Rebuilding/Refilling the Shocks
Step 1
After removing the shock, push up on
the lower spring cup and remove it from
the shaft. Remove the spring and preload
spacers.
Step 3
Remove the top E-clip from the shock
shaft. Remove the shock piston.
Remove second E-clip. Remove the old
cartridge.
Put a drop of oil on the shock
shaft before installing a new shock
cartridge.
Step 5
If you plan on completely changing
the shock fluid (suggested), dump
out the old fluid from the shock body.
carefully fill the shock body with fluid
to the bottom of the threads inside the
shock body.
Your Mini-Rock crawler comes with
100wt shock fluid from the factory.
Step 7
Turn the shock over and use a #0 Phillips
screwdriver to remove the small bleed
screw at the top of the shock. Slowly
push the shock shaft up until it stops.
Excess fluid should flow out of the bleed
hole. Slowly pull the shock shaft halfway
back and replace the bleed screw. Use
pliers to tighten the cartridge, being
careful not to strip the plastic lobes on
the cartridge.

remove the black shock cartridge/
shaft assembly from the shock body by
turning it counterclockwise.
If you only wish to change or fill the
shock fluid, skip to step 5.
Step 4

shock piston onto the shock shaft
against the E-clip. Reinstall the top
E-clip.

test the shock action for smoothness
and leaks. Retighten the bleed screw
or cartridge if either leaks. Remount
the shock on your truck.
Cleaning
Performance can be hindered if dirt gets in any of the moving suspension
parts. Use compressed air, a soft paintbrush, or toothbrush to remove dust
or dirt. Avoid using solvents or chemicals as they can actually wash dirt into
the bearings or moving parts as well as cause damage to the electronics.
