P
roject Raptor has been
lacking in the suspension area for some time now. To fix this
problem we contacted Works Performance in Canoga Park,
California. Works has been building high perfornance shocks
since 1973, so we knew we could get some race ready shocks to fit
our application.
We chose
the Pro Series Damping-Adjustable Piggyback shocks, which are
available with both compression and rebound adjustments, and a
triple rate spring. This shock has all the high-end features. It
incorporates a 1-3/8-inch piston design and is constructed with a
billet aluminum reservoir web and eye with a steel pressure
cylinder. All of the machined shock components are manufactured at
Works Performance on state-of-the-art CNC milling and
turning machines.
The Pro
Series shocks have a heavy-duty 5/8" C1050 induction-hardened high
tensile steel shaft and a military spec coating to dissipate heat
and resist corrosion. It has a threaded spring preload and
spherical bearings with dust excluders. The damping is externally
tune-able through 18 rebound and 18 compression adjustments.
Works accomplishes this with a computer-calibrated check
ball, spring and orifice damping system that is unique in the shock
industry, and in fact was invented by founder Gil Vaillancourt.
This allows the damping curve to be specifically tailored to the
combination requirements of rider, machine and terrain. The springs
are wound from chrome-silicon wire, shot peened and set to
solid.
Enough on the construction
details -- how do they work?
Adjusting Sag
1) Lift the front wheels up off the ground so your front
suspension is fully extended.
2) With the
wheels off the ground, measure the distance from the top of your
spindle to some point straight above it on the ATVs frame. Write
this dimension down.
3) With all your
riding gear on plop your butt on the seat with your feet on the
pegs in your normal riding position. Now have somone measure the
distance in the same place as the first measurment. The difference
between the 2 measurments is called the "ride height sag".
4) Now adjust your preload so that your "ride
height sag" is about 30% of your total suspension travel. Example:
If you have 9" of total travel you should have about 3" of ride
height sag.
If you have too much sag the
chassis will bottom out frequently over bumps. Not enough sag and
the ride will be stiff and your center of gravity will be
unneccessarily high. |
We received our new Works Pro Series Shocks
just in time for the Whiplash race in Wickenburg. We did not have
time to do any testing so we just bolted them on as they were set
straight from Works. We had ordered ours for a 180lb rider
in desert terrain. We adjusted the sag in the front per the
instructions, and we were off to the races.
*See the sidebar on how to accomplish this."Sag" is defined
as the distance the suspension settles from its fully extended
position with a rider on board.
We had been fore-warned that the Wickenburg course was one
of the roughest on the Whiplash circuit. They were not kidding.
This course was 17 miles of rough trail and whoops, with no pattern
to it at all. Our new Works Pro Series shocks worked
absolutely flawlessly. We were able to tackle the whoops much
faster than we could even think about prior to this upgrade. The
front suspension of Project Raptor was soaking up the bumps
incredibly well, and despite thick dust, I was able to pass about
four riders in my class during the first lap. Unfortunately I had
screwed up adjusting the clutch just before the race, and lost it
entirely on the second lap to end my race.
Since Wickenburg we have been putting many miles on Project
Raptor. The Works shocks have worked as designed and we can
finally use some of that additional power that we added. We
definately should have scheduled this upgrade sooner in the project
timeline.
At a whopping $899 suggested
retail, these Pro Series Shocks may require you to save your
pennies, but our experience so far shows they are well worth it. If
that's too much of a pinch to your wallet but you still want to see
awesome ride improvement, you can get the Pro Series with
adjustable compression only [not adjustable compression/rebound]
for $699.
All Works shocks are
serviceable, and are covered by an exclusive 30-day
"Performance Guarantee" -- the ride and handling will meet
your expectations or Works will re-spring and re-valve the shocks
at no charge, except for shipping. That's a pretty awesome
claim, and solid service to back it up.
Next up for Project Raptor and our Works Pro Series
shocks is the BITD Las Vegas 200, to be run the first weekend in
December. This will be the longest race we have put them up
against, and we are confident they will work well.
