Precision Control - Tamiya 51742 TRF421 D Parts Suspension Arms  [51742]

Refine TRF421 handling with genuine Tamiya arms

The Tamiya 51742 TRF421 D Parts suspension arms are built to preserve the chassis balance of your TRF421. They serve as direct replacements to restore proper steering response and stability during lap sessions.

Compatibility notes

Designed specifically for TRF421 layout, these arms align with the chassis mounting points and kinematics. Using the correct arms helps keep camber and toe behaviour predictable across set-ups.

Fitting tips and upkeep

When installing, verify that pivots rotate freely and that hardware is torqued evenly. Clean and inspect the contact areas regularly to prevent grit-related wear and sudden failures.
