XRAY have introduced a new 2.5mm aluminum chassis for the XB4’20. This unique chassis features shorter and longer wheelbase integrated in one chassis. There are two different mounting positions for center and rear diff assembly that allows to choose between a shorter and longer chassis alternative. The shorter chassis setting makes the car to rotate better in corners and is recommended for high traction tracks. The longer chassis setting makes the car more stable and is recommended for low traction tracks or bumpy Astro tracks. The thicker and specially milled-out chassis was redesigned for XB4’20 to increase cornering speed and overall stability. CNC machined chassis made from 2.5mm high-quality Swiss 7075 T6 aluminum, it is strategically machined to make it as light as possible without affecting strength or rigidity and to achieve the desired flex characteristics and comes black coated for wear.
