3728A Lower chassis (gray) (166mm long battery compartment) (fits both flat and hump style battery packs)

This product is a genuine Traxxas lower chassis in gray, featuring a 166mm long battery compartment compatible with both flat and hump-style battery packs. Molded from high-strength composite material, it provides durable support while maintaining proper suspension geometry and drivetrain alignment. The reinforced construction resists flex and impact during aggressive driving. It serves as a direct replacement component for compatible Traxxas 1/16-scale models, restoring structural integrity, factory fit, and reliable performance.
