The rear axle utilizes the Option B Style Brass Portal Cover (PSH00136) which is a larger piece of brass. This item also comes with its own hardware. The reason I used this on the rear is to offset all the weight that the front has. This will keep all four tires on the ground on descents.
The bottom of the skid plate and axles are protected from abuse using the Skid Plate Protector Set (PSH00120).
Moving on to the chassis, I used the Aluminum Servo Mount Style B (PSH00129 – Black). This aluminum mount runs from the servo to the front of the chassis. The mount extends to the front of the chassis and allows you to mount a servo just behind the bumper mount. This will be helpful to mount something like a servo winch to pull all the extra weight around.
Hopefully you can take some inspiration from our TRX-4 – we’re excited to see how you use Prostar Accessories in your own builds! Have fun building and tiny-truck on!
