GPM DT3057 Technical Rear Upper Arm for Tamiya DT-03

The GPM DT3057 is a CNC minded aluminium rear upper arm engineered for the Tamiya DT-03 chassis to reduce compliance in the rear suspension. Material choice and machining tolerances improve pivot repeatability and resistance to impact fatigue compared with stock plastic arms. The component supports consistent suspension kinematics under competitive loading and extended use.

Technical Highlights

  • CNC oriented aluminium construction for improved wear resistance
  • Precision contours to maintain predictable suspension articulation
  • Formed to match Tamiya DT-03 mounting geometry for direct replacement
  • Appropriate for performance oriented hobbyists seeking durable upgrades

Packing includes

  • 1 Pair of Aluminum Rear Upper Arms

Compatible Models

  • Tamiya DT-03

What mounting hardware is required?

The DT3057 installs using the standard DT-03 mounting points and commonly supplied screws. Users often reuse factory hardware or upgrade to steel fasteners for added security.

How does aluminium affect dynamic behaviour?

Aluminium reduces part compliance, which yields more consistent wheel motion under load and can improve steering feedback and mid corner stability when combined with appropriate shock and spring setup.

Is finish treatment required to prevent corrosion?

Anodised or coated aluminium resists surface wear and corrosion; regular cleaning after exposure to grit or moisture helps prolong the finish and fitment tolerance.
