The XB913 chassis was completely re-designed for better weight distribution, and is both longer and wider to improve chassis balance and stability and to accommodate the new center diff position. The chassis is CNC-machined from high-quality Swiss 3mm 7075 T6 aluminum, which is strategically machined in low-stress areas and then anodized to make it as light as possible without affecting strength or rigidity.
Non-essential material below the engine, fuel tank, and diffs was removed to allow for the lowest possible center of gravity and appropriate chassis flex. All screw holes on the bottom of the chassis are countersunk, allowing for a very smooth chassis underside with no protruding screw heads. The chassis is a vital component for Multi-Flex setting adjustment, using different screw positions to mount the side guards and radio box plate. Must be used with #351156 XB913 Composite Chassis Side Guards L+R.
Note:
Swiss 7075 T6 is extremely rigid aluminum material and after the hardcoating process in rare cases some small cracks may occur for example, around openings or on edges where tension in the material is highest. Those small cracks are a natural effect and have no negative impact on the performance, reliability, or lifespan of the product and as such are not considered to be a defect.
Due the nature of the aluminum material and the machining process, it is normal that the chassis may be slightly bent in the longitudinal direction.
