4. ZeroValve - the last percent.

You gave it everything:

VCDS coded. QuickDump installed. DropForks mounted. Rear bump stops removed.

But the front still sits slightly higher than the rear?

Then the ZeroValve is your final step.

Why do you need it?

Even after all the modifications, your rear is lower than the front?

ZeroValve corrects this minimal height difference – with zero compromises.

Installation & Function

From factory, the front air struts come with a residual pressure valve.
This keeps a bit of pressure in the bag, even when aired out – for comfort and safety.

But for maximum drop, that’s a real showstopper.

ZeroValve replaces the OEM valve 1:1 – as a true plug & play adapter.
Just unscrew the original airline, remove the valve, install the ZeroValve, and reconnect the airline – no cutting, no modifications.

Result: zero residual pressure.Up to 1cm more drop.
And the best part: fully reversible at any time.

 

This is the final form.

You’ve come this far – now finish it.

With the ZeroValve, you unlock the last few percent:

Perfect symmetry. Maximum drop.
descend complete.
