Welcome to the
most advanced suspension ever designed for a snowmobile. Many years
of design and testing teamed with highly advanced materials allow
NEXTECH Industries Inc to provide what will soon be considered the
bench mark of what all current suspensions are judged.
We wish
everyone could simply ride one of our rear suspensions but that is
not possible so we will try to explain the key mechanical features
that provide significant advantages.
The first and
most noticeable feature is the use of a single shock. At first
thought people think that this was done only for weight reduction.
Weight reduction is a small side benefit but the design of the
coupling system and geometry allows for full force of the shock to
be transferred to the front, rear or the entire skid as required.
The most common after market design has 2 vertical shocks that are
of falling rate and even worse than the falling rate is that they
have reduced mechanical leverage near lower travel. These mechanical
features used on a dual vertical shock suspension are hard to tune
because they are stiff in top and middle travel but lose most of
there force near bottoming when you want it most. Our design is a
little more complex and expensive to produce but with linear shock
stroke and a high spike in shock force near bottom you achieve a far
better ride.
The biggest key
feature to the single shock suspension is its coupling ability.
Coupling is not a new thing to snowmobile suspensions and we have
been running them for years but did notice some drawbacks and room
for improvement. All current coupled suspension connect the front
arm to rear arm threw the rails allowing for control of skid pitch,
ski lift and ride. Using this method is the lightest and simplest
but we will try to explain the drawbacks compared to our system.
On a typical
coupling system one arm will travel by itself until engaging the
couple block and then it pulls or pushes the other arm witch takes a
lot of force at the start but then as the suspension travels further
the force from one arm to the other slowly gets mechanically
trapped. This is the reasons people find a coupled suspension hard
to tune for a good ride. There also is a limited range of adjustment
on most systems to accommodate all riders.
The mono shock
coupling system transfers force between the two arms via a coupling
bar providing no harsh engagement and a fully consistent sharing of
force. This is only suspension that can be fully coupled for a
constant approach angle allowing for reduced trenching and
unbelievable ski pressure even with the most powerful turbo sleds.
Another key to this system is you can have far longer limiter strap
settings than other systems to maintain travel required for big
bumps. Since the suspension is so adjustable it can also be set for
instant ski lift and transfer like a drag racer might require or
even allowed to rocker free if many miles of sit down riding is
desired. Basically this is the most universal suspension ever
developed.
Reliability is
of a major importance because we all know if it is broken its not
that fast!
At NEXTECH our
goal is to build the best so all of the best parts and processes are
used even if they are not the cheapest or easiest to produce. Carbon
fiber is the biggest key to light and strong but we also use the
best alloys including aircraft aluminum fasteners and shafts.
Basically everything is the best including the special bushings
bolts and even the limiter straps are of a exotic material. This
allows us to produce parts as light as powder specific pieces with
race track reliability.
