settings. Use them within an overall front-end setup strategy, balancing stiffness with shock tuning to avoid overloading neighboring components.

This aluminium knuckle arm is a direct replacement for hobbyists seeking a firmer steering assembly on Gmade R1 1/10 rock buggies; inspect fit and steering geometry after installation to retain the preferred handling balance.
