New Springs = Alignment?

[mechtech2]

Odd ball stuff like air bag suspensions are not what I was talking about.
Simply, 99.99% of any car's ride height will not change with a blown strut or shock.

Quit dismissing the facts. Read what you posted.

Ordinary monotube shocks for conventional cars with well over 300 psi are low pressure? Quite common, too. Add to that that many new cars do NOT have gas charged shocks.

I just put new shocks on the front of my employee's ratty old 85 Buick and it rides higher. Hello?

C'mon.

I'll stand by my statements.
By FAR, shocks struts are low pressure.
It is VERY rare to have them support the car by air [nitrogen] pressure.
And how are you installing them? What special tool? A shock compressor?

I could not find shocks/struts that are not gas charged. At the shop, we gave up even asking. I'm sure a few specialty ones are out there.

This training page by Monroe sheds some light on the subject. It talks about low pressure (100- 150 lbs.)shocks that do not affect ride height.

In the bottom paragraph, it talks about high pressure mono tube designs that DO contribute to ride height management.

I get the impression (correct me, please)that most modern day cars are of the low pressure design.

Worn shocks or struts do not change ride height.
Springs do.
If someone does put in new springs, drive it for 100+ miles before an alignment.


Blown or extremely worn out struts will make it sit lower after the extra work load is put on the springs or vice versa.

I've blown out enough OEM struts with coil overs and lowering springs to see it happen over and over again.

Yeah, like the factory installed shocks on my 05 Silverado. Monotube high pressure!

I know, I know, it's a really exotic vehicle!
