Prepainted and pre-cut Monster Truck body.

Premounted oversized tires/wheels heavy duty profile for incredible grip.

Very narrow 3mm 7075T6 aluminum chassis, with machining on the upper face, to make it lighter in strategic locations and to control flex. Kick-up front for proper landings. Angled side to increase cornering clearance, and secure and easy mounting side guards with 5 screws. Countersunk holes. Overall the Monster Truck is designed to keep the weight very central and near to the centerline as possible, to create a great overall balance.


Side guards/battery trays
Durable shaped composite extra large side guards/battery trays that follow the line of the chassis, and mount with 5 screws on each side. Front and sides are high enough to keep the dirt out. The guards/trays create a lot of stability. The batteries are mounted in a longitudinal fashion, keeping the weight very low in the car. The battery trays feature easy-to-use Serpent-marked falcon TM straps to secure the batteries in place. It Fits 2S and 3S batteries.

Motor mount
The motor is placed in the most optimal position in the car, keeping motor forces and transmission parts/alignment in mind. Only one screw is needed to secure the BL motor, in the nicely designed durable machined aluminum motor mount. Space for additional motor cooling is available as needed. The space for the motor allows mounting all popular buggy and monster truck motors.

Composite chassis braces
Allows the chassis to flex which helps improve bump handling. Front and rear.

Front bumper system
The durable composite front bumper system will absorb the worst of head-on crashes and will allow for save nose landings

Rear bumper
The rear bumper section is a very durable unit, easy to disassemble, and fits well with the rear of the body, to absorb the worst of back-end crashes.


Front Suspension
Very long and durable composite lower wishbones, combined with upper spring-steel track rods. 2 lower shock-mount positions. Downstops can be used as needed.

Front steering/servo saver / angled
Innovative angled front steering assembly to reduce the angle of difference between the total caster and steering plane. Therefore you will have less bump steer and a truer steering Ackerman through the entire range of suspension.

An adjustable spring-loaded servo-saver system with interchangeable Ackermann plates. With the design of the steering bell cranks when changing the Ackerman you will not need to adjust your steering tie rods. Very easy to access and set up.

The Inboard Bell crank keeps the lever and linkage inside the car. It will aid in the prevention of damage to the steering system. Zero scrub radiuses on the steering knuckle help reduce the jacking effect created by your steering knuckle offset. It provides a more direct feel while keeping the car's chassis more level while turning.

The front roll center can be changed quickly by moving the steering knuckle shims to their appropriate locations.

Topped off with a strong composite top plate.

Front steering-block/c-hubs
Very durable front steeringblock/c-hub assembly.


Long and lightweight spring steel units with pressed-in steel pins, laser-engraved. Same length front and rear.

Wheel-axles / wheel-nut
Serpent spring steel wheel-axles with grey anodized aluminum wheel hex-adaptors and aluminum wheel-nuts to keep the massive monster truck wheels/tires on the track.

Captured universal joints
Guarantees you will finish a race without losing a pin or set screw. All parts, axles and drive train components have capture pins

Front shock tower
Light, strong, and durable machined 4mm aluminum units with 3 positions for shock angle and 4 positions for the camber link.

Shock-set front and rear
24mm big bore shocks, with hard anodized precision, threaded shock bodies. Chromed shock-shafts for supersmooth shock action. The larger o rings provide less overall pressure and a better seal without dragging on the shock shaft.


Suspension brackets
The hinge pins are in durable composite suspension brackets secured with c-clips.

Receiver box/servo mount/speedo mount
Composite one-piece radio box to securely mount the servo, speedo, and receiver. For optimum balance, the light receiver fits the top case easily, with a small opening to allow the cable to protrude. The speedo seats very low on a plate just above the chassis, so short cables can be used for the motor. The servo is mounted in a vertical fashion.

Central diff
Optimized central gear-diff with 52T super-hard spur-gear. Very small, compact design to reduce rotating mass to the max.

Transmission shafts
Durable but light and thin Serpent spring steel, laser engraved shafts.

Front and rear diff
Optimized gear-diff with superhard diff-gears. Very small, compact design to reduce rotating mass to the max same version front and rear. Diff coupler in spring steel seated in large bearings for durability.
