This aftermarket package provides a front and rear upper arm pair designed for the HPI Savage 21 platform, supplied for repair or setup adjustments. The arms are formed from Alloy-7075 and the kit contains a titanium tire rod plus the screws and hex wrench needed for fitment.
Installed in place of the factory arms, these Alloy-7075 components interact with suspension geometry and steering linkages, often increasing stiffness at pivot points and changing handling characteristics under load. Inspect your existing mounts and bearing fitment before completing installation.
Installation advice: because screws and a hex wrench are included, most basic chassis installs can be completed without extra small tools. Recheck fastener tightness after initial runs and following any hard impacts to maintain safe operation.
Choose this set to replace worn arms or to trial a firmer arm material in your tuning work; always confirm compatibility on your Savage 21 before extended use.
