Hey team, this is a VERY quick and dirty breakdown of the Haldex Valve modification that comes along with our Haldex Unit. This is to make it easier for the installation of the modified valve that is needed to work in conjunction with Haldex Unit itself. We'll have more videos with instructions and descriptions coming soon.

Definitely interested in the "why" on this one! Thanks for the video!

Excellent music choice.

[@BryceJordanProductions]

Can you explain more as to why we'd wanna do this?

Thanks for this vid. More like this please.

Very nice please please make some options for the 19/20 Tiguan she needs it lol

Why is this value being replaced?

[@IrozMotorsport]

The valve gets an upgraded spring installed in it to allow for more fluid pressure, without the valve upgrade the unit doesn't do anything

[@hunterlane3323]

@@IrozMotorsport understood, more fluid = faster reaction time and more clamping force... With the controller are you able to set it up so the haldex response can be throttle based and come or come on under hard breaking to increase stability? I see that VanCity makes adjustments with this knob that was installed Had the UM haldex tune, it really changes how the car feels and have just been looking around at other options (this would be for a 7.5R)

[@IrozMotorsport]

@@hunterlane3323 The potentiometer adjusts the bias so that up to 50% of the power can be sent to the rear it is still throttle based and can likely work with the updates UM provided

Hey guys, interesting, do you stock the uprated spring, and if so do you have a link so I can purchase please 😁

[@photorocket4550]

This is strictly a interference fit?

[@IrozMotorsport]

The spring replaces the OEM spring and has a different spring rate which is what makes the difference

[@photorocket4550]

@@IrozMotorsport yes, thanks 👍. Is the two pieces of the valve an interference fit? It's not clear in the video as to how it stays together.

[@IrozMotorsport]

@@photorocket4550 yes it is an interference fit and the friction itself between the two materials is what hold it together

What is the benefit of this?
