Tamiya CW-01 Front Knuckle Arm LB021 Aluminium Upgrade by GPM  [LB021]

Stiffer front knuckle for CW-01 builds

The GPM LB021 aluminium front knuckle arm is produced as a direct aftermarket replacement for Tamiya CW-01 (Lunch Box) scale RC cars. Sold as one pair, the aluminium arms replace stock plastic knuckles to cut flex and provide a more solid steering mount.

Functionally the aluminium knuckle reduces compliance in the steering system for sharper inputs and gives a longer lasting mounting face for kingpins and pivot hardware. This item is aimed at hobbyists for tuning and routine maintenance only.

Fitment is simple for those comfortable with basic chassis work. Remove the original knuckles, move over any bearings or pins needed, fit the aluminium pieces and then confirm steering centring and suspension geometry. Always check for rubbing or interference with tyres and adjacent suspension parts.

A sensible metal replacement for CW-01 owners seeking less steering deflection and improved pivot longevity in tuning focused builds.
