The XRAY 361115 XB4 Aluminum Chassis is built for competitive track use, machined from 2.0mm Swiss 7075 T6 aluminum to cut weight while keeping stiffness where it matters. CNC pockets remove material from low-stress zones to reduce mass without sacrificing strength, and the black-coated surface helps resist wear from routine racing use. This chassis mates with low-profile bumpers to give a clean undertray and improved handling response.
A dependable, lightweight foundation for XB4 racers who want better agility and toughness without adding bulk.
