How to change your shock oil
The standard shock oil in your kit’s shocks is
intended to provide forgiving, fun handling and
allow the shocks to soak-up any punishment you
choose to give them.
Changing the oil within the shock absorber
can significantly change the handling and
performance of the car.
Hold the shock
body carefully in
a pair of pliers,
place an allen

Weight Characteristic
Thinner Softer damping
(lower CST) More traction
Quicker chassis weight transfer
Car reacts more quickly
More chassis roll
More chance of 'bottoming out'
Heavier Stiffer damping
(higher CST) Slower chassis weight transfer
Car slower to react
Less chassis roll
Less chance of 'bottoming out'
Tools Required
2mm Hex Driver 5.5 & 7mm Nut Driver or Cross Wrench
Ev er y 50 r uns or so it ma y be
necessary to change the shock oil because over time it will
become thinner meaning kit handling could be affected. You
can also use this as an opportunity to upgrade the springs
or shock oil.
Front Rear
Remove lower shock bolt with 2mm hex driver.
Remove upper shock nut with 5.5 nut driver or cross-
wrench. Remove shock absorber. Remove lower shock bolt with 2mm hex driver.
Remove upper shock nut with 5.5 nut driver or cross-
wrench. Remove shock absorber.
Springs
Your kit’s standard springs are quite soft to give
the best compromise between handling and performance.
Swapping the springs for either softer or stiffer springs can alter
the handling characteristic of the car significantly. To change the
springs remove the lower spring support and slide the spring
over the shock body.
To find out what spring options there are for your kit please visit
ARRMA-RC.com or speak to your local distributor.
