INTRAX quality starts at the source. All INTRAX springs are produced
under strict quality guidelines assured by ISO 9001 standardization. From
the raw Chrome Silicon sourced from Bekaert in Belgium to our box producer
in Germany, INTRAX and its suppliers are held to the highest standards in
the industry. While our European and private label products carry TUV certification
for the German, Austrian and Danish markets, INTRAX US versions are produced
identically, even without requirements for TUV approval. Don’t be fooled by
manufacturers who claim to carry TUV approval on US version springs; they
are at best stretching the truth to sell more product. The United States,
with their stringent safety standards usually require a unique design from
their European counterparts. This changes the design enough that it would
require another TUV certificate (again, not required for US). INTRAX is proud
to offer unsurpassed quality in the US and Europe; no misleading sales pitches,
just the finest springs.
INTRAX is an elite spring manufacturer. All INTRAX springs are cold
wound on either Wafios CNC, or our own WM series of PC-based coiling equipment
(sold to manufacturers worldwide). Manufacturing our own spring winding equipment
puts us in an elite league, as none of our competitors have mastered this
skill. INTRAX springs up to 16mm are produced from the highest quality Chrome
Silicon wire, while 17mm and up are produced from Chrome Vanadium.
What makes INTRAX springs better? INTRAX designs most of its
lowering kits with progressive rates, to satisfy the two features you've asked
for most. First, the lowered look. Most other brands' springs are linear rate,
as this is cost-effective but doesn't necessarily provide the visual effect
you desire. By designing a progressive spring, we achieve the lowered look
while maintaining safety standards of spring preload at suspension droop.
The second requirement is ride quality. Since most of you identified that
you drove 90% of your mileage to and from work, you wanted to retain some
ride quality enjoyed with OE springs. If you're driving to work on a racetrack,
"Sport" or "Race" springs from other brands may be for
you. INTRAX progressive springs provide high performance looks and comfortable
ride quality.
INTRAX creates the finest springs, from start to finish.
INTRAX springs begin the forming process with cold winding to the most exacting
standards. Within two hours of forming, springs are stress relieved in an
oven (not to be confused with heat treating), and then shot peened to remove
surface imperfections and further relieve internal stress. This can extend
service life of a spring up to 200% or more. Next, the spring is "blocked"
(wound to a longer length than required, and set in a hydraulic press to obtain
designed free length). This eliminates the "settling" other brands
require, due to the lower cost of their production processes. Finally, springs
are Phosphate coated for corrosion resistance, and electrostatically powder
coated to ensure a lifetime of outstanding looks.
SUPER SPORT
Super Sport
kits provide aggressive drivers with substantially stiffer spring rates and
some of the lowest fitments available for street cars, Super Sport springs
lower vehicles 2.25"-2.5", providing race car looks with handling
to match. All Super Sport kits are made with the same quality material and
design standards used with our lowering sport spring kits. Super Sport lowering
springs are designed to be used with aftermarket sport shock absorbers. Minor
modifications or camber kits may be required.
INTRAX CAMBER KITS
The installation
of any INTRAX lowering kit requires that the vehicle's alignment be checked.
Depending required to specifications on the year, make, model, mileage and
general condition of the vehicle, a camber kit may be required to return the
vehicle to within factory specifications. Correcting a vehicle's camber to
factory specifications ensures even and proper tire wear. In some cases, an
INTRAX camber adjustment kit is needed. INTRAX offers it a variety of camber
correction kits, including full replacement control arms, to camber bolts,
which provide from -2º to +3.25º of adjustment, depending on the application.
ARS
The INTRAX ARS concept was developed as an uncompromised
coilover system for street and performance use. INTRAX chose to design a system
based upon their IRS modular Motorsport Damper's which are widely accepted
at the highest level of Motorsport. This eliminated the need to buy parts
from other shock companies as our competition does.
The INTRAX ARS coilover shocks are of a Mono-Tube high-pressure
design. All Intrax ARS coilover are pressurized with the inert gas Nitrogen
at 11 to 12 Bar. That's 11 to 12 times the pressure exerted on your body right
now. This helps maintain consistent dampening at the most extreme piston shaft
speeds. Intrax ARS coilovers also feature a large diameter specially heat-treated
aluminum body which increases shock volume up to 150%. The utilization of
aluminum and the large volume make the INTRAX ARS coilovers thermally stable
under the most demanding of conditions. In addition the INTRAX ARS uses one
of the largest pistons in use at 45mm and a robust piston shaft of 22mm for
Mac Pherson struts and 14mm on shocks. This creates a large displacement difference
between the compression and rebound stroke allowing for better low speed dampening
characteristics. All of these features are constructed on a modular system
derived from our motorsport IRS program. This allows us to offer the same
high quality services to the general public available previously only to our
motorsport customers. INTRAX offers custom valve setting or rebuilding for
drag racing, amateur road racing and autocross.
All of this adds up to make the INTRAX ARS coilover’s
the finest on the market today.

ARB
All INTRAX Anti-Roll Bar (ARB) kits are engineered specifically
for the vehicle that they are offered for. INTRAX has designed its ARB’s to
replace the original equipment bars and utilize all of the factory mounting
points. This eliminates the need for additional brackets and clamps which
typically reduce ground clearance. The ARB kit has been designed to be used
in conjunction with INTRAX lowering kits and the ARS coilovers.
All ARB kits feature bars with increased rates. This
is accomplished by increasing the diameter of the bar or its wall thickness
on its tubular applications. ARB’s are manufactured to meet or exceed original
equipment specifications and are powder coated in rich INTRAX purple. INTRAX
has invested a great deal of time in researching and testing each fitment
to determine the correct designs even offer several settings to allow you
to fine tune the balance of the vehicle to better suit your driving style.
ARB kits feature polyurethane bushings and top quality
hardware, along with a set of comprehensive instructions.

FAQ
How does Intrax provide incredible performance and comfort?
Intrax designs progressive rate springs that provide
you with the two features you requested most. The first, lowering the vehicle
and center of gravity to noticeably change looks and handling. The second,
to maintain the comfort qualities of your original equipment ride. The only
way this can be achieved safely is with a properly engineered progressive
spring - one that has two or more spring rates built into its design. Softer
initial rates offer better traction and comfort, while stiffer rates reduce
body-roll and provide better response during acceleration, cornering and braking.
Does wire quality really matter? And why are Intrax
springs cold wound?
Yes! Intrax utilizes only the highest quality Chrome
Silicon (CrSi) wire in production of its lowering kits. CrSi wire, as supplied
by Bekaert, is heat-treated to its appropriate hardness before leaving the
foundry, ensuring even tensile strength throughout the wire. Intrax produces
all of its springs by cold winding, with no further heat-treatment. Others
claim they cold wind, but if they produce their springs from anything but
CrSi, then the spring requires heat treatment; this is the same as hot winding.
Heat treatment is usually carried out in small furnace a few at a time, allowing
for great variations in tensile strength, fatigue life and quality.
How can Intrax
offer a limited lifetime warranty while others don't?
While part of the answer is listed above, the rest is
because we do not rely on others to do out work. Intrax quality starts with
our in-house design and testing. All of the production occurs under one roof,
from cold forming to the rich Intrax purple powder coat protection each spring
receives. Only by utilizing ISO9000 standards can we assure this high quality.
As a matter of fact, all of our springs meet or exceed the toughest standards
in the world. Including TUV, DIN, ABE, JIN and SAE to name a few.
Can I use my stock struts or shocks?
Yes, Intrax designs all of its progressive lowering
kits to work with the original equipment shocks. However if you have 20,000
miles or more on the odometer, consider upgrading. A good sport shock is always
a wise investment to ensure the ultimate performance and handling your vehicle
can obtain. In addition, most OE shocks start showing, although subtle, a
remarkable reduction in dampening ability around this mileage.
Do I need to get an alignment? And do I really need
a camber kit?
Yes and Maybe. Yes, you should always have your alignment
checked and adjusted any time you alter the ride height of your vehicle. Lowering
your vehicle usually results in what is called negative camber, this will
increase traction but also tire wear. Camber kits will allow you to adjust
this for the best compromise between performance and tire wear.
Will my Intrax springs settle and how long will it take?
No, Intrax blocks or sets all of their springs as part
of its production process. This means that most vehicles will be lowered to
the correct height immediately. Some vehicles, because of the design will
take a day or two to settle, but this is because of the rubber bushing and
isolators readjusting to their new position rather than the spring. Keep in
mind that the lowered height listed in our application guide is based on new
vehicles with stock shock absorbers. This may vary depending on option equipment,
age of stock springs, gas shocks or upper strut bearing condition.
What do the Intrax ARB's, or sway bars do?
Intrax has designed a range of sway bars more appropriately
referred to as Anti-Roll Bars or ARB's. Intrax ARB's are designed to reduce
body roll without an undesirable increase in wheel rate. This will help maintain
your OE ride while increasing the cornering potential of your vehicle. In
addition, some of the Intrax ARB kits are adjustable. This allows you to fine
tune the balance of the car to suit your driving style.
Why should I buy an Intrax ARS coil-over shock rather
than a cheaper sleeve kit?
Intrax has based its ARS coilover shocks on its successful
line of racing shocks, but offered at a much more affordable price. The ARS
line of shocks is a modular, high-pressure gas mono-tube design, allowing
for easy rebuilding and re-valving which is not available from other brands.
Intrax ARS also allows for easy ride height and rebound adjustment. All ARS
kits are equipped with a main spring suited to the application, and a helper
spring to provide the proper spring preload while eliminating noise. Sleeve
kits, while cheap, only offer ride height adjustment.
