INTRAX SUSPENSION 924S, 944, 944T, 944S, 944S2 & 968



Intrax suspension systems are custom built to fit your needs. Three different levels of performance are available in each of the three kits. Street, Track Day or Full Race set-ups in the RSA, IK2 and 4-WAY. The springs, valving range and length of the shocks and struts depends on which of those uses your targeting.

"RSA" 2-Way Adjustable Steel / INOX Mono Tube: High End Damping-System


The RSA is an RS with externally adjustable damping. The internals are more complex to give an even better damping characteristic. Different from our competitors, Intrax chooses for one single adjuster knob for both the compression and rebound adjustment. With this single knob the total damping can be adjusted over a wide range of 40 clicks from comfortable to sportive/hard.



Main Features:


  • Front Damper 40 mm upside down
  • Rear Damper 40-14 mm coilover steel
  • Damping adjustment both compression & rebound on one knob.
  • Heat control automatically maintained inside damper
  • Includes Springs
  • Camber Plates

By using one knob the relationship between compression and rebound always stays correct. Also different from most of our competition, our adjuster changed not only the rebound but also the even more important low-speed and high-speed compression damping. The RSA has an internal thermostat that keeps the damping constant, avoiding the harsh ride in the cold morning, and the loss of damping in the heat of the battle.

Options:


  • Black Titan

    The shock absorber set can be equipped with the "Black Titan" coating, which will be applied on the guidance- and piston rod. Black Titan is an development from military aircraft industry. Their engines must perform under the toughest conditions, they must function from +40°C up to -30°C. After they fitted their engines with Black Titan, the service interval was increased by 100%. Intrax decided that what is good for their airplane engines must be good for our shock absorbers. The Black Titan coating, which will be applied on the guidance- and piston rod, cannot rust and is extreme hard and smooth. The friction is lowered with these piston rods, reducing oil temperatures, improving traction and extending life time under the severest conditions.

  • Spring Rate Adjuster

    As an option we can equip a spring rate adjuster for the front and rear. The choice for hard or soft springs is an important setting. This stiffness is defined as the spring rate. Intrax now delivers a spring rate adjuster that solves the problem of have to change the springs to change the stiffness, and enables an optimum setting under all conditions, reducing setup time and purchase costs. By sliding the spring further into the spring rate adjuster, a part of the windings is excluded of the spring action and the spring becomes stiffer.

"IK2" "2-Way Adjustable Mono Tube : High End Modular Built."


The IK2 is a real high-end shock absorber for demanding street and competition use. The IK2 is build using the finest materials. The housing is made from 7075 aluminum. This guarantees low weight, maximum strength and optimum cooling. The IK2 damper is always chosen in the largest size possible for the most accurate damping control: normally a 46mm body with a 40mm piston and a 16mm piston rod. Mc. Pherson struts are normally converted from the standard 22mm piston rod to an upside-down system with a 40 or 45mm guidance tube for maximum stiffness and wheel guidance. This is especially important when the G-forces are higher than obtainable with the standard vehicle.



The above pictured IK2 kit is shown with the "optional" ARC (Anti Roll Control), Black Titan Friction Coating and Spring Rate Adjusters. Base priced kit does not come with these options.

ARC is done completely internally on the front struts, yet requires a external reservoir in addition on the rear shocks due to the lack of room with the smaller shock.

Main Features:


  • Front Damper 45 mm upside down
  • Rear Damper 46-14 mm coilover light weight
  • Damping adjustment both compression & rebound on one knob.
  • Heat control automatically maintained inside damper
  • Includes Springs
  • Camber Plates

Adjustable:


  • Rebound and compression damping-range in 50 positions.
  • Spring-preload fully adjustable.

Other Features:


  • Mono-tube damper construction.
  • Internal pressurized nitrogen reservoir.
  • Advanced thermostat valve for constant damping at whole temperature-range.
  • Modular built for endless flexibility.

Options:


  • ARC (Anti Roll Control)

    After years of development Intrax did it. They developed a unique way to drastically reduce unwanted roll (lateral and longitudinal). Your car will have the comfort and all the other benefits of driving with "soft" springs, until you take a corner, need to brake or drive through a putt hole/over a curb. Than ARC will control ride height with the feel of a sport setup. For the car it's a must have, because on the long roads/tracks, your suspension acts like a soft suspension and gives you al lot of traction and stability in the car. But the ARC will make sure that your suspension won't collapse on a unexpected put hole or high curb and your car will corner like it's fitted with a sport suspension. So for the first time you can have the benefits of a soft spring set up without the disadvantages of too much body roll and/or collapsing suspension in putt holes, jumps, curbs.

"4-WAY" "Top Off The Range, Highly Advanced Modular Mono Tube Damper"


The 4-way is Intrax's top product. The damper is adjustable in the low-and high-speed compression (bump), rebound and the overall range of the low-speed compression, these adjustments can all be adjusted separate. Unique on the Intrax system is that all adjustments operate stand alone meaning none of the changes in adjustment will influence each other making it very good to fine tune the setup. Also each click will make a difference when adjusted. The system is equipped with a heat device (thermostat) to insure damping force stability and optimum performance during all different operation temperatures. Finally the 1K2 system at your car is a upside-down system with a diameter of 45mm. This gives a lot of extra installation stiffness (less flex) in your McPherson suspension system. Which will have a very positive influence in the handling and feeling of the car.



Main Features:


  • Front Damper 45 mm upside down
  • Rear Damper with reservoir coil over
  • Damping adjustment both compression & rebound on one knob.
  • Heat control automatically maintained inside damper
  • Includes Springs
  • Camber Plates
  • 4-Way Spring adjuster included

Adjustable:


  • Low-speed compression damping base-adjustment.
  • Low-speed compression damping range-adjustment in 16 positions.
  • High-speed compression range-adjustment in 50 positions.
  • Rebound damping-range in 50 positions.
  • Spring-preload fully adjustable.

Other Features:


  • Mono-tube damper construction.
  • Pressurized nitrogen reservoir; piggy-back style or remote with hose.
  • Advanced thermostat valve for constant damping at full temperature-range.
  • Modular built for endless flexibility.
  • Fully rebuild-able and fully upgradable.

INTERNATIONAL ORDERING



TO OUR INTERNATIONAL CUSTOMERS:


In the past, we have used a separate order form for placing International orders. We have quit using that process and are requiring all customer to use the shopping cart system built into the web site and it's check out process.

If you simply want a quotation and are not ready to place an order, then cut and paste the contents of your shopping basket, take a screen shot of the basket, or make a list of items and send us a email requesting a quotation with shipping.

If you need shipping prices before you make your final decision to purchase, then you should request that quotation by email and not use the shopping cart checkout process because you will be paying for the parts at that time.

Since our shopping cart and shipping estimator will "NOT" correctly calculate shipping charges on International Orders, we have it set-up to where the shipping will be Zero Dollars ($0.00) when checking out. When the shopping carts address process learns you are not in the United States by selecting your particular country, that's when it switches to equal Zero. That does NOT mean shipping is free.

Upon completion of the check out process, you will have paid for your parts but NOT the shipping on those parts.

Once we look over your parts ordered and calculate shipping weights and box sizes, we will send you an E-Mail with at least one shipping option and maybe several. We utilize UPS, DHL and the United States Postal Service (USPS) to deliver your parts.

Once you pick a shipping carrier and agree to the quotation by returning the E-Mail, we will be sending a PayPal money request for the amount of the shipping to be collected. If the parts are expected to be shipping out quickly, then you may receive that email quickly. If the parts are going to need to be built or something is on back order from the list of parts, we may hold off sending that E-Mail until we have the shipment ready to go. It can vary from order to order as to how we do that. If you think you should be hearing from us quickly, but you don't, feel free to contact us.

If you have special shipping needs or requirements, during the checkout you will see a SPECIAL ORDER INSTRUCTIONS window. Enter that special information there.

A good bit of our business is International and we have been taking care of those valued customers since 1999.
