SLASH 4x4 PLATINUM EDITION
Shock Disassembly
The shocks must be removed from the vehicle and disassembled
to change the pistons. Use the shock exploded views included
with the model to aid in the assembly process.
1. Remove the spring and lower spring retainer from the shock.
2. Remove the shock cap (A) and empty the shock body of
shock oil.
3. Use side cutters to grip the shock shaft just above the rod end
(B). Unthread the rod end from the shock shaft.
4. Remove the shock shaft with piston from the shock body out
through the top of the shock body.
5. Use the corner of the tip of a small, bladed screwdriver
to remove the E-clip that secures the piston. Wear eye
protection in case the clip pops off. Tip: work beneath a rag
to catch the clip if it pops off.

Shock Assembly
1. Replace the stock piston with desired optional piston.
2. Slide the E-clip onto the shaft. Squeeze it into place using
needle-nose pliers.
3. Lubricate the threads of the shock shaft and insert the shock
shaft assembly through the shock body until the piston
bottoms out.
4. Grip the shaft close to the threads with needle nose pliers or
side cutters and thread the rod end onto the shock shaft until
the rod end bottoms out.
5. Fill the shock with new silicone shock oil up to the top of the
shock body. Slowly move the piston up and down (always
keeping it submerged in oil) to release the air bubbles. Let
the shock sit for a few minutes to allow any remaining air
bubbles to surface.
6. Slowly thread the upper cap with the installed shock bladder
onto the shock body. The excess oil will bleed out of the small
hole in the shock cap. Tighten the shock cap until snug.
7. Reinstall the spring and lower retainer.
Sway Bar Settings and Adjustments
• Adjust the sway bar links so the sway bars are level (parallel
to the ground) when the truck is on the ground and the
suspension is at rest (normal ride height). This allows equal

sway bar travel in both unloaded and loaded suspension
conditions. Always adjust the left and right sway bar links
equally to prevent suspension tweak.
• The adjustable hollow balls
can be moved closer to or
farther from the sway bar
mount (pivot point) to increase
torsion response and fine
tune the sway bar's response
for different track conditions.
Closer to the pivot point results in a stiffer setup, farther from
the pivot point will result in softer sway bar response.
For smooth surfaces with high traction:
• Adjust linkage placement for stiffer response
(closer to the sway bar mount).
For rough surfaces with low traction:
• Adjust linkage placement for softer response
(farther from the sway bar mount).
To reduce understeer (pushing in corners):
• Adjust front linkage placement for softer response
(farther from the sway bar mount).
• Adjust rear linkage placement for stiffer response
(closer to the sway bar mount).
To reduce oversteer (loose in corners):
• Adjust front linkage placement for stiffer response
(closer to the sway bar mount).
• Adjust rear linkage placement for softer response
(farther from the sway bar mount).
Tuning the Center Differential
The center differential allows the power from the motor to be
transferred to the front and rear differentials independently from
one another. When the rear wheels are under more load than the
front wheels, more power will be transmitted to the front wheels.
This is very beneficial on rough terrain and makes hard acceleration
from low speeds easier to control by keeping the nose down.
The center differential is assembled with 100K differential lube
from the factory. This viscosity will be a good base point for
most conditions. Thinner fluid will transfer power more easily
than thicker fluid. Try thinner fluid on extremely rough and slick
surfaces, and thicker fluid on very smooth and high-bite surfaces.
Traxxas offers silicone differential fluid in a variety of viscosities:
Part #5135: 10K
Part #5136: 30K
Part #5130: 100K
Part #5039: 500K
Follow these steps to remove and refill the differential:
1. Remove the two 4x12 button-head cap screws from the top
of the chassis.
2. Remove the two 4x12 button-head cap screws from the
bottom of the chassis.
3. Pull the rear suspension assembly away from the chassis.
4. Remove the center differential by pulling it away from the
rear gearbox.
5. Remove the four 2.5x10mm screws from the differential case
and carefully pull the diff case halves apart. Work over a towel
to collect any fluid that drips from the differential.
6. Drain the fluid from the differential. You may wish to remove
the spider gears from the differential to make this easier.
