Baja 5B Gas SBK Kit (No Engine)

We have heard you ! The one and only original Baja 5B is back and ready for you to build from the ground up!

When the Baja 5B buggy was first introduced, large scale RC was very expensive and quite difficult for the average RC hobbyist to experience. Using highly durable parts and innovative design features, HPI brought large scale off-road to new enthusiasts and ushered in a new bigger era of RC!

Now YOU can build and own the legend. Experience the trhill and excitement of building a car wich ends up being over 80 cm long and weighing nearly 10kg!

Just install your own engine and electronics as you build the Baja 5B and you’ll be ready for any adventure that comes your way.

Racing chassis design & layout

The narrow channel chassis made from rigid 4mm 6061 aircraft aluminium and gives the Baja 5B a classic desert racing buggy look and extreme stiffness and durability. The U-shapped chassis is protected at the rear with a tick plastic skid plate for extra protection to the motor and drivetrain.

The tube roll cage is made of high impact nylon and topped with a real aluminium roof to carry on the classic looks. The roll cage is fully functional and protects the motor and internals from crash damage. The roll cage, radio box, body panels, wing, undertray and gear case are all mounted with fast access clips for easy maintenance.

Add your engine & electronics

Building an HPI SBK (Self Build Kit) not only gives you the joy of assembling your own custom vehicle. You’ll also be able to install an engine and your own electronics package as you go!

3 Piece beadlok wheels & off road racing tires

Specially constructed high-impact nylon 3 pieces bead lock wheels are included, featuring inset heavy-duty metal hex hub insert for massively increased wheel durability. 20 screws securely hod the tire in place, no glue is used wich makes changing the tires quick and easy and the wheels can be used again with brand new tires.

To allow the Baja 5B to go anywhere, Dirt Buster off road tires are included that are ideally suited for off road conditions.

The Baja 5B SBK includes these upgrades

#86618 front & rear sway bars, #104966 super heavy duty drive shaft, #104781 rear hub carrier, #105612 heavy duty front hex hub 24mm

High capacity fuel tank

The massive 700cc fuel tank is big enough to allow a 23-26cc size engine to run up to 30 min. at top speed. With the tank located centrally in the chassis, there is no change in handling as the fuel is used up. All required fuel and expansion lines are included in the Baja 5B SBK. Note: the fuel tank should NOT be refiled while the engine is running.

Rock solid reliable drivetrain

The legendary HPI Baja 5B Viscous Torque Control differential delivers the power to the rear wheels with smoothness and precision, starting with the unique composite spur gear with internal damping. The differential can be easily tuned by using differential oils of various viscosities. The metal alloy diff case is finned for extra heat dissipation and to keep the internal gears firmly in place. The HD 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 huge power, big-air jumps and huge top speeds!
