Step 9 - Body & Side Shock Mount Installation
Locate the Shock & Body mounts (HD-7320), 2 Aluminum
Ball studs, 8 1/4” BH screws, 4 .020 shims, and 2 4-40
lock nuts.
Install a ball stud from the front of the shock mount using
the second hole down from the top. Place two .020” shims
over the threaded shank of both ball studs. Secure them
using a 4-40 lock nut. Repeat for the opposite side. Using
two 1/4” BH screws each, attach the completed shock
mount to the cross brace. Refer to fi gure 10 for proper
placement.
Using the remaining four 1/4” BH screws, attach the body
mounts to the cross brace.

Step 10 - Top Plate Installation
Locate the Center/Offset top plate (HD-7315), four 1/4”
BH screws, three aluminum ball studs, and three 4-40 lock
nuts. From the top of the top plate, insert one ball stud in
the right most forward hole and secure it with a 4-40 lock
nut from the bottom of the plate. Insert two more ball studs
in the right most hole locations securing each with a 4-40
lock nut. Install the fi nished top plate onto the rear pod
using the remaining four 1/4” BH screws. Refer to fi gure 12
as needed.

Step 11 - Shock Assembly and Installation
Assemble the Center shock (TAM-1000R) and the side
shocks (SK-1000R) as per the instructions included
with each shock. Hyperdrive suggests using high quality
silicon shock oils in your shocks. A good starting point on
the shock setup is 40 wt. in the center shock and 30 wt.
in both side shocks. Also start with the softer of the
provided springs. At this time also attach the side shocks
onto the ball ends. Make sure to use the included
Associated Heavy Duty Ball Cups on both ends of the side
shocks to attain proper shock length. The center shock will
require a SHC screw and 4-40 lock nut supplied with the
center shock mount for installation.

Step 12 - Bearing Carrier Installation
Locate the Ride Height Set (PP-2312) and choose the
two adjusters with the holes in the center. Depending on
the Final ride height of your car these may have to be
changed. Note: Always install the same adjuster on each
side of the pod in the same orientation. Failure to do this
will cause the rear axle to bind and possibly destroy your
bearings.
Insert the two adjusters into the Pod sides. Press them in
until they are fl ush with the inside of the Pod sides. Install
a Rear Axle / Right Hub Bearing (1/4” x 3/8” fl anged) into
each of the Ride Height Adjusters (see fi gure 14).

Step 13 - Rear Axle / Differential Assembly
Locate the following for the Diff and Rear Axle assembly:
Rear Axle (RA-0401), Offset Diff Hub (RA-2405R), Left
Side Wheel Hub (RA-2410R), Micro-Washers (RA-0403),
Spur Gear Bearing (RA-0408-NF), Rear Axle and Right
Hub Bearings (RA-0408), Diff Centering Set (RA-0411R),
Diff balls (DB-0901), Diff Rings (DR-1002) and Spur Gear
(SG-0116).
Install the Spur Gear Bearing (1/4” x 3x8” fl angeless) into
the center of the Spur Gear. At this time also install the Diff
Balls into the outer ring of holes in the Spur Gear. Install
two of the Rear Axle / Right Hub Bearings (1/4” x 3/8”
fl anged) into the Diff Hub. Place one of the Diff rings onto
the shoulder of the axle.
Place a small amount of diff lube on each of the diff
balls installed in the spur gear and place the spur gear
assembly onto the axle. Now place the second diff ring
onto the spur gear and slide the Diff Hub down over the
axle making sure the diff ring aligns onto the shoulder of
the hub.
15
Install the Diff Centering cone over the end of the axle and
secure it with the supplied nylon nut. Tighten just enough
to hold the assembly fi rmly together.
Step 14 - Axle Installation
Place three micro washers over the free end of the axle.
Insert through the right bearing carrier. Place one more
micro washer, and two wide axle spacers, and the left
side clamping hub on the free end of the axle and tighten
assembly.

Final Assembly
Finally install your electronics, Motor, Battery, Tires and
Body. The location of your Steering Servo, Electronic
Speed Control and Receiver are entirely up to you. Take
great care when mounting these to the Chassis as their
location effects the balance of the car. Also care should
be taken when drilling, fi ling or sanding on any of the
graphite components of your car as graphite dust is
hazardous to your health. Tires are not included with
this kit because every track and driver will have different
preferences. If you are unsure of which tires to put on your
car, consult your local hobby shop staff and they should be
able to help you get the right combination for the track you
are racing on.
