Which air bag size for rear axle (PU 51')

[ACII]

Hello together,

at the moment i am also improving my rear axle suspension.

Therefore i bought a heavy duty triangulated link.

I want to install the 4link together with a air ride suspension...

The aim is to slam the truck to the ground, but also the get a comfortable driving position with a huge clearance to the street.

THerefore i bought a set of air bags with folllowing dimensions:

Diameter 7.25in extended height 14in closed 3.5in) 2600 triple airbag

So far i dont know if the size of the bag is the right choice...

I am not sure to get the right hight with the right pressure.....

i am afraid to need to drive with 100 psi to get the maximum hight.

But with a smaller bag i dont have the needed travel

Hope you have some informations for me

Thx
Achim
