Traxxas 5122X Chassis, T-Maxx®, long wheelbase (extended 30mm) (6061-T6 aluminum, 4.0mm) (blue anodized)

The replacement 4 mm aluminum T-Maxx^® extended-wheelbase chassis is formed from durable 6061-T6 aluminum and then anodized in beautiful blue. Besides forming a rigid backbone for the rest of the truck, the aluminum acts like a heat sink to draw additional heat away from the engine.
