TAMIYA DT-04 7075-T6 Rear Upper Suspension Arms DT4057 by GPM  [DT4057]

7075-T6 alloy rear upper arm for DT-04

This aftermarket rear upper suspension arm is a scale replacement made for the TAMIYA DT-04 RC FIGHTER NXGEN platform. Constructed from 7075-T6 aluminium to keep mass low while increasing structural stiffness over standard plastic parts. The component is intended for hobby use to improve longevity and deliver more consistent handling when you adjust setup settings.

The package arrives with the arm and all required mounting hardware pre-assembled, allowing a straightforward swap with the stock rear upper suspension arm. Use a medium-strength thread locker on fasteners to keep clamps secure under vibration.

Replace worn factory arms with this aluminium unit to stiffen rear end response; verify pin seating during install and apply medium-strength screw glue or thread locker to secure the screws.
