The GPM SAV1054S set provides alloy front and rear adjustable upper arms engineered to reinforce suspension strength on HPI Savage models. These parts are intended to replace weaker factory components and include steel tie rods to let you set suspension geometry with repeatable results. The design focuses on durable fitment and consistent handling in demanding RC use.
Install with attention to symmetric geometry across left and right sides, and verify tie rod lengths before final tightening. Periodic checks of fastener torque after initial runs will help ensure long term performance.
