HPI Savage 21 Alloy Front and Rear Lower Arms Upgrade - SAV1055E by GPM  [SAV1055E]

Replacement alloy lower arms compatible with Savage 21

This front and rear lower arm set is offered as a direct replacement for HPI Savage 21 chassis and uses the model number SAV1055E. The parts are supplied with the mounting screws, pins and E-clips cited in the title so they can be fitted to the standard suspension points.

The arms carry out the same duties as the original plastic links: they locate the suspension geometry, transfer loads from the hubs into the chassis and affect roll and steering behaviour. Swapping to alloy will alter stiffness and wear patterns relative to stock plastic, so expect to revise damping or spring choices during tuning.

Fitment advice: attach the arms with the supplied hardware, check pivot clearance and ensure there is no interference with the gearbox or drive shafts, then confirm wheel alignment and ride height before operating the vehicle. This is an aftermarket component for compatible RC kits and chassis only.

If you want a firmer lower-arm option or are replacing degraded plastic arms on a Savage 21, this alloy set with included hardware is a practical choice for maintenance and basic setup changes.
