HPI Racing Savage XL FLUX Aluminum Front/Rear Upper Arm 2pcs by GPM SAVF1054  [SAVF1054]

Aluminum front/rear upper arm for Savage platform

This is an RC-scale replacement upper arm set designed for HPI Savage platforms, sold as a 2pcs set. The parts are intended to support the front and rear gearbox assemblies and the knuckle/steering arm areas, providing a direct metal alternative to stock plastic components.

Manufactured from 6061 T6 aluminum, the arms increase structural stiffness at suspension pivot points while keeping weight controlled for model-scale handling. Delrin collars are pressed into the mounting bores to reduce play at the hinge pin interfaces and to stabilize the mating surfaces for smoother operation.

Installation replaces the stock front and rear upper arms, using existing hinge pins and hardware on the chassis. Basic fit checks are advised after installation to confirm pin alignment and free suspension travel. These parts are intended as bolt-on upgrades for model maintenance, repair, or tuning to alter flex characteristics and durability.

Use these aluminum arms when you want a metal replacement for the stock upper arms on Savage platforms, check hinge pin fit and suspension geometry during installation, and inspect Delrin collar seats periodically for wear.
