Shock Setup
Note: The information below will on any ATV
suspension that has the correct extended shock length with the
correct wheel travel. Do not ride your ATV till it has been setup
correctly!!!
Please
take the time to read through this shock setup sheet and follow
instructions to ensure the best possible performance.
1.
Carefully install your suspension components.
2.
Measure your race ride height in the rear.
3.
Set your race ride height in the front.
4.
Measure your rear race sag.
5.
Verify that you have the correct crossover gap
in the front.
6.
Measure your front main spring length at race
ride height.
1.
Carefully install your suspension components.
Please have a
qualified and knowledgeable technician install your components
checking for all the correct clearances and that all your suspension
components are moving freely.
2.
Measure your race ride height in the rear.
Make sure your
quad is race ready with tire pressures set and anything else that
will affect the height. Then stand on the foot pegs and have someone
measure to the bottom of the frame in the foot peg area.
3.
Set your race ride height in the front.
Now measure
your front ride height 22 inches forward of the foot peg area and
adjust the front ride height up and down by adjusting the preload on
the front shocks till the front is 0 - 1/4 inch higher in the front
for most applications. Feel free to contact us for exact settings
for your quad.
4.
Measure your race sag.
Place your quad
on a stand that is tall enough so that your wheels are suspended off
the ground and the rear suspension is fully extended. Now make a
mark on the subframe or other suitable place straight up from the
axle. Measure from the axle up to the mark. Next set the quad on the
ground and stand on the foot pegs and have someone measure from the
axle to the mark again. The difference in the 2 measurements is your
race sag. We run 4-5 inches depending on the application and the
rider. You can make small adjustments to this by turning your
preload nut 2-3 turns and you can make large adjustments by installing
stiffer or softer springs. For best performance you need to have
between 1 and 3 turns of preload. NEVER
RUN MORE THEN 5 TURNS OF PRELOAD.
5.
Verify that you have the correct crossover gap in the front.
Your crossover
gap is the distance between the crossover and what ever it contacts
as you move further down in the travel. The gap needs to be checked
at race ride height. It needs to be 3/16
- ½ inch. The smaller the gap, the stiffer the ride and the
better the cornering. The larger the gap the plusher the ride. The
crossover gap can be adjusted by adding or changing crossover
spacers.
6.
Measure your front main spring length at race ride height.
Measure the
front main spring length at race ride height. On a dual spring setup
7 to 7-1/8 inches is a good balance of plush ride and good
cornering. If the length is less you will need to install stiffer
front springs. If it is longer then that you need to install softer
front springs.
Notes:
1.
Feel free to adjust the compression adjusters to
your liking but do not run them fully closed as it will cause a
harsh sensation and can damage chassis components due to pressure
spikes.
2.
We set your rebound for you –PLEASE do not
change it .
3.
Shock covers on the front shocks are needed to
avoid main seal damage, shaft damage, and crossover sticking.
IF YOU HAVE ANY QUESTIONS, NEED ANY
ASSISTANCE, OR WANT CHANGES MADE TO YOUR SHOCKS – I NEED ALL THE
MEASUREMENTS FROM STEPS 1-6.
5.
Verify that you have the correct crossover gap in the front.
Your
crossover gap is the distance between the crossover and what ever it
contacts as you move further down in the travel. The gap needs to be
checked at race ride height. It needs to be 3/16
- ½ inch. The smaller the gap the stiffer the ride and the
better the cornering. The larger the gap the plusher the ride. The
crossover gap can be adjusted by adding or changing crossover
spacers.
6.
Measure your front main spring length at race ride height.
Measure
the front main spring length at race ride height. On a dual spring
setup 7 to 7-1/8 inches is a good balance of plush ride and
good cornering. If the length is less you will need to install
stiffer front springs. If it is longer then that you need to install
softer front springs.
Notes:

and can damage chassis components due to pressure spikes.
2.

3.
Shock covers on the front shocks are needed to avoid main
seal damage, shaft damage, and crossover sticking.
4.
If you have any questions, need any assistance, or want
changes made to your shocks – I need all the measurements from
steps 1-6.
IF
YOU HAVE ANY QUESTIONS, NEED ANY ASSISTANCE, OR WANT CHANGES MADE TO
YOUR SHOCKS – I NEED ALL THE MEASUREMENTS FROM STEPS 1-6.
If
you have any other brand of shock, or your shocks were converted by
someone else - The first thing you need to do is to verify that the
shocks are the correct length - if not they need to be repaired
before any of the previous info is applicable.
To verify that your shocks are the correct
length for your application – this can be done by sitting your
quad on 12 inch stands. Then checking your tire relationship to the
ground. Feel free to email or fax us with your specific application
and we can give you a recommendation. Here are a few basic setups.
Honda
XC – Rear tires
should touch the ground and front tires should be about ½ inch off
the ground.
MX – Rear tires
should touch if the back of the quad is lifted ¼ inch off the
stands and the fronts should touch the ground.
Yamaha
XC – Rear tires
should have 1/8 inch gap or just touch the ground and the front
tires should touch the ground.
MX – Rear tires should touch the ground and the front tires should
touch if the front of the quad is lifted ¼ inch off the stands.
How often should a shock be
serviced??
To
keep any shock performing good for a long time it needs to be
serviced and cleaned periodically. How often it is needed depends on
how extreme the shocks are used how serious a rider is about keeping
their suspension in top condition.
Example:
Pro
– Every National
Amateur
racer – 2-3 times per season
Trail
and general riding – Every 6 months
