The legendary HPI Baja 5B Viscous Torque Control differential delivers the power to the rear wheels with smoothness and precision. The differential can be easily tuned by using differential oils of various thicknesses. The metal alloy diff case is finned for extra heat dissipation and to keep the internal gears firmly in place. The diff outdrives or cups are machined from hardened metal for reliable performance in all conditions. The internal gears are also made from hardened metal to handle 8S power, big-air jumps and huge top speeds!

The HPI Baja 5B SBK is built for long-lasting fun, thanks to its massive 700cc fuel tank. This high-capacity tank allows for extended run times, while its central location ensures consistent handling characteristics, even as fuel levels decrease.
