Suspension Down Stop Screw Installation
Covers Part #5554
In order to install the down stop screws into the suspension arms, holes must be carefully drilled into the arms with the
included 2.5mm drill bit. Drilling of the adjustment holes is performed with the arms attached to the Jato. Take your
time and be very careful while drilling. Always wear safety glasses. Do not allow the drill bit to move side to side, or the
hole will become enlarged. When drilling the holes take care not to damage any other parts. You are modifying these
parts at your own risk. Traxxas is not responsible for any parts damaged during the drilling procedure.

Locate the dimples (drilling locations) on the front arms. For correct
hole alignment, the drill must be held perpendicular to hole surface.
To make this easier, first place your Jato on a flat table. Press the front
of the Jato down, compressing the front suspension until the bottom
of the chassis stops against the table. With the stock front wheels and
tires installed, this procedure positions the hole locations so that the
drill can be held perpendicular to the table surface for drilling (easier
visual alignment). Insert the tip of the drill bit into the dimple. Hold

front(1) and then tilt the drill back to match the kick up angle of the chassis (2). Starting slowly at first, carefully drill the hole all the way
through the arm. Be very careful not to allow the drill to move side to side, enlarging the hole.

3. Thread a 3x8 set screw into each hole from the top of each suspension arm.
4. To adjust the down travel, start with the bottom of each set screw flush with the
bottom of each hole location. Prop the vehicle up off of the flat surface so the
wheels can be removed without affecting the suspension, remove the wheels.
As the down travel is adjusted to the desired amount, measure the distance
from the lower outer edge of each suspension arm to the surface (A).
Set the left and right arms equally.

Down stop set-up tips: Large changes to down travel can be made by changing the lower shock
location on the suspension arm. This also changes the damping affect of the shocks. Once the
desired shock location is found, use the down stop screws to fine-tune the down travel of the arms.
• For smooth surfaces, limit the down travel (Note: extreme•limitation of down travel can cause
twitchy and erratic handling).
• For rough surfaces, allow more down travel
