Serpent 4X Project 4X Magnesium Stiffener Upgrade - AM-900007 by Arrowmax  [AM-900007]

Chassis brace aimed at Serpent 4X handling

The Arrowmax AM-900007 is a magnesium chassis stiffener developed for the Serpent 4X platform and Project 4X lineup. It provides targeted gains in torsional stiffness using a lightweight Arrowspace magnesium design to influence balance and handling as you tune the car for different track surfaces.

Designed as an aftermarket hop-up, the stiffener lines up with Project 4X chassis mounts so core geometry stays intact. Its role is to deliver consistent changes in flex so drivers can refine suspension and roll characteristics without swapping major components.

Installation notes: mount the component to existing chassis points and decide whether it will replace or supplement factory braces based on handling goals. Check hole alignment and ensure adequate clearance for drivetrain and suspension parts before finalising installation.

This magnesium stiffener is a practical tuning part for racers and hobbyists who need predictable chassis stiffness changes on Serpent 4X cars.
