can help with erratic
steering. They provide
a mechanical limit to
the steering throw and
can make the car
easier to drive. They
are recommended in
addition to limiting steering on your
radio to match. Washers (TKR1221) can
also be added for further control.

Note: It is nessesary to slightly loosen both screws holding
the A block in place before attaching the front clip to the
chassis. This is due to the fact that the A block is now
keyed into the front of the chassis. This feature helps
secure the front clip and improves durability.

Shock Filling Instructions
For both front and rear shocks
Step 1. Start by inserting the four larger o-rings into the emulsion caps and set
aside. Next install the small o-rings onto the small emulsion screws.
Step 2. Fill shock with oil all the way to the top and pump the shock shaft up and down 3-5 times.
Step 3. Screw on the cap all the way tight (shock tool TKR1115 is helpful for holding the shock body).
Be careful to not cross-thread the caps. Start by turning in the oposite direction before tightening.
Step 4. With the shock at about a 45° angle, push and hold the shock shaft to the top of the stroke and
insert the prepared emulsion screw/seal. Oil should leak out during this process. If it does not, add more oil.
Tighten the screw until snug (do not over-tighten). Wipe o excess oil before moving on to step 5.
Step 5. Pump the shock shaft up and down about 20 times vigorously. This emulsifies the oil.
Step 6. With the shock shaft fully extended, remove the emulsion screw from the cap to do the final bleed.
Step 7. With the shock at about a 45° angle, push and hold the shock shaft to the top and insert the
prepared emulsion screw/seal again. Oil will leak out during this process. Finish by tightening the screw
until snug (do not over-tighten).
We've found it's easiest to complete steps 1 & 2 on each shock before moving on to step 3.
By the time you've finished step 2 on the last shock, the first one will be ready for step 3.
Note: Kit shock oil is suited for ~75°F (~24°C). If ambient temperature changes more than ~10°F (~5°C), adjust oil to suit.

IMPORTANT RADIO SETUP TIPS, MUST READ:
The Tekno RC ET410.2 is highly tunable, but can be very
aggressive depending on track conditions and tires used.
To help with this, we recommend that you are well informed
about setting up your Steering EPA, Servo Speed, Dual Rate,
and Exponential Curves.
PLEASE READ PAGE 27 FOR MORE DETAILS.
Steering servo (not included)
TKR6586
TKR1403
Note: We recommend using
a full size servo with at least
200 oz/in torque and metal
gears. Running less than our
recommended rating will
increase the chance of
premature servo failure.
