The HPI Baja 5B SBK is a 1/5 scale, 2WD gas-powered desert buggy sold as a self-build kit. It includes a clear polycarbonate body ready for your own paint scheme. The engine and electronics are not included. You install your own 23-32cc 2-stroke engine and radio gear as you build.
The chassis is a 4mm thick 6061 T6 aluminum monocoque with gunmetal anodizing. The suspension is molded composite with long-travel, adjustable heavy-duty shocks and an aluminum rear shock tower. The wheels are 3-piece beadlock wheels in high impact nylon with metal insert hubs. The drivetrain has all-metal gears, a composite spur gear with internal damping, and an oil-filled viscous torque differential. Steering uses a dual bellcrank rack and a cam-type servo saver.
The roll cage is high impact nylon with an aluminum roof. The roll cage, radio box, body panels, wing, undertray and gear case mount with fast access clips for maintenance. This kit includes front and rear sway bars, 9mm super heavy duty drive shafts with rubber boots, one-piece rear hub carriers and 24mm heavy duty front hex hubs. The rear hub carriers allow toe-in adjustments of 0 to 4 degrees. With a suitable engine, run times of up to 30 minutes are possible.
