This kit contains a matched pair of front and rear upper arms intended for the HPI Savage 21 chassis, supplied for replacement or tuning trials. The main arm bodies use Alloy-7075 and the package includes a titanium tie rod along with screws and a hex wrench for installation.
Replacing the factory arms with Alloy-7075 pieces and a titanium tie rod will modify stiffness around the suspension mounts and can influence steering feel and suspension behaviour during setup. Always confirm link and bearing clearances before completing the installation.
Fitting notes: supplied hardware and hex key allow basic on-chassis assembly. Verify proper thread engagement and retorque fasteners after initial running and following any heavy impacts to avoid loosening.
Ideal for replacing fatigued plastic arms or testing a stiffer material in tuning; confirm Savage 21 fitment before extended use.
