Serpent 4X chassis magnesium stiffener by Arrowmax AM-900007  [AM-900007]

Chassis stiffener for Serpent 4X

This Arrowmax AM-900007 accessory is an RC-scale chassis stiffener designed for the Serpent 4X platform and Project 4X series. The part provides localized increases in torsional rigidity through an Arrowspace magnesium construction, intended to influence chassis balance and handling during setup and track tuning.

Engineered as a hop-up piece, the stiffener integrates with the chassis mounting layout of Project 4X models without altering core design geometry. Its primary role is to offer a predictable change in flex distribution so builders can tune suspension and roll behaviour without modifying other major components.

Installation notes: this component installs to existing chassis attachment points and is intended to replace or supplement factory braces depending on the chosen setup. When fitting, verify alignment with factory holes and check clearance for drivetrain and suspension components to maintain intended geometry.

As a focused chassis upgrade, this magnesium stiffener is useful for drivers and tuners who need a stable, repeatable change in chassis rigidity on Serpent 4X platforms.
