Changing the shock oil (the oil inside the shocks) will change the damping characteristics of the shocks. In general, using heavier shock
oil may not allow the X-Crawler ARR to react as quickly to suspension changes and using lighter shock oil may make the X-Crawler
ARR bounce a bit without absorbing bumps in the terrain.
reCoMMended initial SettinGS
We recommend using the stock shock oil that the shocks are already filled with.

The shocks are filled with 20Wt silicone shock oil.
IMPORTANT: Use 100% silicone shock oil. do not use motor oil.
The shock spring tension can be adjusted to fine-tune the chassis ride height and the damping quality of the suspension system.
Threading each adjusting ring down increases spring tension and the chassis's ride height, and will stiffen the overall damping
characteristics of the suspension. Threading each adjustment ring up decreases spring tension and makes the damping characteristics
of the suspension softer.
reCoMMended initial SettinGS
We recommend initially leaving each adjustment ring in its factory location.
l
The wheelbase can be adjusted to suit the type of course or terrain you're driving on. The longer the wheelbase, the more stable the
X-Crawler ARR will be, but the turning radius will be wider. In some cases you may want to shorten the wheelbase if you need a tighter
turning radius because the course you're driving on is tighter.
reCoMMended initial SettinGS
We recommend initially leaving the wheelbase set at the factory length.

1 - Remove the shock from the X-Crawler ARR, then carefully unscrew the shock cap.
2 - Slowly pull the shock piston down completely, then empty the shock oil from the shock
and wipe away any excess.
3 - Fill the shock body with new shock oil until the oil level is just below the top of the
shock body, then gently pump the shock piston up and down to dissapate any air
bubbles from the shock oil. Top off the shock oil level if necessary, before reinstalling
the shock cap.

1 - Increase or decrease spring tension by threading the adjustment ring up or down
each shock body.

1 - Increase or decrease the wheelbase by moving both outer and inner link rods in or
out one hole in the chassis side plates. Moving the link rods toward the centre of the
chassis side plates will shorten the wheelbase and moving the link rods toward the
outside of the chassis side plates will lengthen the wheelbase.
IMPORTANT: If you change the wheelbase, you will need to readjust the lower
shock holders so that the ride height doesn't change.
