shock shaft and bottom of the shock. Doing so will reduce the life of the shock
and cause a shock to leak oil. Be sure to clean the shocks regularly with a clean
and dry soft bristle brush and/or rag.
CAUTION: NEVER USE SPRAY CLEANERS TO CLEAN YOUR SHOCKS, DOING SO CAN
CAUSE DAMAGE TO THE SEALS, CAUSING THEM TO LEAK MORE AND REDUCE THE
LIEF AND PERFORMANCE OF YOUR SHOCKS.
Signs to look out for in determining if your shock needs to be maintained or
rebuilt.
• Oil around the shaft means the oil leaked from inside and needs to be
replaced.
• Persistent oil around the shock shaft or lower portion of the shock typically
points to damaged O-rings which will need replacing. See your local hobby
dealer for replacement parts.
Refilling your shocks:
1. Remove shock from vehicle, remove spring and top cap. Remove the bleed
screw from the cap.
2. With shock shaft extended, add oil to top of body (use only 100% silicone
fluid) and reinstall the shock cap. Be sure the o-ring stays “seated” and
does not squeeze out.
3. Slowly compress the shock shaft 100% of travel using a towel or paper
napkin to clean up overflowed oil, then reinstall the bleed screw. Do not
over-tighten.
4. Check for free motion of shock. If the shock feels like it gets stiffer at the
end of compression, there is too much oil or air. Compress the shaft and
remove the bleed screw slowly to allow excess air/oil to come out, then
reinstall the screw.
5. It is normal for the shock to rebound (with the spring removed) after full
compression and release.
Replacing the O-rings:
• Disassemble shock and remove shock end and shaft from the body.
• Carefully remove lower cap by unscrewing from the shock body.
• Remove the O-ring and spacer and replace with genuine replacement parts.
• Re-assemble the shock following the refilling instructions above.
Tires and Wheels
Inspect the tires to ensure they have adequate tread and they are properly
glued to the wheels. The tires on your vehicle come pre-glued from the factory;
however after running your vehicle it is possible for the glue to come loose in
some areas.
