Spur Gear Guard
Helps prevent the spur gear from slinging debris all over the inside of the car and especially into the air filter. Works for rain and water puddles.

Piston Braking system
Provides more stopping power than you could have ever imagined before with a whole lot less servo power. Also is fully adjustable with 3 types of pistons
solid, O-ring type, spring type.  In turn you can adjust your bias or braking feel to your liking in more ways than ever before.

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.

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. You simply will only need to adjust your end points on your radio..  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 steering knuckle, helps reduce the jacking effect created by your steering knuckle offset. It provides a more direct fell while keeping the cars chassis more level while turning.
