The drivelines to the front and rear axles are designed to arrange in a straight-line and this reduces fatigue or stress of the universal shafts and loss of power delivery.
Transmission of the GS02F chassis is designed to look as that of real vehicles. It also provides best performance for every driving situation.
Overdrive system means the front and the rear wheels rotate for different speeds. The GS02F transmission is designed to rotate the front wheels faster than the rear wheels.

Vehicles with overdrive front wheels turn with shorter steering radius compared with non-overdrive vehicles. The overdrive also makes the control easier when the car is driving on rough surfaces.
Increasing of the tire traction allows the vehicle to pass through steep slopes and obstacles without lifting the front of the body upward.
2-speed HI/LO transmission
The 1st gear is for hardcore rock crawling and the 2nd gear is for hill climb or high-speed driving.
torque Twist Reduce transmission
TTR(Torque Twist Reduce) transmission is designed to reduce unnecessary torque so the vehicle will drive with more stability. From the transmission, the front and rear universal shafts rotates clockwise and counterclockwise, and these opposite rotations compensate for rotational forces of action(torque) and reaction(reverse torque).
With the easy motor mount, users can easily replace and install the motor pinion gear for changing the gear ratio.
Dual slipper clutch
Dual slipper pads are designed to hold the spur gear evenly. Therefore the clutch allows more precise settings.
Hardened carbon steel universal joints
The steel joints attached to universal shafts always provide smooth and stable power deliveries.
The kit also provides universal shafts with different lengths, so the user can try other wheel bases or styles.
The GA44 axle is designed for hard core rock crawlers in mind. This high endurance one piece axle is made of high strength materials and will look like real 1:1 scale vehicles’ when it is connected to 4 link suspensions. It is equipped with uniquely designed tilted differential covers and this design will help decrease damages of the differential covers and smoothly climb over the obstacles.
Keeping the scrub radius to a minimum to let your steering servo work at it's full potential and increases the steering efficiency.
High steer knuckle arm system increases the approach angle, so the vehicle can climb over the obstacles more easily than typical trucks.
The GA44 front axle has a caster angle adjustment system which allows users to choose a smoother and shorter turning radius or more straight running stability.

Hardened carbon steel CVA kit
The GA44 axle is using Zero-ackerman steering system with CVA to ensure maximum performance with a short turn radius and smooth motion even on rough off-road terrain.
