Precision Upper Arm Pair SAVF1054 for HPI Savage by GPM  [SAVF1054]

Technical overview of the upper arm upgrade

This 2pcs upper arm set is engineered as a durable replacement for stock plastic arms on HPI Savage chassis, serving reinforcement roles at gearbox mounts and knuckle pivot points while maintaining controlled weight for predictable dynamics.

Manufactured from CNC-grade 6061 T6 aluminium, the components improve structural rigidity at suspension pivots. Press-fitted Delrin collars at the hinge bores reduce radial clearance and stabilise the pin interface for improved repeatability under load.

Installation is carried out using the vehicle's existing hinge pins and hardware. It is recommended to verify hinge pin alignment and suspension travel during initial fitting, and to periodically inspect the Delrin seats for wear as part of scheduled maintenance.
