Rear Shocks
The FireFox 620 is shipped with the rear shocks not attached. It is
necessary to install the shocks in their appropriate positions before
attempting to operate the go-kart. Locate the rear shocks from the
loose parts. Remove the shipping bar from each side of the kart. IM-
PORTANT: The kart frame needs to be properly supported before re-
moving the shipping bars and attempting to install the shocks. Slide
the shock into one of the top housings located on the go-kart frame,
ensuring that the coils are closest to the top housing. Align the pre-
drilled holes in the bracket with the openings in the shock mount.
Slide the bolt through the holes and place the nut on the end of the
bolt and tighten. Repeat this process for the shocks on both sides of
the kart. Do NOT attempt to operate the FireFox 620 without install-
ing both rear shocks in their correct operating positions.
Rear Wheels
Rear Tire Size - 18 x 9.5-8
The rear of the kart needs to be raised in order to install the rear tires.
Be careful not to damage any kart components while raising the rear
of the kart. Remove the nut from the tire hub before attempting to
place the tire on. In order to ensure that the tires are assembled
correctly, place the tire on the hub so that the valve stem faces
outward and the directional arrow rotates towards the front of the go-
kart. To slide the tire on, align the hole in the rim of the tire with the
hole in the rear wheel hubs. Place the nut on the stud and tighten
9
using the provided tools. Repeat this process for the rear tires on
both sides of the kart.
IMPORTANT: The air pressure in the rear tires should register
between 18-20 psi.
NOTE: The rear tires for the FireFox 620 are directional tires.
While assembling the go-kart, please ensure that the valve stems are
facing outward and the directional arrow on the sidewall of the tire
rotates towards the front of the kart.
Front Spindles / Tie Rods
Front Tire Size - 19 x 7-8
In order to install the front tires, you will need to raise the front end
of the go-kart. Be careful not to damage any kart components while
raising the front end. Locate the drivers side tire. NOTE: The
spindle is already attached to the tire and needs to be attached to the
go-kart frame. The drivers side tire will have the directional facing
forward and the valve stem facing out while viewed from the drivers
side of the kart. Remove the nut and bolt from the spindle. Align
the pre-drilled holes in the spindle with the pre-drilled holes in the A-
arm housing. The spindle should slide inside the housing. Slide the
bolts down through all pre-drilled holes and place the nut on the bolt.
Torque the bolt according to specifications. Remove the cotter
10
pin and castle nut from the tie rod on the drivers side. Slide the tie
rod end down through the top of the pre-drilled hole in the spindle.
Place the castle nut on the tie rod end and tighten. Slide the cotter pin
through the opening in the tie rod end and bend each end of the pin in
opposite ninety degree directions. Repeat this process for both front
spindles and tie rods.
IMPORTANT: The air pressure in the front tires should register
between 12-14 psi.
11
Steering Wheel
The steering wheel needs to be moved from the shipping position to
the operating position before attempting to operate the go-kart. Do
NOT attempt to operate this go-kart without moving the steering
wheel into the proper operating position.
1. Locate the steering wheel in front of the Driver’s seat. Remove
the four nuts and bolts holding the mounting plates together.
2. Place the plates in their appropriate position around the frame
of the kart directly in front of the Driver’s seat. The position of
the steering wheel should offer the driver the best possible control
of the kart. Tighten the bolts using the tools provided.
WARNING: Do NOT operate this go-kart without placing the steer-
ing wheel in the appropriate operating position. The operating
position should provide the driver the best possible control of the
vehicle during operation.
