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

Front knuckle arm for Gmade R1

This aluminium front knuckle arm is an RC-scale replacement part for the Gmade R1 1/10 Rock Buggy platform, intended to restore or improve steering link rigidity and front-end behaviour. The arm replaces the stock steering knuckle and is focused on mechanical durability and predictable steering response rather than cosmetic change.

Fitment is intended for the 1/10 R1 Rock Buggy family designated in the product title; installers should verify fit against existing wheel hexes, kingpin spacing, and suspension geometry before final assembly. Typical installation uses the vehicle's standard fasteners and steering hardware, and alignment should be checked after installation to confirm toe and camber settings.

In tuning use, aluminium knuckle arms can reduce flex under load compared with softer materials, which helps maintain consistent steering input during rough-terrain runs and when adjusting shock and suspension settings. Use them as part of an overall front-end setup process, balancing stiffness with shock tuning to avoid transferring excessive stress to adjacent components.

This knuckle arm is a direct aluminium replacement intended for hobbyists who need a stiffer steering assembly on Gmade R1 1/10 rock buggies; evaluate installation fit and steering geometry after fitting to maintain desired handling balance.
