1 - Build up the left and right steering blocks [66] as shown to the left. Start by threading the 1/4” button head screw
[21] through the steering arm [67] and into the red low profile ball [12].

2 - Then, slide the steering arm assembly into the steering block, lining up the 2 mounting holes. Using the black 2-56
socket head screws [68], fasten the arm to the steering block. DO NOT OVER tighten. You will drive the screw
through the steering block, deforming the part.

1 - Push the Dual aluminum axle [69] into the plastic steering block [66]. Push it all the way
in firmly. Notice you can install the axle inline or trailing. Typically, this is installed trailing for
1/12th road racing. This will slightly slow the steering response as compared to inline.

2 - Take the King pin [70] on the end of the Allen key and slide it through the lower arm pivot
ball [54], & then thread it into the steering block. Thread it in until some resistance is met.
This is the King pin beginning to thread into the top of the steering block after traveling
entirely through the dual axle.

3 - Add the spring [71] to the king pin. The preload on the spring can be adjusted with the
king pin length. When on the king pin, you want the end of the spring flush with the e-clip
groove. Start by adjusting the king pin so you have to slip the e-clip [72] under the spring to
get it in the groove. Just a bit of preload.

4 - Once happy with the preload position, lock the king pin with the 4-40 brass set screw
[73] through the back of the steering block.

1 - Use the large 8-32 screws [77] to mount the front suspension assembly to the chassis.
Push the screw through the chassis and then screw into the lower front suspension arm.

2 - Tighten both screws firmly. Be careful not to strip the head of the screw or the threads in
the arm.

3 - Do both left and right.

4- You can change ride height spacers or use CRC’s 4262 plastic shim kit for fine ride height
adjustments.

1 - Take the upper pivot ball [74] and push it though the steering block and
thread into the upper arm. Thread it in so there are no threads showing.

2 - Take the slotted capture insert [75] and thread it into the steering block. THIS
IS A BIT TRICKY .... as the insert must be fitted at a down angle as shown to the
left. DO NOT try to insert it horizontally into the steering block. It is actually
threaded in at a down angle toward the center of the car.

3 - Tighten this capture insert so that the steering movement is bound and slow.
Yes, we are actually slightly over tightening this piece FOR NOW. With the
steering movement bound from over tightening, move the steering to it’s limits,
back and forth. What we are doing is “breaking in” the upper ball/capture insert.
After a minute or so of break in, loosen the insert just enough so the steering is
free. Not too much or you will induce excessive free play.
