can the sensor for the air ride be tricked?

[CBR_Raven]

I have added the 2" torsion key lift to my H2 and it sits higher in the front now and kinda sags in the rear. Is there anything I can do to trick the sensor for the air suspension to ride higher?

where do I adjust the sensors...what tool do I need to do this? instructions needed please.

Thanks, I will take a look at it when I get some time.

Can someone post a pic of the sensor location? I've looked under there a couple of times, and can't really figure out where it's at...

I don't see where they can be adjusted, guess I will take a closer look after some more coffee. I know my friends H2 seems to sit almost an inch higher and she doesn't have air suspension.

FWIW On the Fabtech lift kit, which is not suitable for air ride H2's with the non adjustable sensor, it uses a bracket with plenty of room for adjustment.

I may well be wrong, but from what I've been told there is adjustment in the air ride on the earlier H2's, although the manual says there is no adjustment. Maybe it is at the other end of the sensor, the part attached to the uppoer control arm.

I will check it out later and see if theres any play to slid the sensor with the bolts loosened up. It always adjusts apon startup, so I think the hieght difference bewteen our rigs was.

A: had been sitting for hours.
B: my tires are about 5k away from being toast and hers are like brand new.

Ahhh..was wondering what the h*** that was...

A while back SteveR told me that he and some others put some kind of "spacer" to fool the sensor in thinking it's lower than it is. I don't have air ride, so can't offer more than that

from looking at it you would have to make the rod longer to get it to respond in making it higher. it would effectively push the arm up making it think the vehicle was low

[Yetti]

as for shimming the switch you could add washers to the switch on the far side to rotate the body of the switch towards the arm of the switch. I would think one or two small washers could add an inch or two to the ride height

You can ask your dealer to raise the rear via computer programmer. Mine was done and raised the rear about 1 in. Not all dealers will do this but I know first hand it can be done.

So with the torsion bars cranked up and the rear raised....you should fit 37's pretty well...

You are right. The technician will use the programmer to raise the ride height in the rear and calibrate the sensors and computer for the proper ride height. Then all four corners of the car will be calibrated correctly. I believe its called z height adjustment. You can fool it, but you risk not having the car level, unless you mess with it long enough. Messing with the height can effect the alignment in the front. Trust me, I've learned this over the past few months.

My dealers refused to adjust my z height...
